Engineers at UNSW Sydney have developed a way to monitor solar cells at a microscopic level while they are operating to discover exactly how damage caused by ultraviolet light can be naturally repaired. The new monitoring method allows experts to directly observe chemical changes inside high-efficiency silicon solar cells as they degrade under UV exposure, which in turn is expected to help develop processes that can help the cells recover using normal sunlight.
