POLYMER-BASED SOLAR CELL

摘要

Described are processes for enlarging the surface area of a polymer-based solar cell relative to a flat surface and/or for enlarging the active surface area of the organic semiconductor layer of the solar cell in relation to a flat surface. There is further described a polymer-based solar cell (1) in which the active surface of the organic semiconductor layer (13) has a surface profile which enlarges the surface area in relation to a flat surface profile. The surface has raised portions and/or depressions.
