Electronics giant Sanyo recently announced the development of what they are claiming is the world’s most efficient solar module. Called the HIT-N230, the new module has an impressive energy conversion efficiency of 20.7% which is unprecedented in the market.

How did Sanyo achieve this feat? According to Akihabara News’ report, the leader in solar module manufacturing increased the number of solar cell tabs from 2 to 3 and made each tab thinner. They also applied AG coated glass, which allows “light trapping” or reduction of reflection and scattering of light.

While the N230 is getting the most attention for its high efficiency, Sanyo has another model in the N series – the N225 (225W) – and both are scheduled to be launched in Japan in Autumn 2010.
