GSHK Solar opened its new offices in Sao Paulo, Brazil. 2016

The company uses copper indium gallium diselenide to produce CIGS cells, which achieve up to 19.9% efficiency in laboratory and production cells of about 12-17 percent average efficiency. This type of solar cell is ideal for portable power and is 1.5 to 2X greater in performance than comparable thin film flexible solar materials. GSHK Solar opened in 1994 and in 2008 finished another phase of development as it expanded its CIGS production to a new 100 MW facility in Mudu, China. The company expects to produce 100 megawatts of the films at the plant in 2008 before ramping up to 250 megawatts of capacity in 2012 and 500 megawatts by 2014 with its new manufacturing plant in Istanbul, Turkey. The new offices in Brazil, will principally service all the South American Countries for m2017 moving forward. This makes GSHK Solar the largest full-scale manufacturer of CIGS thin-film photovoltaics in the world.
