  • Amorphous semiconductor solar cell
    Patent number: 5104455
    Abstract: An amorphous semiconductor solar cell includes an i type layer which is an at least partially alloyed, substantially intrinsic semiconductor, an n type layer formed on one side of the i type layer, and a p type layer formed n the other side of the i type layer, and the i type layer has its energy bandgap varied in a thickness direction to have a bandgap larger than the bandgap of the p type layer in the vicinity of the interface with the p type layer.
