Light trapping efficiency comparison of Si solar cell textures using spectral photoluminescence

Barugkin, Chog; Allen, Thomas; Chong, Teck K; White, Thomas; Weber, Klaus J; Catchpole, Kylie


The band-to-band absorption enhancement due to various types of light trapping structures is studied experimentally with photoluminescence (PL) on monocrystalline silicon wafers. Four basic light trapping structures are examined: reactive ion etched texture (RIE), metal-assisted etched texture (MET), random pyramid texture (RAN) and plasmonic Ag nanoparticles with a diffusive reflector (Ag/DR). We also compare two novel combined structures of front side RIE/rear side RAN and front side RIE/rear...[Show more]
