High-efficiency organic–silicon heterojunction solar cells with high work function PEDOT:F-based hole-selective contacts†
Efficient and stable organic–silicon heterojunction solar cells are highly desirable. In this work, solution-processed poly(3,4-ethylenedioxythiophene):perfluorinated sulfonic acid (PEDOT:F) was investigated as a hole-selective contact for crystalline silicon (c-Si) solar cells. The optoelectronic properties, surface passivation and contact resistivity of PEDOT:F-based contacts on c-Si were investigated and optimized. The performance of the PEDOT:F-based hole-selective contact was verified on p-type c-Si solar cells. A record efficiency of 21.6% was achieved for an organic–silicon heterojunction solar cell featuring a full-area Al2O3/PEDOT:F/Ag rear contact for hole collection. The device displayed excellent environmental stability, retaining 85% of its initial efficiency after exposure to air for 120 days.
