ITO Electronics show prototype solar windows based on organic photovoltaic (OPV)

The window is made by placing 96 organic thin-film solar cells (polymer type, 5 x 5cm each) between transparent acrylic plates

It has been reported by Tech-on that Ito Electronic recently exhibited a window equipped with organic solar cells at the 1st Intl Building & Urban Development Expo, which took place at the end 2016, at Tokyo Big Sight.

According to the report the "Smart Power Generation Window" is currently under development - and is capable of generating 3Wh of electricity per window (44.9 cm x 101.5 cm) per day on average.

The window is made by placing 96 organic thin-film solar cells (polymer type, 5 x 5cm each) between transparent acrylic plates.

Specifically, 32 of them have a sunlight transmittance of 0% while the remaining 64 have a sunlight transmittance of 30.4% The conversion efficiencies of the former and the latter are 3.50% and 2.00%, respectively. The rated output per window is 1.2W.

[Editors note: Although the article does not mention who mande the OPV devices Yamagata University can be seen on the label - suggesting that they were most likely involved in the fabrication of the prototype devices]
