NANO PHASED MATERIALS AND THIN FILM HETEROSTRUCTURES FOR EFFICIENT SOLAR ENERGY CONVERSION
Khandekar Ganesh Vishnu, Dr. Premlata Pandit
Abstract
Solar cells with n-type windows made of RF magnetron-sputtered CdS and heterojunction PbS
quantum dot solar cells. The open-circuit voltage of these solar cells is significantly higher than that
of previously reported PbS-QD cells. At 1.57 eV, the bandgap energy of this device may be derived
from measurements of the optimally thinned CdS layer and the optimised PbS QD diameter, both of
which we have measured. We achieved a short circuit current of 12 mA/cm2
, an open circuit
voltage of 0.65 V, and an efficiency of 3.3% under simulated AM1.5 G light.
