Promise of commercialization: Carbon materials for low-cost perovskite solar cells |
(color online) Device structure and energy-level diagram: (a) schematics of the whole device: FTO glass/compact TiO2 layer/mesoporous TiO2/CH3NH3PbI3 capping layer/CuPc/carbon and (b) the corresponding energy level diagram. Fabrication process flow for the instant inkjet printing of the C/CH3NH3PbI3 planar perovskite solar cells. For comparison, a different strategy was used to convert PbI2 into CH3NH3PbI3 using separate step 3 and step 4. Reprinted from Ref. [ |
