Optical properties of solar cells with SiO2 and silicon rich oxide with silicon nanoparticles

A study of comparison of the optical characteristics of silicon solar cells with a layer of silicon oxide (SiO2) deposited by SILOX, and silicon solar cells covered with a silicon rich oxide (SRO) film obtained by LPCVD containing silicon nanoparticles (Si-nps) was made. To increase the density of n...

Descripción
Sumario:A study of comparison of the optical characteristics of silicon solar cells with a layer of silicon oxide (SiO2) deposited by SILOX, and silicon solar cells covered with a silicon rich oxide (SRO) film obtained by LPCVD containing silicon nanoparticles (Si-nps) was made. To increase the density of nanoparticles and thus improve the red photoluminescence and the photocurrent, the SRO films were annealed at 1100 °C. Photoluminescence spectra and atomic force microscopy measurements of the silicon rich oxide films are presented and discussed, as well as current-voltage curves and spectral response of the fabricated solar cells.
