Until now, the module’s base has been a compound triple-junction solar cell that stacks three light absorption layers with indium/gallium/arsenide as the bottom layer, but we changed to a new structure with a double-step junction of indium/gallium/phosphorous and gallium arsenide as the top layer and silicon on the bottom layer.
The prototype solar cell module has achieved high efficiency by efficiently converting light of various wavelengths into energy by a new structure which has compound two-junction solar cells on the top layer and silicon solar cells on the bottom layer.
Sharp Corporation, working under the Research and Development Project for Mobile Solar Cells *3 sponsored by NEDO *4, has achieved the world's highest conversion efficiency of 33.66% in a stacked solar cell module that combines a tandem double-junction solar cell module *5 and a silicon solar cell module.
Based on this background, Sharp is developing technology for solar cell modules that can be mounted on mobile equipment that feature high efficiency and low cost and which will be widely installed on regular electric vehicles and mobile units as well as for use in the space and aviation fields.
However, increasing power conversion efficiency (PCE) beyond the S-Q limit will lead to technological challenges and dramatically escalating costs in single-junction-based PV cells. The perovskite solar cells (PSCs) paved the way towards cost-effective and high-performance PV technology.
Low-cost, stable, and easily processed semitransparent carbon electrode-based perovskite solar cells (c-PSCs) without hole transport material (HTM) and highly efficient crystalline silicon (c-Si) PV cells were utilized as top and bottom cells, respectively.
