The dye sensitized solar cell (DSSC) operation depends on a liquid electrolyte. To achieve better performance, the liquid should be replaced with a solid or gel electrolyte, e.g., polymers. Here, we demonstrate initiated chemical vapor deposition as an effective liquid-free means for in situ polymerization and pore filling. We achieve complete pore filling of 12 μm thick titania resulting in enhanced cell performance that is attributed to reduced charge recombination at the electrolyte-electrode interface.
染料敏化太阳能电池（DSSC）的工作依赖于液体电解质。为了获得更好的性能，可以用固体或凝胶电解质代替液体电解质，例如聚合物。在这里，我们证明引发化学气相沉积是一种有效的无液体原位聚合和孔填充方法。我们实现了 12μm 厚的二氧化钛的完全孔填充，从而提高了电池性能，这归因于在电解质-电极界面处减少了电荷复合。
