Sanyo developed a thickness of only 0.1 mm thin film solar cell efficiency

According to Japan's Kyodo News agency reported that Japan's Sanyo Electric Co. announced the 18 developed only half of its original thickness, about 0.1 mm of solar cells. The battery-piece basic components of solar cells, solar energy conversion rate reached the highest level of 22.8%. Sanyo hopes to mass production a few years later, when the solar power system is expected to push prices down.

Solar panels from a combination of solar cells. The existing ordinary cell thickness of about 0.2 mm, and the cell thickness of only 0.098 mm. Usually the battery thickness thinning will reduce the amount of light absorption, resulting in current and voltage goes low, the output power decrease. However, according to Sanyo's introduction, by improving the bonding technology to improve the absorption effect by preventing the decline in power output.

Thin film batteries will allow the use of silicon raw materials, reduced by about 25% lower costs help drive down the price of solar panels. In addition, the battery can also be adjusted to expand the use of film curvature. Sanyo announced in May of this year developed the world's first solar energy conversion rate (23%) of solar cells.
