Super-efficient solar cells

Electronics company SANYO has finally launched  its most powerful solar cells to date – claiming a 21.1% efficiency with a module output of 235W. Shipping of this new module will commence across Europe from this month.

The much-hyped cells were announced months ago but are only now available to consumers, enhancing performance and value in limited space installations.
But be warned, the modules themselves only claim efficiency of of 18.6% – and it is the modules you will be buying, not the cells on their own.The high efficiency cells also benefit from a new tab design so “ the effective area is enlarged to capture more sunlight and realize an improvement in efficiency.”
The new modules also feature anti-reflection coated glass. This effect is especially noticeable in the morning and evening, when the sun is low.
