On the bright side : A solution‐based strategy was developed for in situ synthesis and film deposition of Cu 2 ZnSnSe 4 nanocrystal films (samples a–d). The obtained Cu 2 ZnSnSe 4 nanocrystal films can be used as an effective counter‐electrode (CE) material to replace Pt, and yield low‐cost, high‐efficiency dye‐sensitized solar cells (DSSCs). The assembled solar cell devices exhibit an efficiency of 7.82 % under 1 sun irradiation (see figure).
