Editor's note: copper indium gallium selenide (CIGS) thin film photovoltaic cells is different with the current mainstream silicon based solar photovoltaic cells, the advantages of the latter is photoelectric conversion rate is high, the polysilicon can reach 18%, silicon can reach 20%, the disadvantage is high cost, weak light of poor, can not be bent, a recession etc.. With the progress of copper indium gallium selenide thin-film batteries of glass and optical materials, its photoelectric conversion rate can be improved even close to the level of silicon solar cells, and the production of low cost, little pollution, recession, weak light performance is good, and other notable features is its by more and more users of the popular reason.
By 2020, solar PV will occupy the global annual new generating capacity by half.
According to GTM's latest report on the global PV market demand outlook, 2015 global PV new installed capacity will reach 55GW, compared with the last year, an increase of 36%, the growth rate is much greater than 2% in 2014.

2015 would be a year of excellence if it was the "transition year" in which it was reported in 2014. This year, due to China's pull, Asia Pacific new PV installed capacity will account for more than half of the world. Europe will open up a rising trend; North America, mainly the United States will continue to grow year after year.
"China has become the world's largest photovoltaic market, subsidies for the new Internet price as well as the" Five Year Plan "ambitious solar target, consolidated the position," GTM Institute for solar energy analyst, the report's author, Adam James wrote. GTM Asia Pacific region in 2015 is expected to increase the 30GW PV capacity, China will account for 14GW.
Europe's share of the global market has continued to decline since the 2004-2011, which has been in a leading position in the world. However, GTM research is expected to reach a minimum of 21% of its shares this year, and in 2016 again. By 2020, Europe's new PV installed capacity will reach 42GW, accounting for 31% of the global market.

U.S. PV market will be the third largest market this year, only after China and japan. GTM Institute forecast that the United States this year will add 8GW, accounting for 14% of the global market.
Today, the prosperity of the global PV market is largely dependent on the promotion of policy. However, as the cost continues to decline, we are gradually entering an era of economic success, solar PV market is increasingly becoming the market competition oriented. The report also pointed out that there will be new countries continue to join.
"The most significant change in the global PV landscape is the addition of regional emerging markets, such as Latin America, Africa, and the Middle East. They will be from a lower 1% share, up to about 5 after 17% years." James said.
"Our core argument is that solar PV is growing exponentially, and by 2020, photovoltaic power generation will account for about half of the annual new installed capacity." James said, "although solar photovoltaic everywhere in the world, but several key factors in promoting is is particularly important, including the outbreak of the emerging market demand, the development of European grid parity, and China, India and other developing countries of the roof of distributed resources in large-scale development."
By 2020, GTM Research Institute predicted that the annual new installed capacity of solar PV market will reach 135GW.
