A new efficiency record for organic photovoltaic cells has been reached by Heliatek, for the third time in a row. The German company created a cheap solar cell that can convert up to 9.8 percent of the incoming light into electricity.
Heliatek’s new solar cell is made from oligomers, and differs from polymer and dye-sensitized solar cells because the cells can be produced at low temperatures and uses the least amount of non-toxic materials.
