With the continuous advancement of technology, thin film photovoltaic solar cell conversion efficiency was rapidly rising, now more than 2 years ago raised about -40% 30%, although in comparison with crystalline silicon cells have very different, but the materials used small, simple, low energy consumption and the cost advantage is increasingly being accepted by the industry. So almost 3 years, thin-film solar cell industry developed rapidly.
As traditional manufacturing power and solar energy, the Japanese in the development of thin film solar cells are also spared no effort. In 2008 as a result of global demand for silicon raw material prices lead to boom, the Japanese solar cell manufacturers have transferred to low-cost thin film materials sectors. For consultants in the research department of the latest energy industry that in 2008 Japanese film solar cell production capacity of 440.5MW, an increase of 133.7%.
Another good news is that June 24 the United States the world's leading thin-film solar FirstSoalr legal description in Las Vegas said the plan to 2014 thin-film CdTe solar cell module manufacturing costs per watt will reach 0.52 ~ 0.63 U.S. dollars, which per watt than the current cost of about 0.93 U.S. dollars fell 30 ~ 40% conversion efficiency rose to 10.9 percent from the current 12.5 percent, 1.6 percentage points to upgrade.
