USE OF GLASS FOR APPLICATION TO PHOTOVOLTAIC POWER GENERATION

摘要

PROBLEM TO BE SOLVED: To provide glass specifically suitable for application to photovoltaic power generation, and bringing improved results for the photovoltaic power generation.;SOLUTION: The present invention relates to usage of glass for application to photovoltaic power generation, where the glass has moisture content smaller than 25 mmol/liter and, specifically, greater than 1 mmol/liter. Preferably, the glass used indicates a transformation point T_g in a range higher than 580°C, an operation temperature (VA) in a range lower than 1150°C, and a heat expansion coefficient in a range of approximately 7-11×10^-6/K. Such glass does not release any semiconductor poison such as iron, arsenic and boron, can be used for high temperature processing, and especially, is suitable for application to Cd-Te-photovoltaic power generation, application to CIS-photovoltaic power generation, or application to CIGS-photovoltaic power generation. This is because, based on workability/higher heat stability at higher temperature, deposition different from that for soda lime glass conventionally used can be performed and has great advantage.;COPYRIGHT: (C)2012,JPO&INPIT
