Origins of Reverse Bias Currents in a Typical BPW34 Photodiode
Bayhan, Habibe; Özden, Şadan (Scientific Technical Research Council Turkey-Tubitak, 2005)Measurements of the dark reverse current in a typical BPW34 silicon photodiode have been made in the temperature range 100-300 K at various reverse bias voltages ranging from 0 to 60 V. Various transport models have been ... -
Tunneling-Enhanced Recombination in Polycrystalline CdS/CdTe Solar Cells
Bayhan, Habibe (Scientific Technical Research Council Turkey-Tubitak, 2006)The dominant dark current transport mechanism in as-grown and CdCl2 processed CdS/CdTe heterojunction solar cells for temperatures below 300 K was investigated. The current-voltage properties of these solar cells is explained ...
