Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 15-20

Dopant profile analysis by successive anodic sectioning and sheet conductivity measurement is very well known. However, this requires prior knowledge of mobility as a function of dopant concentration for which there is considerable divergence in data in the literature. A new method has been given in this paper which does not require the knowledge of mobility data. Here Hall voltages are measured after...

Thin film flexible CuInSe ₂ (CIS) solar cells have been fabricated for the first time on light-weight polymeric substrates. Evaporated Cu-In alloy precursors were selenized in H ₂ Se atmosphere at around 400°C to grow the CIS absorber layers. Low temperature techniques which are compatible with the polymeric substrates were used to deposit the window layers of CdS and ZnO. The demonstrated...

Measurement of solar cell parameters using impedance spectroscopy

M.S. Suresh

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 21-28

Measurement of solar cell parameters is important for the design of satellite power systems. These parameters can be measured using impedance spectroscopy and an equivalent circuit model developed. In this study parameters of a Back Surface Reflector Field solar cell (BSFR) have been measured using impedance spectroscopy. The results show high diffusion capacitance of BSFR cells and their exponential...

Photoelectrochemistry of poly(3-methylthiophene), I: Surface morphology and thickness effect

L. Micaroni, M.-A. De Paoli

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 79-91

Photocyclovoltammetric experiments with films of poly(3-methylthiophene) under polychromatic light irradiation show a p-type semiconductor behavior in the reduced state, with a flat band potential of 0.18 V. The photocurrent depends on film thickness and surface morphology. Films with different thickness were characterized by scanning electron microscopy, indicating a globular morphology with globule...

Computer modeling of the performance of some metal/dielectric multilayers for high-temperature solar selective absorbers

J.H. Schön, E. Bucher

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 59-65

Solar thermal performance of metal/dielectric multilayer coatings of various material combinations was calculated using a computer program. The simulated material combinations were selected with respect to their use in high-temperature (T 500°C) solar thermal energy conversion. Maximum solar absorptances α = 0.94 with low emittances ε = 0.16 (T = 1100 K) were calculated for Al ₂ O ₃...

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 1-14

The role of AR coatings in microgrooved solar cells having different slat angles has been studied in detail deriving the expression of the reflection coefficient for various slat angles for unencapsulated and encapsulated cells. The role of flats of texturized surfaces have also been studied. It is shown that there is little influence of the AR coating when the slat angle is less than 55°, while the...

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 67-72

Tungsten diselenide intercalated with indium p-In ₀ _. ₅ WSe ₂ as the semiconducting base layer has been used in the film photocell ITO/WO ₃ /In ₀ _. ₅ WSe ₂ . The short-circuit current I _s _c of that photocell equals 19.20 mA cm ^- ² , the open-circuit voltage V _o _c = 0.57 V, and the photovoltaic conversion efficiency...

Improvement of the optical properties of electrodeposited CuInSe ₂ thin films by thermal and chemical treatments

C. Guillén, J. Herrero

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 47-57

Cu, In and Se have been codeposited in thin films by potentiostatic one-step electrodeposition. The as-deposited material has shown direct optical transitions attributable to the CuInSe ₂ semiconductor, but also additional absorption corresponding to another semimetallic phase. The secondary phases are selenium and copper selenide compounds which have been determined by composition measurements...

Effect of air annealing on the electronic properties of CdS/Cu(In,Ga)Se ₂ solar cells

E. Moons, D. Gal, J. Beier, G. Hodes, more

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 73-78

The effect of air annealing on state-of-the-art, solar-cell-quality CdS/Cu(In,Ga)Se ₂ heterojunctions has been studied using contact potential difference and surface photovoltage measurements. The annealing treatment is shown to have no significant effect on the band lineup of the heterojunction. However, the surface photovoltage spectral response increases markedly upon air annealing. These...

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 29-36

Observed reverse current-voltage characteristics of the single crystal silicon and gallium arsenide solar cells have been analyzed. Physical mechanisms behind the junction break-down in silicon cells and current break-down in gallium arsenide cells have been identified. Preliminary estimates of the diffusion capacitance in GaAs cells have been presented.

Solar Energy Materials and Solar Cells > 1996 > 43 > 1 > 37-45

Indium doped ZnO thin films have been prepared on heated Coming 7059 glass by the pyrosol spray method. It was found that indium doping has an important role in grain growth at high substrate temperature. Indium also was used to improve the electrical properties, acting as an N type dopant, and we obtained highly conductive ZnO:In thin films with a resistivity of 3.0 10 ^- ³ Ω cm. At...
