Abstract

Organic/silicon hybrid solar cells have attracted extensive attention owing to their low cost and simple manufacturing process. However, theoretical simulations indicate that the efficiency of organic/silicon hybrid solar cells should exceed 20%. This study demonstrates phosphorus and selenium co-doped WO3 nanoparticles used for heterojunction solar cell (HSC) modification and theoretically elaborates the effects of these doping elements. The doped WO3 nanoparticles are added into poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) films to optimize the physical properties and qualities of the organic layer. The admixture of P/Se-WOx greatly improves the open-circuit voltage and fill factor of Si/PEDOT:PSS solar cell devices. In the hole transport layer (HTL)-based device, the P/Se-WOx hybrid PEDOT:PSS HTL yields a power conversion efficiency up to 13.64%, which is substantially higher than those of previously reported undoped and doped devices. The generated W5+ in optimized WO3 further indicates that the VI B group elements, such as W or Mo with 5+ state ions, positively influence the HSC performance and would greatly benefit the photovoltaic industry.
