Abstract

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) is investigated as 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 are investigated and optimized. The performance of PEDOT:F-based hole-selective contact is verified on p-type c-Si solar cells. A record efficiency of 21.6% is achieved for organic-silicon heterojunction solar cell, featuring a full-area Al2O3/PEDOT:F rear contact for hole collection. The device displays excellent environmental stability, retaining 85% of its initial efficiency after exposure in the air for 120 days.
