Thermal processing is critical in preparing the functional layers for perovskite solar cells (PSCs), such as metal oxides (TiO2 and SnO2) electron transport layers (ETLs), and perovskite layer. The conventional thermal processing method using a furnace or hotplate with a time-consuming heating and cooling period impedes the possibility of achieving a rapid and in-line production for the commercialization of PSCs.
Laser processing is an advanced manufacturing method that owns various advantages over conventional thermal processing, including being rapid, scalable, contact-free, area-selective, and causing minimal thermal damage.
In this presentation, I will summarize our recent studies carried out at The University of Manchester using lasers to fabricate a range of ETLs, including compact and mesoporous TiO2, Ta-doped TiO2, SnO2, and ZnO for efficient rigid and flexible PSCs [1-3]. In addition, I will introduce our latest study using the laser-induced graphene decorated with the NiOx nanoparticles as the back electrode for hole-transport-layer-free PSCs.
The studies presented in this presentation were supported by the Engineering and Physical Sciences Research Council (EPSRC) funding under grant no.EP/V008188/1.
