Upconversion and Downconversion Processes for Photovoltaics

2018
The main efficiency losses of all single threshold solar cells resulting in energy-conversion efficiencies fundamentally constrained by Shockley–Queisser (S-Q) limits to practical values below 30% arises mainly from the photons that are not absorbed due to energy less than the threshold (so-called sub-bandgap or transmission losses) and due to the ...
