Australian Scientists Break Si Cell Efficiency Record

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.’
