A low-temperature silver paste is a screen-printable conductive ink cured near 200 °C, used for metallizing silicon heterojunction solar cells whose amorphous layers tolerate little heat.
Luminescent downshifting
Luminescent downshifting (LDS) is an optical technique for solar cells in which a luminescent layer absorbs UV and blue light and re-emits it where the cell converts more efficiently.
Luminescent solar concentrator
A luminescent solar concentrator is a photonic device, first proposed in 1976, that uses luminophore-doped plates to guide sunlight to edge-mounted photovoltaic cells, mainly for building windows.
