Charge Carrier Lifetime

We compare SPV technique with µ−PCD for the determination of recombination activity of copper precipitates in p-Si. The copper precipitates were formed in bulk silicon through illumination at room temperature. We observed that the recombination activities of copper precipitates measured with SPV are higher than the ones measured with µ−PCD technique. However, it seems that the copper detection sensitivity is about the same with SPV and µ−PCD techniques.

Unusually long charge carrier lifetime in methylammonium lead halide perovskites is a result of the Rashba-split indirect bandgap. At high pressure the bandgap becomes purely direct, with shorter carrier lifetime and higher radiative efficiency.
