Ibm Unveils Breakthrough In Solar Farm Technology

摘要

IBM announced a breakthrough in photovoltaics technology that could reduce the cost of harnessing the Sun's power for electricity. By mimicking the antics of a child using a magnifying glass, IBM scientists are using a large lens to concentrate the Sun's power, capturing a record 230 watts onto a centimetre square solar cell, in a technology known as concentrator photovoltaics, or CPV. That energy is then converted into 70 watts of usable electrical power, about five times the electrical power density generated by typical cells using CPV technology in solar farms.rnIf it can overcome additional challenges to move this project from the lab to the fab, IBM believes it can significantly reduce the cost of a typical CPV based system. By using a much lower number of photovoltaic cells in a solar farm and concentrating more light, IBM's system enables a cost advantage in terms of number of components.
