| Popis: | 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 3850-3853 Imec has developed a new technology concept to integrate and interconnect back-contact solar cells into modules, based on embedding cells in silicone on top of a glass substrate. This so-called i-module (interconnect module) technology aims at an improved optical performance and reliability, combined with an increased throughput for module manufacturing, through the use of silicones and a module-level interconnection that eliminates string handling. One of the additional advantages is that the technology could therefore be suitable for integrating very thin cells into modules. The paper will first elaborate on the process flow, its background and motivation. A lot of options are still open for consideration, but technical feasibility is demonstrated for two distinct implementations. Materials and processing are discussed for these cases, as well as the resulting module measurements. Then the methodology behind the followed reliability approach is discussed on a general level and some first results on accelerated reliability testing and outdoor weathering are shown. Finally, a view on future developments is given as an outlook. |
