An international team of scientists developed a technique to isolate individual sources of electrical ‘noise’ within a solar cell. Comparing the technique to being able to pick out a single voice within a 200-person choir, they say the technique will help to improve understanding of where efficiency losses occur within a cell, and effective ways to mitigate them.
An international team has developed an integrated solar flow battery which has been suggested as ideal for off-grid locations. The device, which combines energy conversion and storage in one unit, can be used for lighting and recharging cell phones.
