STUDIES ON N-CDS P-SNS THIN-FILM HETEROJUNCTION SOLAR-CELLS/

Polycrystalline thin film heterojunction solar cells with the configur ation glass/Sb:TO/n-CdS/p-SnS/Ag were fabricated using vacuum evaporat ed CdS as window and sprayed SnS films as an absorber layer. The physi cal properties of the individual layers were discussed. The photovolta ic properties of the device were evaluated by studying the illuminated current-voltage characteristics and with the help of spectral respons e measurements. The cells showed a maximum conversion efficiency of ab out 0.7 % with an average spectral response of 65 %.
