Integration of photovoltaic systems into existing buildings - PV modules with modified appearance
The market for refurbishing and modernisation of existing buildings is much larger than the market for new buildings. This means that the opening of this market for BIPV is not only an aesthetical problem but also an important economic issue. However, it is often a challenge to achieve aesthetically satisfying building integration of photovoltaic modules. The work reported here pays special attention to architectural and aesthetic topics in the use of thin film PV technologies for BIPV. CIS modules with modified optical appearance could provide new opportunities to the creative work of architects. The module appearance can be influenced in several ways. One of them is to colour the module, another one is to modify the structure of the surface in order to change its reflection properties. The colouring of modules can be achieved either by using tinted cover glasses on the top of the cell in combination with a decoupling layer or by using specially coated glasses which can be laminated directly onto the cell. Following these approaches, a large number of coloured glasses were measured and evaluated and a big variety of patterned glasses were examined, respectively. The most promising combinations were produced first as small samples and later on in the final size and integrated in a transom mullion test facade at the ZSW test site in Widderstall, Germany, and a structural sealant facade at the premises of Permasteelisa in Vittorio Veneto, Italy.
