The interest to Perovskite Solar Cells is drastically increased in the last few years. High power conversion efficiency and low-cost potential are making Perovskite PV a very promising candidate for future applications. Low-cost potential is based on the cheap earth-abundant materials and possibility of solution R2R processing. In order to develop stable and reproducible vacuum-free R2R process for all the layers in the device stack the following topics are intensively investigated: (i) optimization of generic device stack, providing high efficiency and long operational stability; (ii) cheap and non-vacuum processes for the electrode materials; (iii) optimization of slot die coating process for most of the layers in the device stack; (iv) reduction of annealing time and temperature via alternative annealing methods, namely flash and infrared annealing; (v) development of encapsulation strategy for perovskite modules, etc. Flexibility, low cost and high efficiency open new strategies for the further application of Perovskite PV, making this technology competitive with conventional PV technologies. Motivated by future applications we have performed the modeling of optimum module design with maximum efficiency and highest geometrical fill factor. Using slot die coating process and laser ablation, to make interconnection in the modules, we are working on the development of the technology which will be ready for industrialization.
