Organic-inorganic hybrid perovskites have emerged as a promising high-performance, cost-effective solar cell technology. However, most of the best reported efficiencies have been obtained on small active-area devices (~0.1 cm2). To move forward this technology towards commercialization, it is important to develop up-scaling processes with high performance and stability [1]. At OIST, a team of researchers in the Energy Materials and Surface Sciences Unit have been making concerted efforts to develop processes aiming at high PCE, high-throughput, and minimum batch-to-batch variation, and compatible with large-area perovskite solar cells and modules. We will present our progress to use chemical vapor deposition [2-5] and spray coating [6] to fabricate perovskite solar cells and modules. Also, we will introduce a novel methylamine gas induced crystallization process [7, 8], which provides valuable insights into the formation of perovskite films.
