Solar cell module and light control sheet for solar cell module

摘要

A solar cell module is composed of a panel of transparent material that transmits sunlight, a panel of heat-conducting material arranged opposite to the sunlight incidence side, a light transmitting elastomer member, and a solar cell element, the light transmitting elastomer member and the solar cell element being interposed between the panel of transparent material and the panel of heat-conducting material, with the light transmitting elastomer member being disposed on the sunlight incidence side, in such a way that the light-transmitting elastomer member presses the solar cell element against the panel of heat-conducting material. By altering the optical path of the direct incident light with the refractive action of the light transmitting elastomer, the solar cell module allows the finger electrodes and/or bus bar electrodes of the solar cell element to be placed in the region where there is less incident sunlight than the region where there is direct incident sunlight not affected by refractive action. The solar cell module of the present invention has a high conversion efficiency and exhibits good durability during prolonged outdoor exposure. Therefore, it is useful for photovoltaic power plants of large scale which play an important role as the energy source to solve the global environment issue.
