A hybrid solar cell composed of a crystalline semiconductor and polymer film has attracted much attention due to numerous advantages, such as high mobility, long lifetime, and the aqueous solution processing. Recently, the power conversion efficiency (PCE) of the hybrid solar cell of silicon (Si) wafer and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is reported to be higher than that of a commercial amorphous Si solar cell. Here in the Si/PEDOT:PSS hybrid solar cell was prepared using dimethyl sulfoxide (DMSO) as an additive to the PEDOT:PSS solution. The PCE was increased up to 10-fold by the addition of DMSO at a concentration of 5 wt%. Results from grazing-incidence X-ray diffraction, atomic force microscopy, and Raman spectroscopy indicated the 10-fold enhancement was controlled by the nanostructure of the PEDOT:PSS film. The enhanced performance was attributed to (i) an increase of π–π stacking, (ii) shortened distances between π–π planes, (iii) an increase in the quinoid structure of PEDOT, and (iv) reduced PEDOT:PSS particle size. The PCE was also enhanced by a transparent cathode of colloidal Ag nanowires and through the use of a vacuum-free process for preparation of the PEDOT:PSS film.

PEDOT：PSS薄膜纳米结构控制的Si / PEDOT：PSS混合太阳能电池的性能
由晶体半导体和聚合物膜组成的混合太阳能电池由于具有许多优点，例如高迁移率，长寿命和水溶液加工而备受关注。最近，据报道硅（Si）晶片和聚（3,4-乙撑二氧噻吩）-聚（苯乙烯磺酸盐）（PEDOT：PSS）的混合太阳能电池的功率转换效率（PCE）高于商业非晶硅。硅太阳能电池。在这里，在Si / PEDOT：PSS中，使用二甲基亚砜（DMSO）作为PEDOT：PSS溶液的添加剂来制备混合太阳能电池。通过以5重量％的浓度添加DMSO，PCE增加至10倍。掠入射X射线衍射，原子力显微镜和拉曼光谱的结果表明，PEDOT的纳米结构控制了10倍的增强：PSS胶卷。性能的提高归因于（i）π-π堆积的增加，（ii）π-π平面之间的距离缩短，（iii）PEDOT的醌型结构增加，以及（iv）PEDOT：PSS粒径减小。胶态银纳米线的透明阴极以及通过使用无真空工艺制备PEDOT：PSS薄膜也增强了PCE。
