Carbon-based perovskite solar cells by screen printing with preheating

Peruvian Workshop on Solar Energy (JOPES 2019) 8–10 May 2019, Lima (Perú).Carbon-based perovskite solar cells were manufactured by the screen-printing method using a triple mesoscopic layer of TiO2, ZrO2 and carbon. The perovskite solution was infiltrated at the TiO2/ZrO2 porous interface through the printed carbon layer on top of the ZrO2. 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%.One of the authors (V.M.) wish to acknowledge the scholarship by FONDECYT within the Doctoral Program in Sciences with mention in Energy from the National University of Engineering.
