Because of their physical nature, the theoretical efficiency border is at 29.3 percent. According to the researchers this maximal theoretical border can be increased up to 40 percent – with the help of built-in organic layers in the solar cells.
This increase of energy gain would be a significant milestone for photovoltaics (pv) because they would be able to produce massively more electricity.
In combination with an energy storage, a pv-system will probably produce power cheaper than average off the power grid. Local, central producers will lose ground because of this, while the decentralized energy production increases.
