Enhanced ultraviolet responses in thin-film InGaP solar cells by down-shifting

Author affiliations

Abstract

Layers of poly(methyl methacrylate) doped with the Eu complex Eu(DPEPO)(hfac)3 (EuDH) provide a means for down-shifting incident ultraviolet (UV) light into the visible range, with beneficial effects on the performance of solar cells, as demonstrated with thin-film InGaP devices formed by epitaxial liftoff. Experimental and computational results establish important aspects of gain and loss mechanisms in the UV range. Measurements show that InGaP cells with coatings of EuDH doped PMMA exhibit enhanced currents (8.68 mA cm−2) and power conversion efficiencies (9.48%), both due to increased responses at wavelengths between 300–360 nm.
