This book is a must-read for those interested in the aging phenomenon of materials used in new energy systems, such as photovoltaic and electric vehicles. It provides a fundamental framework for this topic and important basic data and references for insulation materials used in these systems. It covers the aging of photovoltaic systems installed in different environments, including space, as well as the aging of the discharge present in the drive motors of electric vehicles. This book is suitable for researchers and students interested in green energy systems and can be used for teaching, research, and science popularization.

Jia-Wei Zhang was born in Ningxia, China in 1982. He received his master's degree in electrical engineering from Northeast China Institute of Electric Power Engineering in 2008. He received his Ph.D degree in 2012 from the Department of Electrical Engineering at the L'Institut National des Sciences Appliquées de Lyon (INSA De Lyon), France. He then worked as a Postdoctoral Fellow at the Department of Electrical, Electronic and Information Engineering "Guglielmo Marconi" of the University of Bologna (Alma Mater Studiorum - Università Di Bologna), Italy. In 2015 and 2016, he was an invited research fellow at Fukuoka University, Japan. In 2018 and 2019, he was an invited professor at Heidelberg University and Heidelberg Institute for Theoretical Studies (HITS), Germany. He was awarded by the international exchange program of Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan and Deutsche Forschungsgemeinschaft (DFG) of Germany. At present, he works as a professor at Xi'an University of Technology. He also work as Director of Overseas Expertise Introduction Center of SX, Director of Institute of High Voltage and Innsulation XAUT and Co-director of Joint Laboratory of Morocco-China Green Energy and Advanced Materials (LGEMA). His research interests include electrical aging and insulation failure risk of electrical equipment in Renewable Energy System and the sensor for the Smart Grid based on functional dielectrics after polarization.
