Scientists at the Australian Research Council Photovoltaic Center of Excellence, at the University of New South Wales, report that they have become the first to reach 25% efficiency in a silicon solar cell, according to a United Press International article.
The center also holds the previous efficiency record of 24.7% efficiency.
‘Since the weights of the colors in sunlight change during the day, solar cells are measured under a standard color spectrum defined under typical operational meteorological conditions,’ notes Martin Green, one of the scientists.
‘Improvements in understanding atmospheric effects upon the color content of sunlight led to a revision of the standard spectrum in April,’ he says. ‘The new spectrum has a higher energy content both down the blue end of the spectrum and at the opposite red end.’
