Germany needs a multiple of installed photovoltaic capacity to make its building stock climate-neutral by 2050. Building-integrated PV (BIPV) has a key role to play here. Building-integrated photovoltaics enable facades to be used in an energy-efficient manner. A great advantage is when already existing surfaces or surfaces that are to be built anyway can be used several times. Why is BIPV still so little common despite many advantages? What are the reservations and how can they be overcome?
Dr. Björn Rau, head of the consulting office for building-integrated photovoltaics at the Helmholtz Zentrum in Berlin, reveals.

At the Competence Center Photovoltaics Berlin (PVcomB), part of the Helmholtz Center in Berlin, thin-film photovoltaic technologies and products are developed together with industry. Technology and knowledge transfer takes place in research projects with industrial partners and through the training of highly qualified specialists.
Dr. Björn Rau heads the Advisory Office for Building Integrated Photovoltaics (BAIP) at PVcomB, where he is deputy institute director & head of technology.
