Scientists in the Netherlands have demonstrated an interdigitated back contact copper-indium-gallium-selenide solar cell with a sub-micron thickness of 673nm. The device has an aluminum oxide and magnesium fluoride-based anti-reflective coating.
Korean scientists have unveiled a colorless device made of silicon microwire composites. The enhanced light absorption of the cell, the researchers claim, is due to the re-absorption of light by the microwires, which also benefit from an enhanced electric field.
Scientists at Switzerland’s University of Applied Sciences Rapperswil have demonstrated an aluminum conversion process which could be valuable for long-term renewable energy storage. Simulations suggest that by employing the process, a new multi-family building in Switzerland could meet all its energy demand from a 7-11 kWp solar system.
Technology made in China competes with conventional plasma-based equipment to deposit the aluminum oxide layers at the heart of passivated emitter and rear contact (PERC) cells.
