Abstract


We theoretically and experimentally determined the optimized

film properties of luminescent down-shifting (LDS)

layers for thin film solar cells. Based on the predictions from

an adapted optical model, we coated thick (300–500 mm) and

efficient luminescent down-shifting layers from environmentally

friendly solvents and industrially scalable inks. LDS

layers consisted of polyvinyl butyral (PVB) as binder and organic

luminescent dyes as UV-converters. The luminescence

quantum yields of the dyes were studied in solution (benzyl

alcohol) and for solid thick films. Our data shows that the

studied dyes retain luminescent efficiencies of approximately

90% in the solid state when processed from solution. We further

apply the produced layers onto copper indium gallium

diselenide (CIGS) solar cells to verify the theoretical predictions

for enhancing the external quantum efficiency (EQE)

in the UV region. For the best converters a remarkable enhancement

of the EQE from 9% to 52% was recorded at

380 nm. These findings underline that printed LDS layers

indeed have the potential to enhance the efficiency and the

light harvesting capabilities of industrially relevant photovoltaic

modules.
