Recently, intensive research efforts into the development of both photo-active materials, processing techniques, interface engineering, and device architecture have led to a remarkable improvement in power conversion efficiencies, approaching almost 20% for organic photovoltaics (OPVs) and exceeding 26% for perovskite solar cells (PSCs). Current research interests are expanding from academic to industrial viewpoints to improve device stability and compatibility with large-scale printing processes. Here, both academic and industrial issues are reviewed by highlighting historically monumental research results and recent state-of-the-art progress in the development of printed modules of OPVs and PSCs. Moreover, perspectives on five core technologies that affect the realization of the practical use of these photovoltaics are presented, including device efficiency, device stability, flexible and transparent electrode, module designs, and printing techniques.
