Agenda

10:35–11:20	Recent Progress in Crystalline Silicon Solar Cells Yoshio Ohshita Associate Professor, Semiconductor Lab. Toyota Technological Institute The indestory of crystalline silicon solar cell has underdone rapid growth recently. This growth was fostered by many breakthroughs based on the science and techonolgies. However, to realize the 2030PV+ roadmap in Japan, the new technologies for realizing the higher efficiency and lower cost silicon solare cells are requred. I will disucss the issues of the recent advanced technologies and the future direction of feed stock, crystal growth, slicing and cells.
11:20–12:05	Recent Progress of High-efficiency Technology for HIT Solar Cells Eiji Maruyama General Manager, Advanced Energy Research Center SANYO Electric Co., Ltd. Sanyo has successfully commercialized HIT photovoltaic modules for power generating systems. HIT photovoltaic modules are well known as one of the high-performance modules all over the world.　In my presentation, I’m going to introduce our recent activities for increasing the competitiveness of HIT photovoltaic modules. For this purpose, it is very important to thoroughly reduce the power-generating cost. I’ll show you our 4 main approaches and their recent progress.
12:05–12:50	Current status of the fixed abrasives tools in photovoltaic manufacturing technology Yoichi Kondo Assistant Manager, Development & Engineer Group, Strategic Development Projects Center, Cutting Development Unit, NORITAKE CO., LIMITED Slurry wire has been employed for wafering process of solar silicon ingot for years. However, its low process efficiency and poor working environment have been an issue. The fixed diamond wire has long been desired for better process efficiency and working environment. In comparison with slurry process, its environmental and process efficiency could be better; more than 2 times faster process efficiency, 1/50 of environmental loss. In this lecture, I will report about the current status of the fixed diamond wire as well as the fixed-abrasive-lapping & polishing tools used in the other processes.
