Background technology
At present, the development of solar battery technology mainly has two kinds of different routes, and one kind is by being adulterated to monocrystalline silicon
The materials such as boron, phosphorus, antimony formation P-N junction, forms hole-electron pair, and then formed in one in electric field, this kind under direct sunlight
Although solar cell prepared by technology possesses good transformation efficiency and long-term reliability, due to monocrystalline silicon battery raw material
Expensive and battery series connection complex process, cost is higher when installing large area photovoltaic module.Another technology is by heavy
Product multi-lager semiconductor thin-film material forms solar cell on substrate, and solar cell prepared by the technology is to materials demand

Metal is used as substrate, it is allowed to which what is continuously rotated is treated as one of scheme of raising thin-film solar cells efficiency.But, although
Metal substrate can bear high temperature process, but the series connection of battery is still extremely difficult, because metal substrate is conductive, phase
The contact of the metal substrate of adjacent battery unit can cause short circuit.For this problem, many solutions are also suggested, and the U.S. is special
Sharp US4746618 discloses a kind of series connection method of solar cell, using stainless steel as substrate, realizes the film of volume to volume
Deposition and battery series connection；But the preparation process of this method includes multiple cuttings, deposition and manufacturing procedure, cost is very high；The U.S. is special

Divide semi-conducting material and top electrode, expose a part of metal substrate, exposed metal substrate is just as the contact with adjacent cell
Region, realizes the series connection of battery, and this kind of method allows high-temperature process, can also realize large-scale production, but be due to go
Except the semi-conducting material on metal substrate causes cost to raise, the wasting of resources, process complications and performance accuracy is difficult to control to.
