Energy Efficient, Transparent Solar Windows: You Really Ain’t Seen Nothing Yet

Posted by in categories: business, solar power, sustainability

Building integrated solar provides businesses with new bottom line opportunities to leverage their properties to attract a new generation of sustainability-focused consumers, and that leaves little space for fossil energy to maneuver.


More than 20 billion square feet of windows are installed every year, and the leading firm Andersen Corporation apparently plans to make some of those billions into energy efficient, transparent solar energy generators that could kick the pace of global energy decarbonization into high gear. The well-known maker of windows and doors just chipped in for a $30 million Series B funding round that will help push the not-so-well-known transparent solar innovator Ubiquitous Energy out of the startup shadows and into the bright sunshine of the global building industries marketplace.

Ubiquitous Energy Hearts Transparent Solar Windows

The idea of transforming windows into fully transparent, see-through PV powerhouses has allured researchers for years. Conventional solar panels block the sun, so that’s out. Thin film PV technology offers an alternative route, but the problem is squeezing out enough clean kilowatts to make the endeavor worthwhile. Thin film is transparent, but overall the technology is not as efficient as conventional photovoltaic panels.
