Niedersächsisches Ministerium für Wissenschaft und Kultur Leibnizufer 9 30169 Hannover Germany Press information HANNOVER MESSE 2016 Guiding the Sun The Institute for Solar Energy Research (ISFH) uses light-guiding structures to increase the efficiency of large-area solar modules made from industrial solar cells to a record value of 20.2%. Highly reflective and structured materials are utilized, which guide more light onto the active solar cell surfaces and increase the area efficiency of the module, lowering the costs of photovoltaic (PV) systems. Light-management is essential for PV systems and a main research topic at ISFH. Bifacial cells facilitate light harvesting from both sides as well as innovative interconnection schemes. Macropores and rear-side contacts are used to lower the front side reflection. The software DAIDALOS can be used to trace the path of light rays through a PV system. -1- 08.04.2016 13:29
