Abstract

A solar cell module comprises a front surface member disposed on a front surface side of a photovoltaic element having at least a semiconductor photoactive layer on a flexible substrate, a back surface member disposed on a back surface side of the photovoltaic element, and a sealing material interposed therebetween. The flexible substrate of the photovoltaic element has a plurality of substantially parallel surface grooves on a surface thereof at the semiconductor photoactive layer side of the flexible substrate. At least one portion of the solar cell module is processed to deform in such a direction that strain generated in a substantially parallel direction to the surface grooves is applied to the photovoltaic element. In this way, a solar cell module can be subjected to deformation-processing that prevents, to the extent possible, cracks in the semiconductor photoactive layer of the photovoltaic elements; in other words, deformation-processing can be achieved without influencing electrical characteristics. A method of producing such a solar cell module is also disclosed.
