1. A method for manufacturing a photovoltaic cell, comprising:
- depositing a photo active layer onto a first substrate;
depositing a contact layer onto the photo active layer;
attaching a second substrate onto the contact layer;
removing the first substrate from the photo active layer, contact layer, and second substrate;
depositing a buffer layer onto the photoactive layer on a side opposite from the contact layer after removing the first substrate from the photo active layer; and
forming a semiconductor material in the buffer layer from the photo active layer and the buffer layer.
