Low-temperature solution-processed Zn-doped SnO2 photoanodes: enhancements in charge collection efficiency and mobility

An increase in charge collection efficiency and charge mobility from 78 to 89% and 0.02 to 0.04 cm2 V−1 s−1, respectively, in low-temperature solution-processed Zn-doped SnO2 photoanodes resulted in a two-fold enhancement in power conversion efficiency (PCE) as compared to Zn free SnO2 photoanodes in dye-sensitized solar cells (DSSCs).
