High-efficiency, foldable silicon solar modules combined with the curtain fabrics

AFFORDABLE AND CLEAN ENERGY     2019/11/15
In response to global warming and extreme climate change crisis, wide-spread use of green energy has become an urgent task. Since the products on the market are dominated by single polycrystalline silicon solar cells, the power generation efficiency is around 20-25%. Also, the power generation cost per watt is less than 1 US dollar. However, current outdoor solar power generation requires high-reliability module packaging, which increases electricity costs. The growth of rooftop and outdoor solar panel installation can also be limited by government regulations, land area, and building space constraints. In order to popularize the application of solar products, and make the light-weight modules easier to carry; therefore, this work proposes a variety of lightweight packaging materials to make high-efficiency, foldable silicon solar modules combined with the curtain fabrics to achieve household solar power generation. Since the indoor environment is stable compared to the outdoor environment, and particularly the ultraviolet light resulting in poor power conversion efficiency is almost absorbed by the glass of the window, we can use a variety of Silicone, PET, and TPU films for light-weight solar module packaging, and can mitigate material degradation due to ultraviolet irradiation. In addition, indoor sunlight often irradiates obliquely. Thus the solar curtain should possess superior anti-reflective properties for large angles of incidence to achieve high-efficiency power generation. Therefore, the front-transparent module encapsulating material can also employ silicone with surface nanostructures. With specific adhesives, we can now combine different curtain fabrics with the lightweight silicon solar modules to achieve an elegant and beautiful appearance. Since the design of this work can reflect the characteristics of the lightweight, flexibility, bendability, foldability, and adhesion to the curved surface, the power generation efficiency is similar to that of mainstream silicon solar cells, so it can be implemented in this work as well. What''''s more, it can be expanded to outdoor camping, marching, installation art, public facilities, etc., making the light-weight solar cell module easy to carry and popularizing various applications.
