PHOTOVOLTAICS

Utilizing hot electrons

Nature Energyvolume 3pages170171 (2018) | Download Citation

In current solar cells, any photon energy exceeding the semiconductor bandgap is lost before being collected, limiting the cell performance. Hot carrier solar cells could avoid these losses. Now, a detailed experimental study and analysis shows that this strategy could lead to an improvement of the photoconversion efficiency in practice.
