用熔盐包裹的CuI晶体控制多孔着色的TiO2层的孔填充，并用氧化锌缩颈改善TiO2层，制备了稳定性提高的高效固体太阳电池(TiO2DYE/CuI)。熔融盐控制CuI晶体的生长，并对CuI纳米晶体起到保护层的作用，与导电性更强的氧化锌的缩颈改善了二氧化钛颗粒之间的电接触，两者都有助于改善电池性能。连续光照约2周，细胞效率高达3.8%，稳定性提高。
dA highly efficient solid-state solar cell (TiO2/dye/CuI) with improved stability was fabricated by controlling the pore filling of the porous dyed TiO2 layer with molten salt capped CuI crystals and improving the TiO2 by necking with ZnO. The molten salt controls the CuI crystal growth and acts as a protective coating for CuI nanocrystals, and necking with the more conductive ZnO improves electrical contact between TiO2 particles, both contributing to improved cell performance. Cells achieved efficiency as high as 3.8% with improved stability under continuous illumination for about 2 weeks.
