How does it work? According to New Energy Technologies, through the use of the world’s smallest solar cells, which measure less than 1/4 the size of a grain of rice, but have been shown to produce electricity, according to a study by the American Institute of Physics.
The spray consists of organic materials that act as semiconductors that are both chemically and organically flexible, meaning that they can function to create electricity without impairing the transparency of the window. This article by Professor Xiaomei Jian of the University of Florida more thoroughly explains the process.
This process creates as much as 10 times the amount of energy as today’s commercial solar and thin-film technologies, according to a New Energy Technologies press release. These windows may also be able to generate electricity from artificial light sources as well as natural light.
New Energy Technologies is still developing these SolarWindows, so hard data on how much energy they can create or how cost effective they will be remains to be seen, but the potential is there to make solar energy far more accessible and affordable throughout the country.
