Dr. Taguchi is a General Manager of the Eco Solutions Company of Panasonic Corporation, Japan. He joined Sanyo Electric Co. (now owned by Panasonic) in 1988 after graduating from Department of Electrical Engineering, Kyoto University and received a Doctor of Engineering from Nara Institute of Technology in 2007.
He engaged in the R&D of the silicon heterojunction solar cell from the beginning and developed the breakthrough structure that is now used in the Panasonic’s PV module HIT®. He has led the R&D group and continuously renewed own record efficiency for years, and accomplished 25.6 % with back-contact type silicon heterojunction cell in 2014.
Some of his award in the past couple of years are:
The silicon heterojunction [SHJ] structure adopted in Panasonic’s photovoltaic module HIT® is recognized as one of the highest efficiency solar cells that has following advantages over a conventional c-Si solar cell, (1) a high efficiency over 22% with high open circuit voltage [Voc] of more than 720 mV, (2) higher power generation in practical use due to the world's leading output temperature coefficient of -0.258%/°C, (3) a symmetrical cell structure essentially suitable for bifacial module.
