Abstract
A photovoltaic cell manufacturing method includes depositing a first buffer layer for performing lattice relaxation on a first silicon substrate; depositing a first photoelectric conversion cell on the first buffer layer, the first photoelectric conversion cell being formed with a compound semiconductor including a pn junction, and the first photoelectric conversion cell having a lattice constant that is higher than that of silicon; connecting a support substrate to the first photoelectric conversion cell to form a first layered body; and removing the first buffer layer and the first silicon substrate from the first layered body.
