Japan-based PXP Corporation (PXP) has announced the signing of a demonstration contract with JGC Holdings Corporation (JGC) and a local EPC firm to jointly develop an empirical demonstration project utilizing large-area flexible perovskite/copper indium gallium selenide (CIGS) tandem solar cells. The initiative aims to further validate the processability and durability of flexible solar technology.
Central to the project is JGC’s “sheet-based method,” developed for industrial facility rooftops. This approach integrates thin-film solar cells mounted on insulation panels into power-generating modules, securing them to rooftops using cylindrical metal fixtures called “clamps.” The innovative installation allows the thin-film solar cells to be detachable without compromising their lightweight, thin, and flexible properties.
PXP has successfully engineered high-efficiency, lightweight solar modules by stacking perovskite and CIGS solar cells. This tandem structure leverages the distinct wavelength absorption characteristics of both cell types, significantly enhancing photovoltaic conversion efficiency and offering an optimized solution for broader solar energy applications.
