TITLE: On the short-wave sensitivi ty of photovoltaic elements on the basis of

TOPIC TAGS: cadmium sulfide, photoelectric cell, photoelectric effect, oxygen

ABSTRACT: If a high vacuum is maintained during the preparation of a CdS-Cu photo-
voltaic element, the back-irradiated cell will exhibit a marked sens'itivity in the
400-500 pm range, with a supplementary maximum at 420 pm. This short-wave sensi-
tivity will disappear and will be replaced by a shift toward the infrared region if
the cell is allowed to stay in contact with atmospheric vapors and gases. The above
observations were made with the use of a photovoltaic element obtained by the thermal
evaporation of cadmium sulphide onto a copper-clad glass substrate and covered with a
semitransparent aluatinum. film. The whole process was performed in a vacuum chamber
at 10-5 mm Hg. At frontal illumination of the vacuum-prepared cell, through a semi-
transparent copper film, the element showed a similar sensitivity to 400-500 lim.
wavelengths. The authors attribute. the phenomenon to 1) the damping of short-wave
CdS sensitivity caused by water vapor, which increases the rate of surface recom-
bination of carriers, and 2) an increase of long-wave sensitivity caused by the pene-

tration of oxygen into the CdS lattice. Since the glass substrate and the ccpper fila
protect the semiconductor from atmospheric elements better than the aluminum film, no
shift of sensitivity was observed when the frontally illuminated vacuum-produced cell
was kept in contact with air. Orig. art. has: 3 figures. [ZLI

ABSTRACT: Photoelectric properties of sintered films with a cadmium
sulfide base have been investigated. It is shown that the photocon-
ductivity of coagulated films is determined by the-volume of cadmium
sulfide microcryntals. Great photosensitivity of the films is
attainable only within a narrow temperature range of sintering, which
in some cases'reaches 1010. Samples vith high stable photosensitivity~_
in the UV spectral zone (350--420 nm) were obtained. Orig. art has: 2..

ABSTRACT: The solution of some problems in mathematical physics is
reduced to finding in the space xOyz a harmonic function

method for an approximate solution of such a problem. It
is assumed that F(XYZ,C) = 0 is the equation of the sur-
face family S of the level of a function w = w(x9y,z), and
the surface S
belongs to the S-family., The function w9
0
defined as an implicit function of x,y and z from the equa-
tion F Z-x,y,z,c(w)-7 ~ o. is sought from the condition that
it satisfies the Laplace equation, i.e.:

the problem of locating round holesof given arbitrary radii on arectangular blank
where there are limitations on the distance between pairs of holes a nd between the-
holes and the perimeter of the blank. The general problem and two examples of spf~-

of different diameters in the smallest possible.rectangular blank'when,no spacing
is required between holes or between them and the perimeter;'and (2) the same prob,-

ABSTRACT: The problem df the best (in a certain sense) distribution of bodies
in a given domain (for example, the problem of miniaturization of electronic equip-
ment) is reduced to establishing algorithms by which the condition for intersection.
of bodies can be automatically established. The six numbers X. Y, zo 4$p 0.9 a 01 of
a are Euler angles) which determine the location of the relative coordinate system
X' Y' Z' with respect to a fixed coordinate system XYZ are called the parameters
of the allocation of the body. The general form of the equation of the allocation
of the body and the general conditions for the intersection of two bodies are written
It is pointed out that the application of the derived intersection conditions to
particular cases is associated with certain difficulties in connection with
calculating the maximum of a certain function. The author describes algorithms for
deriving the intersecting conditions for spheres, polyhedrons, right circular

SOURCE: Optika i spektroskopiya, v. 20, no. 4, 1966, 701-708
TOPIC TAGS: light reflection, surface roughness, light diffraction, geometric
optics, light scattering, light polarization, optic brightness
ABSMACT: - The authors point out in the introduction that the two standard methods,,'
used to investigate the interaction between light and a rough surface, the dif-
fraction method and the geometric-optics method, wherein the rough surface is as- I
sumed to be a random aggregate of microscopic areas, each reflecting separately,
have actually very little in common. The purpose of the present investigation was-
to investigate the acattering properties of rough surfaces in polarized lient. and
explain some of the observed phenomena on the basis of both the geometric-optics
and diffraction concepts. The experimental setup used for this purpose (Fig. 1)
is based essential]Zr on a brightness-measuring apparatus described by the authors
earlier (Tr. GOI v. 24, wo. 143, 3, 1955). The measurements were made on a plate
of black glass with refractive index 1.515, one surface of which was polished and

the other one was roughened mechanically. The degree of polarization and depolari-'
zation of the li6ht beam was determined for different angles and compared with theJ
calculations based on both approaches. The results show that the zero-order dif-
fraction approximation is more detailed than the geometric-optics approximation,
and provides a sati.-3factory explanation for the depolarization of the light and
for the dependence of the polarization on the scattering conditions. It also ex-
plains the shift of the maximum of the scattering indicatrix toward the larger
observation angles. Orl art. has: 5 figures-and 3 formulas.

