Energy storage systems are one of the key technologies for the energy turnaround. With their help, the fluctuating supply of electricity based on photovoltaics and wind power can be stored until the time of consumption. A number of pilot plants of solar cells, small wind power plants, lithium-ion batteries, and power electronics are now under construction to demonstrate how load peaks in the grid can be balanced and what regenerative power supply by an isolated network may look like in the future.

Photosynthesis allows plants to convert light into chemical energy. Utilizing this process to produce electrical energy is a research goal worldwide. Scientists have now demonstrated that a photosynthetic protein system can be integrated into artificial photovoltaic device architectures while retaining biomolecular functional properties. The proteins represent light-driven, highly efficient single-molecule electron pumps that can act as current generators in nanoscale electric circuits.

A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells perform well in different light conditions including partial shade making them well matched to consumer electronic devices such as e-book readers, cameras and some mobile phones.
