Background technology

Since 21 century, global Energy Consumption sharply rises, and traditional fossil energy is day by day exhausted, and energy problem and environmental problem are increasingly becoming two big Important Problems of global concern. Under the pressure of the pressure of sustainable development, solar photovoltaic industry is listed in the emphasis that regenerative resource develops by each major country one after another. Becoming the second in the world economy along with China, in October, 2013, China's petroleum import in October amount reaches every day 6,300,000 barrels, exceedes the every day 6,240,000 barrels of the U.S., and replacing the U.S. first becomes global maximum net import of oil state. 2013, the external dependence degree of CNPC and natural gas respectively reached 58.1% and 31.6%, and China has become global the third-largest natural gas consumption state. Traditional fossil energy is increasingly difficult to meet the thriving demand of Chinese national economy. In 20 years of past, the artificial CO2 emissions in the whole world nearly about 75% derive from combustion of fossil fuel. Therefore, no matter being the energy development angle from low-carbon environment-friendly, still comply with Industry Structure upgrading and transition pressure, China must accelerate development New Energy Industry.

Solar energy belongs to clean reproducible energy. According to " Europe renewable energy technologies strategic plan " that EU Committee proposes, to the year two thousand twenty, solar energy will account for the 15% of European Union's electricity needs. 2010, USDOE developed planning, and plan is to the year two thousand thirty, and solar energy accounts for the 10%��15% of total energy consumption figure. Generating electricity from worldwide solar energy and tide energy aggregate net and take temperature, China is 3,000,000,000 kilowatt hours, and Germany is 19,000,000,000 dry watt-hours, and Italy is 10,700,000,000 dry watt-hours, and Spain is 9,100,000,000 kilowatt hours, and Japan is 3,800,000,000 kilowatt hours. Following China water power growth space is limited, and nuclear energy exists unsafe factor. Fossil energy will be risen by energy-saving and emission-reduction committed cost, the wide market of solar energy power generating.

In order to obtain required electric current, voltage and output, in current photovoltaic industry, it is necessary to form, through techniques such as stacking, lamination, encapsulation, the practical application product that power supply output can be become after solar module after being connected by solar battery sheet.In crystal silicon solar battery component manufacture process, first with interconnector, solar battery sheet must be welded into solaode string, then by multiple solaode string marshallings, next being welded by the interconnector that the end of busbar with multiple solaode strings is stretched out, electric current can be collected in rosette outwardly to provide electric power by busbar.

The material of busbar is generally painting stannum copper strips, and shape is generally L-shaped, and limit and the interconnection of solaode string, shorter limit and rosette that L-shaped busbar is wherein longer interconnect. The manufacture method of L-shaped busbar is: preparing two sections of busbars, be then placed on the stainless steel mould plate of track, two sections of busbars partly overlap, and becomes 90 degree of placements, then welds with electric cautery and solder stick again. The shortcoming of this production method is: due to needs by busbar cutting, partly overlap 90 degree of placements, the operation therefore welded is more, and welding efficiency is low, and is easily generated overlap in welding process.
