Are selenium solar cells a top cell for tandem photovoltaics?
T. H. Youngman, R. Nielsen, A. Crovetto, B. Seger, O. Hansen, I. Chorkendorff, P. C. K. Vesborg,Semitransparent selenium solar cells as a top cell for tandem photovoltaics.
Can a multi-junction photovoltaic cell have a selenium interlayer?
To obtain even higher efficiencies of over 40%, both the top and bottom layers can be multi-junction solar cells with the selenium layer sandwiched in between. The resultant high performance multi-junction photovoltaic cell with the selenium interlayer provides more power per unit area while utilizing a low-cost silicon-based substrate.
Why is selenium a good absorber for solar cells?
Selenium shows high absorption coefficient and mobility, making it an attractive absorber for high bandgap thin film solar cells. Moreover, the simplicity of a single element absorber, its low-temperature processing, and intrinsic environmental stability enable the utilization of selenium in extremely cheap and scalable solar cells.
