Suppression of the thermal quenching of photoluminescence in irradiated silicon heterojunction solar cells

Autor: Pere Roca i Cabarrocas, Alice Defresne, Olivier Plantevin

Publikováno v: physica status solidi (a). 213:1964-1968

We report on the decrease in photoluminescence (PL) intensity with the increase of the sample temperature (thermal quenching) in crystalline silicon and its suppression after ion irradiation. The crystalline silicon surface was passivated with intrin
