Zn-doped SnO2 nanocrystals as efficient DSSC photoanode material and remarkable photocurrent enhancement by interface modification

Zn-doped SnO2 nanocrystals with different doping concentrations were synthesized and the nanocrystal photoanode based DSSC achieved a PCE of 2.07% with a high Voc (0.67 V). TiCl4 modification of the photoanode greatly improves the charge injection efficiency and charge collection efficiency and the...
