Ultra-thin transparent solar cells promise invisible charging for wearables, cars, and homes

NTU researchers developed ultrathin, color-neutral perovskite solar cells that can stay partly transparent while generating power.

The lab-scale devices were made using thermal evaporation and worked even under indirect light.

They reached up to 12% efficiency in opaque form and 7.6% in a semi-transparent version.

The team has filed a patent and is seeking industry partners to test scale-up and long-term durability.

If successful, the technology could add discreet electricity generation to windows, car glass, smart façades, and wearables.
