A novel one-step laser process for the rapid fabrication of mesoscopic perovskite solar cells
With the rapid increase of efﬁciency beyond 22%, perovskite solar cells (PSCs) have become one of the hottest topics in the field of PV research. Mesoscopic metal oxide scaffold is considered as a benchmark structure for high performance PSCs with highest efficiency and stability. However, a major drawback is the involvement of time-consuming and high-temperature processes in its fabrication. Researchers at The University of Manchester have recently demonstrated a novel one-step laser process to rapidly fabricate mesoscopic structured PSCs in ambient atmosphere, without thermally damaging ITO layer and the glass substrate.
