Enhancement Electricity Producion in Same Ground Area by Curved Tessellated Bifacial Si Solar Cells

Abstract

The strategies for PV have been watt-per-cost concepts and it changes to consider energy-yield-per-watt for more energy per installed PV according to expanded PV applications. Bifacial solar cells have received attention from these demands. In this study, as new concept for bifacial technology in urban environment needs, we have proposed automated sun trackable and shape transformable 2-D tessellated bifacial module at the sun position that can be applied to at any curved surface, and change their shapes according to AOI to receive more solar energy and maximize power output without external helps. With this introduced self-shape-transformable 2-D tessellated bifacial module with intervals and reflector, 47% enhanced power output obtained compared to flat module. At high AOI, power output is higher than flat module so it is significant meaningful in application in urban environment.
