Air pollution caused by coal block sunlight reduces the efficiency of solar panels

Journal according to the published in Nature Energy, air pollution caused by coal block sunlight. China is working to reduce dependence on coal-fired thermal power, photovoltaic capacity each year the world first, the installed capacity of 2017 accounted for more than half of the world.

from 2010 to 2017, China's photovoltaic power generation capacity from under one thousand mw to 130000 mw, and plans to reach 400000 to 2030 megawatts. However, photovoltaic power generation is also subject to the existing environmental problems: haze covered dark the sun, and led to a decline in the efficiency of photovoltaic power generation.

in the latest study, the federal institute of technology in Zurich, the researchers found that from 1960 to 2015, photovoltaic power generation potential fell by an average of 13%.

this effect is not in every place are the same. There are five provinces down 20 - generating potential 28%. This includes the eastern industrial center, including in the west of the high altitude & ndash; — These areas are less pollution will have a significant impact.

if the air quality in China back to 1950 levels, then 2016 photovoltaic capacity can produce 14 trillion megawatts of additional electricity. This means that to improve air quality will be able to improve the efficiency of photovoltaic power generation, to make it more competitive.
