| Abstract |
We propose an indoor blind-type solar module that can be applied to the windows of buildings. A comparative study was conducted with solar modules by alternatively assuming crystalline silicon, CIGS, or amorphous silicon thin film solar cell technology. It is self-evident that the output power of the crystalline silicon solar cell module is the largest, but the power gap between modules is smaller than that predicted from the cell efficiency because the module power loss in thin film solar cell modules is comparatively small. In addition, since the temperature coefficient of the thin film solar cell is smaller than that of the crystalline silicon solar cell, the output power gap between the crystalline silicon and thin film solar cell modules is further reduced when operating in a high temperature environment. It is expected that this blind-type solar module would contribute about 10% reduction of the existing fossil energy generation, and about 50% of electricity consumption per household as an urban auxiliary power source. |
