ON THE PROPERTIES OF(CD, PB) S-SB SEMICONDUCTOR ELECTROLYTE SOLAR-CELLS/

The (Cd, Pb)S:Sb electrode and sulphide/polysulphide electrolyte based photoelectrochemical cells have been evaluated through the electrical and optical properties. The range of Sb-doping concentration used was from 0 to 10 mol% The I-V and C-V characteristics in dark, power outp ut curves under 22.4 mW/cm(2) illumination and photo-response measurem ents have been analysed with a special emphasis given to the antimony doping concentration. It has been observed that the cell performance e xamined in terms of the various performance parameters (I-ph, V-ph, R- s, R-sh, ff%, n %, n(d), n(L), V-fb Phi(B) etc.) is optimum at 1 mol% Sb-doping concentration in (Cd, Pb)S:Sb photo-electrode. These observa tions have been correlated to the modified film properties.
