In August 2024, following the successful entry into the final debugging phase of Rollshine Photoelectric' 10MW flexible lightweight perovskite photovoltaic module pilot production line, a month of intensive research culminated in a significant technological breakthrough. Certified by the South China National Center for Metrology, Rollshine's 30cm×40cm single-junction flexible perovskite photovoltaic modules achieved a world-record certified average efficiency of 18.63% over the total active area-the highest reported value for flexible perovskite PV modules to date. This achievement represents another major advancement in core technologies, building upon the company's previous certification milestones in 2024 when Rollshine's flexible perovskite solar cells and modules (0.10cm² and 100cm² respectively) demonstrated certified efficiencies of 26.61% and 19.71%.
The research team at Rollshine Photoelectric Technology points out that achieving efficiency breakthroughs in flexible perovskite photovoltaic modules presents significantly greater challenges compared to conventional rigid perovskite photovoltaics, primarily due to performance limitations imposed by flexible substrates and encapsulation materials on high-quality, large-area perovskite thin films. These constraints include inferior optical properties (transmittance, refractive index, extinction coefficient) and poor surface morphology of flexible transparent electrode materials, significant thermal expansion coefficient mismatch between flexible transparent polymer substrates and perovskite films, greater difficulty in precisely controlling laser scribing parameters, and higher moisture/oxygen permeability of flexible encapsulation materials.
