The application of luminescent down shifting (LDS) layers as alternative UV filters for CH3NH3PbI3(1-x)Cl3x perovskite solar cell (PSC) devices is reported. A combination of photo-absorption measurements and of device decay measurements during light soaking are used to verify the stability. The application of a UV filter or LDS layer was able to significantly retard photo-induced degradation with...
We measure the diurnal dependence of the operating characteristics of tetraphenyldibenzoperiflanthene (DBP):C70 planar-mixed heterojunction small-molecule organic photovoltaic (OPV) cells with 2,2′,2″-(1,3,5-benzenitryl tris-[1-phenyl-1H-benzimidazole] (TPBi):C70 electron-filtering cathode buffer layers. Over the course of a day, efficiency gradually increases as a result of a concomitant increase...