ABSTRACT: The value of the coefficient of diffuse reflection for a freshly sprayed layer of
MgO about 3 mm thick was studied by means of an integral photometer. . The optical proper-
ties of MgO were measured at 220-1000 nip, using for this purpose the "two-parametric"
theory of the transmission of radiation through a light-scattering medium, and the problem of
the accuracy of the measurements is examined. Employing this theory an expression Is
derived for the absorption coefficient of MgO particles. The error in determining the coef-
ficient of diffuse reflection was about 0. 5% for the ultraviolet region and about 0. 3% for the
visible and infrared regions. A calculation of errors Involved when determining the absorption
index yielded a total error in this determination of about 25% for the visible and near-infrared

TOPIC TAGS: light reflection, light,scattering, light transmission, light polariza-
tion, plant ecology
ABSTRACT: In view of the fact that earlier similar studies were restricted to re-
flection, transmission, and absorption of the leafas a whole, and to spatial distribV-
tion of the light scattered by the leaf, the authors have studied the structure of th
light flux produced by interaction of plane-polarized light with the leaf material.
The use of polarized light made it possible to determine quantitatively the magnitude
of each of the spectral components. The experiment was carried out with a gonio-
spectrophotometer described elsewhere (uFzh v. lo, No. 1, 87, 1965), equipped for
polarization measurements. The spectral region investigated was 4o0 - 1200 run. Both
clull-surface and glossy leaves were investigated (Artocarpus integrifolia and Ficus
australis, respectively). The experimental procedure is briefly described. The ex-
periment made it possible to separate and measure quantitatively the polarized part Of
'the surface component, the depolarized part of the surface component, the polarized
part of the inner component, and the depolarized part of the inner component so that,

an expression for the flux reflected from the leaf in the form of four partial com~-
.ponents could be derived. A study of the brightness distribution of these components
as a function of the wavelengrth shows a strong wavelength dependence in the case of
glossy leaves, a lesser dependence in the case of dull leaves, and no dependence what-
ever in the case of fuzzy leaves (Ficus carica, Solanum tuberosum, Strobilanthes
glomeratus, and others). A table is presented showing the relation between the
spectral coefficients of reflection for normal incidence for three types of leaves
in the range from 4o0 to 96o run. Orig. art. has: 4 figures, 3.1 formulas, and 3

ABSTRACT: After having explained the essence of the oscillntory-dis-
charge method, the author describes 2 Soviet electronic oscil-
lographs. Me first is called OZhO-3-, It is equipped with
.single-action slave sweep, and can detect cable defects within
the range of 10 or 12 km. Its operational precision is plus-
minue 20 m for a stretch of 2 km. The apparatus needs a
photographic outfit for recording oscillations. For this
purpose the author recommends FED, "Zorkiy" or 'Kiyev" ca-
meras. He gives operational instructions and shows how the
distance of the traced defect is to be calculated. The second
electronic oscillograph is called IPV-3 (apparatus for measur-
ing amall time intervals). It was developed by the tech-
nicians of the Lenenergo (cable network of Leningrad). Some
improvements have been introduced by-TsNIEL (Central Scien-
tifiz Research Electrotechnical Laboratory) of MES. The
Card i/2 apparatus received the, name of EIIAKS-3 (electronic micro-

(for 1,000, 3,000 and 6,000 m). Its precision is plus-minus
1 Operational instructions are also given by the author.
For further, completely-precise localization of the defect,
the E.,uthor proposes an acoustic method as most convenient.
A supplementary remark of the editor reads that the present
article is the last one of a series devoted to the cable de-
fect tracing with the help of modern electronic devices.
The first articles appeared in Enere,-eticheskiy byulleten',

mula are compared and the following conclusionsare drawn:
the Orgenergoneft' method is the most exact of existing methods,
but it must be checked for how long the specific power con-
sumption curves based on a previous detailed study of "typical"
wells are in fact viable. The use of semi-empirical formulae
is justified in spite of their inaccuracy due to the ease and
s-jeed with which they can be applied. A modified version of

problem. Further results were obtained by Gnedenko and
L
Dw(P, q), A.7'(p, q), respectively, the maximum and mini-
mum of w.(J), when O;Sp;Sj;Sq;S2n. The author obtains
the joint conditional distribution of the k-dimensional ran-
dom variable (Dj+(0, 2n), D~+(I, 2n), - - -, Dt% 2n)) for
given values of w.(0), w.(1), - - -, w,#), and also the corre-
sponding unconditional distribution. Next she derives analo-
gous conditional and unconditional diptributions for the
2k-diinensional variable
(D~+(O, 2n), D~-(O, 2n). - - -, D~*(k, 2n), D~-(k, 2n)
!n each case the limiting distribution as n--+co is obtained.
Finally the distribution of the maximal term of the sequence.
Jw.(J)J is given together with its limiting form. As an
interesting corollary one gets that the probability that the
sequence (w.(J) I assumes its !Wimum atone and only one
place j with O
