Abstract

In2O3 thin films have been deposited on silicon substrate by chemical spray pyrolysis. These films show high transparency in the visible and near-IR regions. Photoresponse of In2O3/c-Si isotype hetero-photodiode without post-deposition heat treatment has been investigated in the visible and infrared regions. Peak response situated at 600nm was observed. External quantum efficiency was 32% at peak response. C-V measurements revealed that the junction was abrupt type and built-in potential around 1eV has been obtained.

Abstract

In the present work, the energy band diagram of p-PbTe/n-Si heterojunctions made by thermal evaporation of a polycrystalline PbTe layer deposited on a monocrystalline Silicon substrate is constructed. Based on I-V and C-V measurements, the band offsets ΔEC and ΔEV are found experimentally to be 270mV and 610mV respectively at 300K.

Abstract

The depth dependence of photoluminescence from as grown and CdCl2 treated polycrystalline CdSe/CdTe solar cells has been compared using a bevel etch technique. It has been found that the three emission bands observed at 1.59eV, 1.55eV and 1.45eV all became more intense after the treatment, with the emission at 1.55eV near the CdSe/CdTe interface being the most affected.
