Photovoltaics in heterojunctions, particularly CdS/Cu/sub 2/Sq. (Direct solar energy conversion for large-scale terrestrial use). Technical report
An overview of the operation of the Cu/sub 2/S-CdS solar cell is given in terms of heterojunction theory. The factors determining the open circuit voltage, fill factor, and short circuit current are treated. The short circuit current's dependence on the mode of operation of the cell, on the Cu/sub 2/S parameters: absorption coefficient, diffusion length, thickness, grain size, drift fields, and surface recombination and on the CdS parameters: space charge field, mobility, and interface recombination velocity is discussed. The dependence on the open circuit voltage on the difference in work functions between Cu/sub 2/S and CdS and the mechanisms for the dark diode current is shown. The present properties on the Cu/sub 2/S-CdS cell are explained and suggestions for obtaining higher open circuit voltage are given. (GRA)
