80% Improvement In Solar Cell Efficiency
An anonymous reader writes "Chemistry researchers at Oak Ridge National Laboratory say they've improved the efficiency of typical solar cells by a whopping 80% by creating a 3-D nanocone-based solar cell platform. The technology tackles the problem of poor transport of charges generated by solar photons. These charges — 'negative electrons and positive holes' — typically become trapped by defects in bulk materials and degrade performance. 'We designed the three-dimensional structure to provide an intrinsic electric field distribution that promotes efficient charge transport and high efficiency in converting energy from sunlight into electricity.' Bottom line, they say, is they've boosted the light-to-power conversion efficiency of photovoltaics by 80 percent."
Actually, it does matter, because if you start from a less efficient process and go up, you may not exceed the efficiency of a more efficient process. So the amount you can 'get from a solar panel' may not change at all.
Which is, if you read the article, actually the case here.
