The utility model content
At the shortcoming of above-mentioned flexible solar battery, the technical problems to be solved in the utility model provides a kind of simple in structure, flexible thin-film solar cell that can improve electric current to a great extent.
For addressing the above problem, the utility model adopts following technical scheme:
Flexible thin-film solar cell, P-I-N functional layer at the bottom of comprising stainless steel lining, on being plated at the bottom of the stainless steel lining, be plated in the transparent conducting film on the functional layer and be plated in stainless steel lining at the bottom of the band that confluxes of an end, the hot pressing that is arranged in parallel of some carbon lines connects the band that confluxes in conducting film and carbon line one end, and wherein functional layer is followed successively by N layer, I layer and P layer from the bottom to top.
Described carbon line is plating carbon silver line, makees lead with silver-colored line and can reduce resistance, and the probability of battery short circuit when silver plating carbon can utilize the flexibility of carbon dust to make minimizing hot pressing again, protection silver does not cure; Spacing between adjacent two carbon lines is 3 mm ~ 10 mm, has not both blocked most of light, again enough reduction the threshold values of resistance.
Thickness at the bottom of the described stainless steel lining is 0.1 mm ~ 0.9 mm, has guaranteed the electric current maximization.
Hot pressing layer of transparent diaphragm also on the carbon line, fixing carbon line not only can also prevent that impurity such as dust from entering battery, and the battery surface dust of being convenient to flip, and prolongs the useful life of battery.
Described P-I-N functional layer can be any one solar cell functional layer.
Fixed by the electric current that nesa coating is drawn, under the prerequisite that the area of battery changes, it is more big area to occur, and resistance is more big, the problem that electric current is more little.The utility model is some carbon lines of hot pressing on nesa coating, and electric current flows through and comes together in the band that confluxes from carbon line, greatly reduces resistance, has increased electric current.
