Photocarrier lifetime and recombination losses in photovoltaic systems

Abstract

To the Editor — The photocarrier lifetime is commonly employed to describe the performance of photovoltaic and photodetecting devices fabricated from crystalline or non-crystalline materials. Numerous studies have obtained photocarrier lifetimes from transient decay signals in a multitude of non-crystalline systems, such as dye-sensitized solar cells, organic donor–acceptor blends, perovskites, nanoparticles,…
