Topologically interpenetrating 3D charge injection-separation mechanism: enables preparation of high-performance PV modules via all-wet process

Against the backdrop of China’s “Dual Carbon” strategy, developing low-cost, high-performance printable mesoscopic perovskite solar cells (p-MPSCs) is pivotal to upgrading the photovoltaic industry. Founded in 2016, WonderSolar is dedicated to the R&D and industrialization of printable mesoscopic perovskite photovoltaic technology, with its core technology stemming from Huazhong University of Science and Technology (HUST). It runs a 400 MW production line, and its demonstration power station has operated stably for over 5 years. Leveraging the topologically interpenetrating 3D charge injection-separation mechanism and oxide semiconductor modulation theory, the WonderSolar team has achieved a world-leading certified active area power conversion efficiency (PCE) of over 26% for 52.2 cm² p-MPSC modules.
