Description
Technical field
The present invention relates to a kind of glued membrane, especially a kind of packaging adhesive film for solar cell.
Background technology
Solar energy is inexhaustible, nexhaustible clean energy resource, and the exhaustion and the earth environment pollution problem that utilize solar energy to solve the energy are the most direct and effective methods that present people propose.Development and use solar energy has become the strategic decision of the countries in the world sustainable development energy.In the energy resource structure of present China, coal, oil and natural gas have accounted for the overwhelming majority.Coal, oil and natural gas proportion are 93% in China's energy resource structures in 2000, and water power and nuclear power proportion are 7%, and are that the shared ratio of the new forms of energy of representative is extremely low with solar energy and wind energy.To the year two thousand twenty, China's GDP quadrupled than 2000, was taking into full account under technological progress, economic restructuring and the effective energy-conservation prerequisite, and demand for energy also will reach 25 ~ 3,300,000,000 tons of standard coals.If according to the present U.S. criterion calculation of 3 tons of oil consumptions per capita, the China's Oil consumption figure will be above the supply in 4,000,000,000 tons in the whole world at present.This will bring great challenge to the energy resources supply of China.Therefore, constantly improve in order to keep China's sustained economic growth and social civilization level, improve the energy efficiency except transforming mode of economic growth, making great efforts, new forms of energy such as development solar energy will become the emphasis of national energy development strategy.
In recent years, the height of energy future development is based in developed country, actively promotes the development of photovoltaic industry, puts into effect support policy, drops into significantly in advance, and the preemption techniques forward position makes photovoltaic industry become one of the fastest industry of the world development beginning of this century.Whole world solar cell yield is increased sharply to 7241MW in 2008 from 561MW in 2002, and annual growth reaches about 40%.The cumulative production of global solar battery in 2008 and installation amount have all reached 19.5GW.The US President Barack Obama announces, regenerative resource (comprising solar energy, wind energy and geothermal energy) electric power accounts for the ratio to 2012 of total electricity consumption year will bring up to 10%, bring up to 25% by 2025.In " plan of low-carbon (LC) social action " of Japan issue, propose the year two thousand twenty photovoltaic totally installation amount reach 14GW, reach 53GW to the year two thousand thirty.
