Perovskite-based mesoscopic and other hybrid solar cells have attracted enormous attention from academic and industrial researchers due to their high power conversion efficiency, low cost, and high performance under diffuse and non-ideal light conditions. However, despite these promising aspects, there are still a number of challenges which need to be resolved, such as process scale-up, in order to achieve commercial viability of perovskite solar cells.
Most academic laboratory cells use ALD, spray pyrolysis, spin coating or vacuum evaporation as the deposition techniques, which would be cumbersome or expensive at the industrial level. Dyesol has developed a series of scalable processes and techniques for scale-up of perovskite solar cells, including screen printing compact TiO2 blocking layers, screen printing meso-porous TiO2 scaffold films (~350 nm), slot die deposition of methylammonium lead iodide and slot die deposition of hole transport material. All these techniques gave uniform and consistent devices with promising performance. Scale-up to larger area modules will be discussed and performance data presented.
Dyesol investigated the factors that influence the stability of standard perovskite solar cells and carbon/perovskite solar cells, including: storage environment, temperature, light soaking spectrum, and encapsulation. Preliminary results will be presented and discussed in terms of degradation mechanisms.
