Micro-photoluminescence spectroscopy on heavily-doped layers of silicon solar cells

Nguyen, Hieu T.; Yan, Di; Wang, Fan; Zheng, Peiting; Han, Young; Macdonald, Daniel


We report and explain the photoluminescence spectra emitted from silicon solar cells with heavily-doped layers at the surface. A micro-photoluminescence spectroscopy system is employed to investigate the total spectrum emitted from both the heavily-doped layer and the silicon substrate with micron-scale spatial resolution. The two regions of the device give rise to separate photoluminescence peaks, due to band-gap narrowing effects in the highly-doped layer. Two key parameters, the absorption...[Show more]
