Efficient, large-area scalable Perovskite-Si and Perovskite-CIGS tandem solar modules

摘要

. By using a low-loss module design and optimized light coupling, we demonstrate perovskite-Si and perovskite-CIGS tandem solar modules which outperform the stand-alone devices on the large area, representing a key milestone for perovskite-based tandem photovoltaics. Moreover, the tandem solar module architecture is compatible with industrially scalable fabrication techniques, thus opening the route towards production of high-performance largearea perovskite-based tandem solar modules.
