Since 2002, commercial production of solar cell manufacturers U. S. First Solar, finally in 2009 with the release of the largest manufacturers of solar cells. The secret lies in its process of high-suction vacuum cleaner, without more, lower manufacturing costs CdTe (cadmium telluride), solar cells. Its strength can be described as overwhelming, if the Japanese solar cell industry, said: “In the manufacturing cost has been unable to catch up with First Solar.”
Although CdTe solar cells have such a significant advantage, but perhaps because of the Cd (cadmium) toxicity distance, following the manufacturer’s production of First Solar few of these batteries. Has seven employees of Korean society risk Advanced Solar Dynamic (ASD) is one of them. A few days ago I interviewed ASD CEO Jay Lee Jae-Geun, he said with confidence “of the market based on CdTe solar cell to grow. The new space has also participated in the great enterprise.”
ASD CdTe solar cell is characterized by the formation of the CdTe layer is different from First Solar. First Solar uses a “close to the sublimation: First, the sublimation material, then deposited on the ground at 600 ℃ high temperature process. The DSA is the process used in the temperature around 350 ℃ spray. Lee said: “This method can further reduce manufacturing costs,” it calls into question the king occupies the throne of First Solar.
DSA in 2009 by 2-inch squares of test products to achieve a conversion efficiency of 12.6% (Voc than 775mV, JSC is 27.8A/cm2, FF 58.6%). In June 2010 began developing 20cm square module, also in December 2010 began to build can be made 60cm x 120cm wide 20MW module production line. Plan for the future through the layers in the structure of the series, to achieve a conversion efficiency of 25%.
To achieve these goals need across many obstacles, so do not know if ASD smooth as expected. However, I think that plans already in place to build a culture of solar energy manufacturing plant to feed the crocodile in Taiwan, or SDA, many dynamic companies in Asia.
