In silicon (Si)/organic (heterojunction) solar cells, the introduction of a textured structure on the Si surface is an effective approach to increase their power conversion efficiency. In the fabrication of such cells, it is critical to improve the adhesion between the silicon with the textured structure and the organic polymer, to increase the absorption efficiency of sunlight, and to suppress the recombination during carrier transport. In this study, we discuss the impact of the improvement of Si/polymer interface adhesion by APTES modification and the suppression of carrier recombination by the introduction of a hole blocking layer on the photovoltaic performance of boron-doped Si nanoparticles/textured Si/organic polymer solar cells.
