Many small-scale products available on the market were designed for outdoor use or outdoor charging. Among these are emergency kits for hikers, and phone chargers, torches and lamps such as the Little Sun products or the SOLVINDEN table lamp by IKEA [36, 37]. Generally, the module size of these products is a few square centimeters and the material is crystalline or amorphous Si. Although some products use high efficiency cells, they are not optimized for the spectral indoor conditions in their distribution and intensity. Other outdoor-related applications include solar fans for camping or solar power LED lamps. The module sizes for these applications already come close to the range of square meters.
