Description
Technical field
The invention belongs to solar cell package material and preparation field thereof, particularly a kind of packaging adhesive film for solar cell and preparation method thereof.
Background technology
When the Nonrenewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem becomes the bottleneck of restriction international community Economic development day by day, increasing country comes into effect " sunlight program ", develops solar energy resources, seeks the new power of Economic development.Some high-caliber core research institutions of Europe also start to turn to renewable energy source.Under the promotion of international photovoltaic market great potential, the solar cell production of various countries falls over each other to drop into huge fund, and expanding production, to strive one seat.
Solar energy power generating can occupy the important seat of world energy sources consumption in the near future, not only wants Substitute For Partial conventional energy resources, and will become the main body of world energy supplies.Expect the year two thousand thirty, renewable energy source will account for more than 30% in total environment protecting and power-saving solar energy structure, and the accounting of solar energy power generating in world's total electricity supply also will reach more than 10%; To the year two thousand forty, renewable energy source will account for the more than 50% of total energy consumption, and solar energy power generating will account for the more than 20% of total electricity; To 21 century Mo, renewable energy source will account for more than 80% in energy structure, and solar electrical energy generation will account for more than 60%.These numerals are enough to demonstrate the development prospect of photovoltaic industry and in the important strategic position of energy field.This shows, solar cell market outlook are wide.
