SOLAR GRADE SILICONThe production of solar cells from silicon presents major challenges in terms of the purity of the silicon. The most common method for purifying the raw silicon is the Siemens Process, which was originally developed for microelectronics. Companies and research groups worldwide are working on less laborious, and therefore more cost-effective, production methods that are specifically tailored to the requirements of solar technology. One promising possibility is the production of solar grade silicon from metallurgical grade silicon. Solarvalue AG has the objective to produce inexpensive solar grade silicon out of metallurgical grade silicon for the photovoltaic industry by a step by step purification. ![]() ![]() ![]() ![]() ![]() ![]() ![]() 01_02_03_04_05_![]() ![]() ![]() ![]() 02_SOLAR SILICON |
