Abstract

Abstract: An organic/amorphous silicon(a-Si) hybrid tandem solar cell has been fabricated using poly(diketopyrrolopyrrole-terthiophene) (PDPP3T) as the active layer in organic solar cell. High external quantum efficiency (8.32%) and a fill factor (FF) of 0.76 are achieved under AM 1.5 illumination. The Voc of the tandem solar cells are almost equivalent to the sum of the sub-cells. The high performance of the device results from the complementary absorption spectra of two sub-cells. The SEM cross-sectional image of the device has been analysed and the distributions of the component elements can be clearly observed.
