These flexible cells achieve 9.2 percent energy efficiency while maintaining 35 percent transparency.

Researchers at the Hebrew University of Jerusalem have created semi-transparent, color-tunable solar cells.

Interestingly, these can be 3D-printed onto windows, building façades, and flexible surfaces.

These panels shed the bulky, industrial look of solar arrays, giving designers the choice between a slightly transparent window or a vibrant, color-tinted architectural feature.
