A solar cell module includes a substrate; an absorber layer formed over the substrate; a porous alumina passivation layer formed on an upper surface of the absorber layer; a buffer layer conformably formed over the passivation layer; and a transparent conducting oxide layer conformably formed over the buffer layer.

Passivation method

A method for reducing light-induced-degradation in manufacturing a solar cell, includes the steps of: (a) irradiating the solar cell with an irradiance; (b) maintaining the solar cell within a temperature range; (c) removing the solar cell away from the irradiance of step (a) after a time; and (d) determining the irradiance, the temperature range, and the time such that the LID is optimally below a predetermined LID.
