The principal benefits that concentration photovoltaic solar can electricity generation system be looked for is on condensation photovoltaic battery sheet, to obtain the high density sunray that converges from lens.
Condensation photovoltaic battery sheet coagulates slurry through tin cream or heat-conductivity conducting or heat-conductivity conducting glue is fixed on the opto-electronic conversion acceptor circuit plate; Thus; Because the error that forms in position components design error and the assembling process; Occurring light that optical element converges easily can not focus on the condensation photovoltaic battery sheet and after a period of time of coming into operation fully; Expanded by heating coefficient that parts material difference causes is different, causes problems such as the position of condensation photovoltaic battery sheet changes, and causes to promote difficulty and increase.
Summary of the invention
The purpose of this invention is to provide a kind of method that strengthens condensation photovoltaic battery sheet positioning accuracy; This method is to overcome the deficiency of prior art; Realize that circuit board is not oxidized and on condensation photovoltaic battery sheet, receive the sunray that converges fully; Thereby improve photovoltaic cell capable of generating power efficient and generated output, reduce cost of electricity-generating.
In order to realize above-mentioned technical purpose, the present invention has following process and step:
A) will be positioned at etching multiple tracks etching tank on the copper-clad base plate above the condensation photovoltaic opto-electronic conversion acceptor circuit plate, the method for etching etching tank is following: (1) is at first cleaned copper-clad base plate; (2) on Copper Foil, coat photoresist; (3) copper-clad base plate is placed mask aligner, paint the plate aligning with the light that has straight line and broken line etch pattern and carry out photoetching; (4) after the copper-clad base plate after will making public developed, bath dried, and post bake is handled then; (5) place the etching machine to carry out dry method or wet etching copper-clad base plate; (6) then with the processing of removing photoresist of the copper-clad base plate after the etching;
B) be divided on the two-part Copper Foil at the above-mentioned copper-clad base plate groove that is corroded, be taken up in order of priority to apply nickel dam and gold layer, just formed condensation photovoltaic opto-electronic conversion acceptor circuit plate;
C) in the condensation photovoltaic battery panel region of above-mentioned condensation photovoltaic opto-electronic conversion acceptor circuit plate, starching perhaps with fixed attention with tin cream or heat-conductivity conducting, heat-conductivity conducting glue deposits or applies this battery panel region through screen printing screens or some glue mode;
D) condensation photovoltaic battery aligning is positioned in the cell area of the condensation photovoltaic opto-electronic conversion acceptor circuit plate that has coating material; And adopt stoving process that coating material is solidified, reach the seamless bonding of photovoltaic cell and circuit board.
Advantage of the present invention and good effect are: 1. each layer of circuit base material combines dexterously, but realized that entire circuit plate heatproof reaches 120 ℃, and the protective circuit plate is not oxidized simultaneously; The photovoltaic cell sheet is more accurately located in the design of 2 circuit substrates, guarantees to receive fully the sunray of party, thereby reaches the raising generated output, reduces cost of electricity-generating.
