A method of producing a photovoltaic element (1) comprises forming a photovoltaic member (11) on a first area (A1) of a support member (12), such that the photovoltaic member leaves a second area (A2) of the support member free, and bending the support member (12) in the second area (A2) so as to enhanced the rigidity of the photovoltaic element (1). The support member (12) is substantially planar and is capable of being permanently deformed by bending, while bending the support member (12) may be carried out immediately after forming the photovoltaic member (11).
