Abstract
According to an aspect of the present invention, there is provided a method for manufacturing a compound semiconductor solar cell, comprising: forming a sacrificial layer on one surface of a mother substrate; forming a compound semiconductor layer on the sacrificial layer; forming a first protective layer formed of a compound semiconductor on the compound semiconductor layer; depositing a second passivation layer on the first passivation layer; attaching a first lamination film on the second protective layer; separating the compound semiconductor layer, the first and second protective layers, and the first lamination film from the mother substrate by performing an ELO process to remove the sacrificial layer; forming a back electrode on the compound semiconductor layer; attaching a second lamination film on the back electrode; removing the first lamination film; removing the second protective layer; removing the first protective layer; and forming a front electrode on the compound semiconductor layer.
