ResearchSubjectsTo attain higher conversion efficiency of crystalline silicon solar cells (cells and modules) and lower production costs, research is in progress on new structures and fabrication pro-cesses for solar cells.●Establishment of high-accuracy silicon ingot slicing technology●Improvement of efficiency and cost reduction of crystalline silicon solar cells●Fabrication techniques for next-generation highly efficient solar cells 　(smart stacking technology)●Improvement of efficiency and reliability of crystalline silicon PV modulesPhotovoltaic Power TeamSolar cell test production facilitySmart stacked solar cellHighly Efficient Solar Cells at Low Cost by “Capturing More Sunlight”r cellsThin crystalline silicon Bifacial solar cell, half the thickness of conventional cells (0.1 mm)Higher efficiency and lower production costs of crystalline silicon solar cells are essential for the continuous deployment of photovoltaic power systems in the future. The PV power team is conducting advanced research and, in collaboration with industries, using a compre-hensive facility equipped with test production lines from crystalline silicon ingot slicing to solar cell/module fabrication.The team is devel-oping crystalline silicon based ‘smart stacking’ technolo-gy that laminates solar cells made of different materials to achieve next-generation solar cells with con-version efficiency higher than 30%.Demonstration Field5
