Carbon-based perovskite solar cells by screen printing with preheating

Carbon-based perovskite solar cells were manufactured by the screen-printing method using a triple mesoscopic layer of TiO, ZrO and carbon. The perovskite solution was infiltrated at the TiO/ZrO porous interface through the printed carbon layer on top of the ZrO. Using a simple preheating of the substrates and the perovskite solution, a film deposited in air can be obtained. Using this method, an air-processed CPSC made under a humid atmosphere with 55% RH achieved a PCE of 10.35%
