Abstract
A method includes depositing an acid over a portion of a buffer layer of a solar cell substrate. A front contact material is deposited over the buffer layer, such that the front contact material does not bond to the portion of the buffer layer having the acid on it. Thus, the front contacts of adjacent solar cells of the solar cell substrate are formed with a separation between them.
