![]() ![]() The issue of heating can be even more critical in bifacial modules: high fractions of rear irradiance can lead to higher operating temperatures. ![]() Furthermore, many of these approaches are complex and expensive to fabricate. However, there are many competing strategies to reject this light: selective reflectors could be integrated into the outer module glass, at the textured more » Si-encapsulant interface, or on the rear. Since much of the elevated temperature of the modules derives from parasitic absorption of sub-bandgap sunlight by the contacts, encapsulants, or other materials, reflectors that remove the sub-bandgap radiation from the module before it is absorbed promise to reduce the operating temperature. These elevated operating temperatures lead to diminished performance, reducing efficiency by ~0.4%/K for crystalline Si cells and decreasing module lifetime. When installed outdoors, Si solar cells typically operate 20 – 30 K above ambient conditions.
