Cambridge scientists have developed algae solar cells that could be used to store energy in remote rural communities . Biological solar cells are single - cell green – algae – to harvest solar energy through photosynthesis . “In particular, because algae grow and divide naturally, systems based on them may require less energy investment and can be produced in a decentralised fashion.” In a paper in Nature Energy , researchers outlined how they successfully developed a system that separates charging and power delivery . This means cells are more efficient , with less internal resistance and lower electrical costs , said Professor Tuomas Knowles from the university 's department of chemistry . This could prove useful in rural Africa and south Asia , as electricity could be made locally without the need for high - tech factories .
