Abstract

The dependences of the open-circuit voltage, fill factor, and efficiency of the thin-film CdS/CdTe solar cell on the resistivity {rho} and carrier lifetime {tau} in the absorbing CdTe layer were studied. In the common case in which the uncompensated acceptor concentration and the electron lifetime in the CdTe layer are within 10{sup 15}-10{sup 16} cm{sup -3} and 10{sup -10}-10{sup -9} s, the calculation results correspond to the achieved efficiency of the best thin-film CdS/CdTe solar cells. It was shown that, by decreasing {rho} and increasing {tau} in the absorbing CdTe layer, the open-circuit voltage, fill factor, and efficiency can be substantially increased, with their values approaching the theoretical limit for such devices.

Modification of electron states in CdTe absorber due to a buffer layer in CdTe/CdS solar cells

Journal Article Fedorenko, Y. G., E-mail: y.fedorenko@liverpool.ac.uk ; Major, J. D. ; Pressman, A. ; ... - Journal of Applied Physics

By application of the ac admittance spectroscopy method, the defect state energy distributions were determined in CdTe incorporated in thin film solar cell structures concluded on ZnO, ZnSe, and ZnS buffer layers. Together with the Mott-Schottky analysis, the results revealed a strong modification of the defect density of states and the concentration of the uncompensated acceptors as influenced by the choice of the buffer layer. In the solar cells formed on ZnSe and ZnS, the Fermi level and the energy position of the dominant deep trap levels were observed to shift closer to the midgap of CdTe, suggesting the mid-gapmore »« less

Tin oxide stability effects{emdash}their identification, dependence on processing and impacts on CdTe/CdS solar cell performance

Journal Article Albin, D ; Rose, D ; Dhere, R ; ... - AIP Conference Proceedings

High efficiency polycrystalline thin film CdTe solar cells involve the growth of CdTe films on CdS/SnO{sub 2}/glass substrates. The CdS layer in such a structure is commonly reported to benefit from a brief hydrogen anneal prior to the deposition of the CdTe film. In this paper, we show that the SnO{sub 2} layer can be susceptible to reduction in H{sub 2} and that the degree of susceptibility is dependent on the type of SnO{sub 2} used. Chemical vapor deposited (CVD) SnO{sub 2}/glass substrates (Solarex Corp.) show the most resistance to reduction while room-temperature sputtered SnO{sub 2} films show the leastmore »« less

Study of ZnTe:Cu back contacts on CdTe/CdS thin film solar cells

Book Tang, J ; Feng, L ; Mao, D ; ...

Vacuum-evaporated Cu-doped ZnTe films have been studied as the intermediate layer between CdTe and metal contacts in CdTe/CdS thin-film solar cells for the formation of low resistance back contacts. Different metals (Au, Ni, Co) have been investigated as the contact material to the ZnTe layer. The effects of Cu concentration, ZnTe:Cu layer thickness, and ZnTe post-deposition annealing temperature on the cell performances have been investigated. The authors found that different metal contacts on the ZnTe layer lead to different doping densities in the CdTe layer and different open-circuit photovoltages of the solar cells. The possible formation of a back contactmore »« less
Dependence of the efficiency of a CdS/CdTe solar cell on the absorbing layer's thickness

Journal Article Kosyachenko, L. A., E-mail: lakos@chv.ukrpack.net ; Savchuk, A I ; Grushko, E V - Semiconductors

On the basis of the continuity equation, the spatial distribution of photogenerated excess electrons in the neutral region of the CdTe layer in a CdS/CdTe heterostructure is analyzed taking into account recombination at the rear surface of the layer. It is demonstrated that, owing to diffusion, excess electrons penetrate deep into the CdTe layer at distances far exceeding the effective penetration length for solar radiation. Calculations of the short-circuit current indicate that, for electron lifetimes of 10{sup -10}-10{sup -9} s, typical of thin-film CdS/CdTe solar cells, recombination losses are insignificant if the CdTe layer's thickness amounts to 3-4 {mu}m butmore »« less

Processing issues for thin film CdTe/CdS solar cells

Journal Article McCandless, B E ; Birkmire, R W ; Jensen, D G ; ... - AIP Conference Proceedings

Processing options addressing critical issues associated with fabrication of high efficiency thin film CdTe/CdS solar cells are presented. Particular focus is given to methods for: minimizing CdS loss during CdCl{sub 2} heat treatment; obtaining high open circuit voltages; obtaining spatially uniform properties; and forming ohmic contacts. Data is presented for cells deposited by physical vapor deposition (PVD) which demonstrates that CdS loss can be overcome by use of CdTe{sub 1{minus}x}S{sub x} absorber layers and by controlling the delivery of CdCl{sub 2} vapor species during heat treatment. The CdCl{sub 2} vapor treatments are shown to produce residue-free surfaces and uniform filmmore »« less
