Because perovskite solar cells work better than silicon in low light, Poland-based Saule Technologies says semi-transparent cells could be clad on buildings in built up areas, as in this rendering.

As the technology develops, perovskite could be printed onto flexible rolls, and wrapped around buildings.

Saule predicts that perovskite solar cells could eventually be integrated into street furniture, where they could power street lights and charge electronic devices.

Saule Technologies uses an inkjet printer to make its perovskite solar cells.

Their light weight means they have the potential to be installed on rooftops more easily than silicon panels.

California-based Swift Solar is working on incorporating its perovskite material into asphalt shingles, as in this rendering, which are used for roofing.

It says perovskite technology could eventually be incorporated into cars and planes.
