CSEM Brasil and SUNEW Develop Fully Transparent Solar Film Using Cambrios' ClearOhm

MUNICH, GERMANY --- CSEM Brasil, SUNEW and Cambrios have jointly developed "OPV Power Film" that uses Cambrios' ClearOhm® materials to make transparent solar cells which will be integrated into windows and make use of the large areas available to produce power in buildings. OPV Power Film will be manufactured and sold by SUNEW, which was formed in 2015 to create the world's largest facility to manufacture OPV and revolutionize the solar industry in Brazil and worldwide.

The vision of net zero energy buildings (nZEB) requires that each building generates all the power it consumes. For this to be a reality it is not enough to use solar on just the rooftops of buildings but rather solar cells must also be integrated with the facades and windows of buildings. Traditional technologies such as silicon panels are heavy and cannot be easily integrated on the walls.

Organic photovoltaics (OPV) are the best option for building integration due to their intrinsic characteristics as they are highly flexible, lightweight, and available in many colors offering beautiful aesthetics. OPV is a good example of organic electronics ability to use large-area low-cost roll-to-roll printing which is very scalable to large volume production with low carbon footprint and low cost.

Commercial buildings are increasingly using glass facades and over 10 Billion m2 of flat glass was produced in 2016 with 70% going into facades. OPV Power Film is designed to easily integrate into the glass facades.
