TFT-LCD LCD panel manufacturers ranked second in the world - South Korean LG Display (LG Display Co., Ltd.) Was officially released will be put into thin-film solar cell industry. LG will be the second half of 2009 invested 50 billion won (about 4 billion yen), in Paju, Gyeonggi Province, South Korea build experimental solar cell production lines and outdoor power equipment, from 2012 onwards will be able to start commercial production of the battery.

Solar is currently widely used semiconductor material silicon crystalline silicon used, but with the existence of high prices of silicon feedstock shortage problem. Opposite, LG Display manufactured thin film solar cells, in the glass substrate or a plastic substrate, forming an amorphous silicon film, a significant reduction of the use of silicon material. Amplified by the substrate size, have the opportunity to make the manufacturing process to achieve efficiency and reduce energy consumption. In addition, the thickness of the film is relatively thin type battery, the application range more widely than the crystalline cell, for a feature.

LG Display to TFT-LCD manufacturing Know-how alive for solar cell business, 2009 will be in the second half of the LCD factory in Paju area construction and power generation facilities experimental production line. In addition to plans to transform both energy efficiency from the current 8%, increased to 12% in 2010, up 14% than 2012, and the manufacturing cost per watt down to one U.S. dollar or less, in 2012 began to prepare commercial production.

LG is the original solar power, building, public display for the production goal, but in the long term, mobile devices, car display is also a major focus direction. South Korea, LG Display's parent company LG Electronics previous step to strengthen the cause of solar power. The company expects to invest 220 billion until the end of 2010 won, in Gumi, North Gyeongsang Gyeongsan build two annual capacity of 120MW class crystalline solar sungoldpower cell production line.

In addition, LG's competitors, the world's largest LCD panel maker Samsung Electronics (Samsung Electronics Co., Ltd.) Also shows that will put solar cell business. According to Chosun Ilbo access the contents of Samsung Electronics Co. cadres, Samsung Electronics is currently invested 300 to 400 billion won, is the city of Yongin, Gyeonggi Xing plant construction unit annual capacity of 30MW solar cell production line, and consider investments in 2010 combined yards 3000 to 400 billion won, additional production lines in order to ensure the production capacity of 300MW.
