Patent ID: 8110427

Claim:
A manufacturing method of a stacked-layered thin film solar cell, comprising steps of: forming a transparent front electrode layer; forming a stacked-layered light-absorbing structure on the front electrode layer, which comprises steps of: forming a first light-absorbing layer, which has a p-type layer structure, on the front electrode layer by co-evaporation; forming a second light-absorbing layer, which has a p-type layer structure, on the first light-absorbing layer by co-evaporation; forming a third light-absorbing layer, which has a p-type layer structure, on the second light-absorbing layer by co-evaporation; forming a fourth light-absorbing layer, which has a p-i-n-type layer structure, on the third light-absorbing layer by co-evaporation; forming a fifth light-absorbing layer, which has an n-type layer structure, on the fourth light-absorbing layer by co-evaporation; and performing a reaction process on a surface of the fifth light-absorbing layer; and forming a back electrode layer, which is made of metal, on the fifth light-absorbing layer of the stacked-layered light-absorbing structure; wherein the stacked-layered light-absorbing structure consists essentially of I-III-VI compounds, in which group III elements comprise aluminum and indium.
