Newly emerging solar cell technologies such as organic photovoltaics and perovskite photovoltaics are widely expected to play an important role in providing society with significant amounts of inexpensive, environmentally friendly and renewable electricity in the years to come. These two promising solar cell technologies are in the “scale up” stage as they attempt to bridge the gap between academic research and commercial viability in the marketplace. Finding and understanding efficient ways to fabricate them over large areas is critically important to their survival and success today. Spray deposition holds great promise for providing the inexpensive and scalable fabrication method needed for producing certain layers for these cells, in particular for transparent electrodes. Here we detail a state-of-the-art spray deposition platform/research tool for depositing thin, uniform films of nanoparticles over large areas at extremely low cost. We describe silver nanowire transparent conductive films and p-type hole transport layers of sprayed carbon nanotubes deposited directly onto perovskite solar cells.
