Sometimes, just a few cents can determine the success or failure of a technology. For example, as long as portable solar power generator prices are still more expensive than fossil fuels, the photovoltaic on the open market isn't competitive. If we want the future of renewable energy sources to penetrate the global market, we must make it cheaper.
And to achieve this goal is no panacea: impossible and boost efficiency, but also the production of high efficiency solar power portable generator and module costs. If you want to make a change, then you have to solve a puzzle, there are many variables: R & D teams around the world are in search of one of the latest technology and manufacturing methods to make cells and modules manufacturing cheaper, more efficient, more durable ,more reliable.
Silicone is a material one quite promising. This is a very unusual material - neither organic nor inorganic crystal polymer - and yet both have relevance. While portable solar power generator modules have begun to use silicone encapsulation, but until now has not been widely used in silicone laminated photovoltaic modules. At present, most manufacturers of photovoltaic lifePo4 batteries using EVA packaging materials.
Rafal Mickiewicz project manager said that when the silicone hardens, it encloses a photovoltaic cell; therefore electronic components have been optimized protection. Fraunhofer experts set up by silica gel laminated battery model, and these portable solar power generator modules at a low temperature and cyclic loading tests of artificial indoor climate. In addition, the researchers used electro-luminescent imager to detect microcracks situation. Compared with conventional PV module test results confirmed that surrounded silicone PV module more resistant to cyclic loading, and subjected to the test of strong winds, especially in the cold weather of minus 40 degrees Celsius.
"For two years, Dow Corning Corporation and Fraunhofer researchers team of PV modules to cooperate. This cooperation will greatly enhance its understanding of the requirements of PV module raw materials, in particular sustainability and generating capacity," Dow Corning solar power portable generator solve Andy Goodwin global science and technology program manager, said.
At the same time, this test was the 26th European Photovoltaic Solar Energy Summit published. Mickiewicz finally said: "This study demonstrates the silica layer is very suitable for application in some respects, because the fragile silicone shell protects the internal components, and can withstand large temperature fluctuations With this technology, we can make Si thin film storage battery ofe portable solar power generator. components made more robust.
