Transparent solar cells - solar windows

Local and distributed energy production from non-fossil sources is necessary for a future resilient society. By using transparent solar cells more surfaces of buildings could be used for energy production, both from esthetic and practical reasons. Problems with alternative transparent solar cell technologies and why they are not commercial available are limitations like they have limited transparency and color distortion, contain toxic and rare materials, or have very low efficiency.

By using nanowires made of semiconductor materials and apply them in a transparent film we have overcome those problems and have a technology that can be scaled up to mass production of solar cell windows.
