Turning Building Windows from Passive Isolating Material to Active Power Generator Material

Semi-transparent solar cells that can be incorporated into window glass of buildings are a “game-changer” that could transform the architecture paradigms, urban planning, and power generation grids. A team of researchers from the ARC Centre of Excellence in Exciton Science and Monash University have come up with semi-transparent solar cells that have 17% power conversion efficiency (PCE). Exciton Science and Monash University are located in Australia.

This technology will transform windows from passive isolating materials into active power generators, potentially revolutionizing building design. Two square meters of the solar window with semi-transparent solar cells will generate about as much electricity as a standard rooftop solar panel, according to the researchers’ say.

It is worth mentioning that a rooftop solar installation has on average a PCE of between 15 and 20%. It could become one of the major mainstreams of the building industry, especially Building- Integrated Photovoltaics (BIPV), in the near future.
