Abstract :
An alternative model for glass/CG/CdS/CdTe/metal solar cell is presented. Using guidelines based on this new model, the authors have fabricated improved devices producing open-circuit voltage (V/sub oc/) values over 600 mV, fill factor (FF) values over 0.60 and the short-circuit current density (J/sub sc/) values over 60 mAcm/sup -2/ for best devices. Although V/sub oc/ and FF could be further improved, the remarkable improvement of J/sub sc/ indicates the possibility of further development of CdS/CdTe solar cell. Positive effects of n-type doping of CdTe with iodine and MlS type electrical contacts are presented.
