High bandgap perovskites for efficient indoor light harvesting

High-bandgap perovskite solar cells are suitable for indoor applications owing to their efficient absorption of the common LED lighting spectrum. We explore how indoor irradiance affects the light harvesting performance, discuss the importance of high VOC for low light operation and demonstrate efficiency of 29% in perovskite solar cell with CH3NH3Pb(I0.8,Br0.2)3 absorber at 200 – 500 lx, typical for indoor lighting.
