This is the first report of using anatase TiO2 nanosheets with exposed (001) facets in a high‐efficiency PbS quantum dot/TiO2 heterojunction solar cell. The TiO2 nanosheets have higher conduction band, and surface energy compared to normal anatase (101) TiO2 nanoparticles. This PbS QD/TiO2 heterojunction solar cell produces power conversion efficiency of 4.7% which is one of the highest reported in...
We have designed and synthesized highly efficient organic sensitizers with a planar thienothiophene–vinylene–thienothiophene linker. Under standard global AM 1.5 solar conditions, the JK‐113‐sensitized cell gave a short circuit photocurrent density (Jsc) of 17.61 mA cm−2, an open‐circuit voltage (Voc) of 0.71 V, and a fill factor (FF) of 72 %, corresponding to an overall conversion efficiency (η)...
