由硅（Si）和聚合物薄膜组成的太阳能电池由于其高性能和易于使用水溶液制备而受到广泛关注。虽然已经进行了大量的研究以进一步提高其性能，但从物理化学的角度来看，实现这一目标所需的因素尚未完全了解。在这里，我们展示了添加剂对使用六种不同添加剂的Si/聚（3，4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）太阳能电池的性能的影响。通过改变添加剂和导电循环伏安法、电导率和二维掠入射角X射线衍射测量，研究了太阳能电池性能、电性能和聚合物膜结构之间的关系。添加剂分子的偶极矩被确定为提高Si/PEDOT：PSS太阳电池性能的关键因素。特别是具有较高偶极矩的添加剂。
Solar cells composed of silicon (Si) and polymer films have attracted much attention because of their high performance and facile preparation using aqueous solutions. Although a large amount of research has been carried out to further improve their performance, the factors required to achieve this are not yet fully understood from the perspective of physical chemistry. Here, we show the effect of additives on the performance of Si/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) solar cells using six different additives. The relationships among the solar cell performance, electrical properties, and the structure of the polymer film are examined by changing the additive and conducting cyclic voltammetry, electric conductivity, and two-dimensional grazing incidence angle X-ray diffraction measurements. The dipole moment of the additive molecule was determined to be a key factor for improving the performance of Si/PEDOT:PSS solar cells. In particular, an additive with a higher dipole momen...
