It was the second time the tech was being displayed, following a brief showing that unfortunately coincided with the March 11 earthquake and tsunami in Japan.


The films stick onto windows, making them less susceptible to breaking in quake-prone Japan. They consist of five layered sheets and an organic photovoltaic substance.


They also help keep interiors cooler by absorbing more than 90 percent of infrared light, reducing the need for air conditioning in summer. At the 3M booth at Ceatec, there was a 13-degree C difference on one side of a window compared to the other, which was heated by powerful lamps but plastered with the sheets.


Compared to traditional 


"We've been a pioneer firm in window films, and we had already developed sunshade films and shatter-resistant films, so we added functionality to those," said Fumito Takada of 3M corporate communications.


A separate battery can store power generated by the films, which will hit the Japanese market next year. 3M is aiming at government structures, commercial buildings, and fast-food restaurants as potential customers.


They're expected to be one half to two-thirds the cost of traditional solar panels including installation.
