摘要：

Cd2SnO4 thin films were investigated from a materials point of view as well as from an application. point of view through their incorporation into CdTe based solar cells. Cd2SnO4 was deposited by co-sputtering from CdO and SnO2 targets. The lowest resistivity achieved was 2.01 X 10(-4) Omega-cm with. a mobility of 29.2 cm(2)/V/s and a carrier concentration of 8.47 X 10(20) cm(-3).. For this same sample the average transmission was. over 90% over the visible and near IR spectrum (400-900nm). When Cd2SnO4 were used as part of the front contact in thin film CdTe solar cells V-OC's over 840 mV, J(SC)'s over 23 mA/cm(2), and ff's over 68.0% were obtained with the best to-date efficiency being 14.0%.
