| Sumario: | CdS/CdTe solar cells were fabricated without antireflection coatings by successive
growth without intermediate processing from the close space sublimation of CdS and CdTe
thin layers on conductive and transparent SnO2/glass substrates. At 300 K and 100 mW/cm2
the following best photoelectric parameters were obtained: Isc= (18-19)mA/cm2 and
Voc=(0,80-0,82)V. The conversion efficiency is around 10%. The quantum efficiency (QE) in
the 510 nm and 845 nm range of wavelengths is on the order of 80-85%. The minimodule
fabricated on the basis of the CdTe cells shows power of 0.45 W, corresponding to a voltage
of 3 V, and current of 150 mA. |
