Background technology
Flexible substrate Copper Indium Gallium Selenide (Cu (In, Ga) Se
2, being called for short CIGS) and to have quality higher than power for thin film solar cell, the advantages, particularly flexible substrate CIGS hull cell such as capability of resistance to radiation is strong, good stability.Its quality is more general than power is greater than 600W/kg, and battery component is applicable to volume to volume preparation and single-chip integration, in producing in batches and reducing costs, have very large potentiality, and range of application more extensively (compared to rigid substrate).
The preparation of Copper Indium Gallium Selenide flexible thin-film solar cell component adopts the mode of etching to realize usually, and etching can adopt the methods such as photoetching, Mechanical lithography, laser ablation, and in the preparation of thin film solar battery module, laser ablation has clear superiority.Laser ablation is a kind of selective etch without mask, greatly can simplify the etching technics in the preparation of inline assembly.The width of general laser ablation groove is 30-80mm, in inline assembly preparation, adopt laser etching process effectively can reduce the dead zone area of assembly.
In the manufacture of CIGS thin-film solar cell, depth-selectiveness laser etching process comparative maturity on the CIGS thin-film solar cell of glass substrate, and also there are a lot of technological difficulties in the depth-selectiveness laser ablation of flexible CIGS thin-film solar cell.This is because flexible CIGS thin-film solar cell rete is very thin and easily curling, the layers of material of battery will be etched respectively, and the rete do not damaged below it, this is to the uniformity of each layer film thickness, and in etching process, the evenness of battery, the stability of laser power etc. require very high.Be different from the CIGS thin-film solar cell of glass substrate, the structure unification not yet that the inline assembly of current flexible CIGS thin-film solar cell adopts.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of preparation method of flexible thin-film solar cell component, and object prepares flexible CIGS thin-film solar cell assembly by this technology.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of preparation method of flexible thin-film solar cell component, utilizes the method for laser ablation, complete P1, P2, P3 rule, then in P1 raceway groove, inject insulating cement, finally use silk screen printing by two sub-serial battery.
Specifically, the preparation method of described flexible thin-film solar cell component, comprises the following steps:
Step 1. is placed on absorption platform by manual type by complete for cell, ensures that cell adsorbs completely, has avoided rough abnormity point position;
Step 2., in laser scoring operations system, determines laser parameter, scratches battery Mo layer and forms raceway groove with upper part, then use the laser of 1064nm to carry out cover score line to raceway groove, scratch Mo layer;
Step 3. carries out the positive pole that each sub-battery is exposed in P2 line on P1 line right side: use 1064nm laser incising eating away Mo layer with upper part but do not scratch Mo layer;
Step 4. carries out the negative pole that P3 line separates each sub-battery on P2 line right side: use 1064nm laser to scratch tco layer;
Step 5. injects insulating cement in P1 raceway groove: use point gum machine to inject insulating cement at P1 raceway groove and prevent self short circuit of sub-battery;
Step 6. is by several sub-serial battery: use silk screen printing to be connected to form with the negative pole of last sub-battery by the positive pole of each sub-battery and connect.
The invention has the beneficial effects as follows:
1. present invention employs wavelength and be respectively 1064nm laser as scoring tool.Meanwhile, be the attached platform of vacuum bottom it, what this just made that flexible hull cell can be smooth is attracted on table top.
