- •
A novel and green solvent of 1-Ethyl-2-pyrrolidone (NEP) was used to construct high-quality perovskite CH3NH3PbI3 thin film.
- •
The CH3NH3PbI3 grain with different sizes ranged from hundreds of nanometers to several micrometers can be obtained.
- •
Planar-structured perovskite CH3NH3PbI3 solar cells using NEP as solvent achieves a power conversion efficiency of 10.2%.
