While BIPV has been traditionally limited to providing a PV functionality on discrete elements of the building (windows, claddings, tiles, …) researchers have been more and more progressing on depositing Thin Film PV material on flat building material substrates other than glass, such as metal.

The present aimagesrticle relates to a highly innovative solution developed by researchers from the university of Kassel in Germany, consisting of providing concrete with PV generation capabilities.
While efficiencies are projected to remain well below the levels of current crystalline cells, the concept is of particular interest as it could – provided it is economically attractive – possibly apply to almost all non transparent building surfaces.

The pos­si­bil­i­ty of com­bin­ing DYSC cells with con­struc­tion ma­te­rials such as con­crete has been up to now over­looked. The main chal­lenge is now to op­ti­mize the cell’s long-term sta­bil­i­ty.

With projections of particularly low production costs, such a product, that is not yet in industrial phase, could potentially offer a new range of innovative BIPV applications.
