Cs2CO3was used as surface modification material for organic–inorganic perovskite solar cells to retard the charge recombination at the mp-TiO2surface, leading to enhanced performance.
The light beam induced current (LBIC) method was adopted to nondestructively map the photoresponse of real planar organic–inorganic hybrid perovskite solar cells (PSCs).
Although the power conversion efficiency (PCE) of organic–inorganic hybrid perovskite solar cells (PSCs) is comparable to those of commercial solar cells, a challenging problem of instability hampers their further commercialization.
Controlling the grain size of the organic–inorganic perovskite thin films using thiourea additives now crossing 2 μm size with >20% power conversion efficiency.
