Improvements made to the element capable of collecting light

The invention relates to an element capable of collecting light, comprising a first substrate having a glass function and forming a cover, and a second substrate forming a support, said substrates sandwiching between two electrode-forming conductive layers at least one functional layer based on an absorber material for converting light energy into electrical energy. The second substrate is provided on its lower face with a plurality of profiles (17, 18) oriented parallel to one of the sides of said element.
