可能としている。Moreover, as the solar cell 1, an amorphous solar cell is used, which is said to have a problem with heat resistance, but a metal diffusion prevention film 9 is provided between the amorphous silicon semiconductor layer 8 and the back electrode 10. Therefore, even if the temperature of the solar cell 1 increases, the metal component of the back electrode 10 can be prevented from diffusing into the amorphous silicon semiconductor layer 8, thereby preventing deterioration of the performance of the solar cell 1 due to heat. This makes it possible.
