Flexible design of building integrated thin?film photovoltaics

The high cost of building integrated photovoltaics is one the main reasons preventing a more widespread application. We propose panel-on-demand concept for flexible design thin-film to address this issue. based on use semi-finished PV modules (standard mass products) with subsequent refinement into BIPV modules. In study, we demonstrate three processes necessary realize concept. First, prototype tool cut thin film photovoltaic elements glass substrates laser perforation was developed. Damage processed samples did not exceed distance 50 ?m from cuts. Second, oxide/metal/oxide-electrodes colour were applied Cu (In, Ga)Se2 cells and standard monolithic interconnection structuring used produce sized 30 × cm2 in red, green blue strong colours. Third, A back-end process developed amorphous silicon cells, which allows custom shape. strategy may allow streamlined production customized lower aesthetically pleasing, fully solar
