High-efficiency ({eta} = 39.6%, AM 1.5D) cascade of photoconverters in solar splitting systems
- Russian Academy of Sciences, Ioffe Physical Technical Institute (Russian Federation)
A concentrator photovoltaic module with spectral splitting of solar radiation is developed. The module is based on a Fresnel lens and two dichroic filters. Solar cells based on AlGaAs and GaAs are grown by low-temperature liquid-phase epitaxy. GaSb photoconverters are fabricated by zinc gas-phase diffusion into a base epitaxial layer or an n-type GaSb substrate. The total efficiency of three solar cells developed for the spectral splitting module reached 39.6% (AM 1.5D spectrum).
