【摘要】：太陽能是一種可再生清潔能源。太陽能電池是利用太陽能的重要途徑,而銀漿料是制造太陽能電池的關(guān)鍵原材料,銀漿料的品質(zhì)對制備出的電池的性能起著關(guān)鍵性的作用,制備出優(yōu)質(zhì)的銀漿料是制造高效低成本太陽能電池的關(guān)鍵。目前國內(nèi)生產(chǎn)太陽能電池所用的銀漿大部分都是依賴進(jìn)口,且大部分太陽能電池使用的銀漿為含鉛銀漿。因此,為了擺脫依賴進(jìn)口漿料的命運和緩解環(huán)境污染問題,自主研制出各方面性能都滿足太陽能電池使用要求的正面無鉛銀漿料,十分迫切且意義重大。 本文主要研究了太陽能電池正面無鉛銀漿組成原料的制備,制備出無鉛銀漿并對其進(jìn)行了相關(guān)性能的研究,討論了銀漿的成分配比及燒結(jié)工藝對其性能的影響。 采用熔融法制備無鉛玻璃粉,選用Bi2O3、SiO2、B2O3、Al2O3、TiO2、NaF、ZnO和Sn02氧化物作為玻璃粉的主要成分,并對制備出的玻璃粉進(jìn)行轉(zhuǎn)變溫度和耐酸耐堿性測試,確定轉(zhuǎn)變溫度和化學(xué)穩(wěn)定性較優(yōu)的玻璃粉的成分配比。使用液相還原法制備銀粉,討論反應(yīng)pH和AgNO3溶液的滴加速度對銀粉粒徑大小及其形貌的影響,結(jié)果顯示pH值為7、AgNO3溶液的滴加速度為5ml/min左右時制備出的銀粉性能較優(yōu)；制備出性能良好的滿足太陽能電池銀漿使用要求的有機(jī)載體。 使用制備出的銀粉、玻璃粉和有機(jī)載體配制太陽能電池正面導(dǎo)電銀漿,討論了玻璃粉含量、銀粉的粒徑和形貌、兩種不同粒徑和形貌的銀粉混合加入、銀粉中片銀的含量對銀膜性能的影響,還研究了銀膜的燒結(jié)工藝對其性能的影響。試驗結(jié)果表明：綜合考慮銀膜的方阻和附著力,當(dāng)銀漿成分為玻璃粉含量5%,銀粉含量80%(2gm的片狀銀粉和2μm球形銀粉按質(zhì)量分?jǐn)?shù)5：3混合)時,燒結(jié)工藝為燒結(jié)峰值溫度760℃時保溫7min的條件下,所得銀膜性能較優(yōu)。此時,銀膜方阻為3.7mΩ/,銀膜附著力為7.6N。
[Abstract]:Solar energy is a renewable and clean energy source. Solar cell is an important way to make use of solar energy, and silver paste is the key raw material to make solar cell. The quality of silver paste plays a key role in the performance of the prepared cell. Preparation of high quality silver paste is the key to manufacturing high efficiency and low cost solar cells. At present, most of the silver paste used in domestic solar cell production depends on imports, and most of the silver paste used in solar cells is leaded silver paste. Therefore, in order to get rid of the fate of relying on imported slurry and alleviate the problem of environmental pollution, we have developed a lead-free silver paste which can meet the requirements of solar cells in all aspects, which is very urgent and of great significance. In this paper, the preparation of lead-free silver paste on the front of solar cell was studied, and the properties of lead-free silver paste were studied. The effects of composition ratio of silver paste and sintering process on its properties were discussed. Lead-free glass powder was prepared by melting method. Bi2O3SiO2B2O3Al2O3Al2O3TiO2Nafu ZnO and Sn02 oxides were selected as the main components of glass powder. The transition temperature and acid resistance and alkali resistance of the prepared glass powder were measured. Determine the composition of glass powder with better transition temperature and chemical stability. Silver powder was prepared by liquid phase reduction method. The effects of reaction pH and droplet acceleration of AgNO3 solution on the size and morphology of silver powder were discussed. The results showed that the silver powder with pH value of 7% Agno _ 3 solution was better than that of 5ml/min solution. An organic carrier with good performance to meet the requirements of silver paste for solar cells was prepared. Silver powder, glass powder and organic carrier were used to prepare conductive silver paste on the front of solar cell. The content of glass powder, particle size and morphology of silver powder were discussed. Two kinds of silver powder with different particle size and morphology were mixed in. The effect of silver content in silver powder on the properties of silver film was also studied. The results show that considering the square resistance and adhesion of silver film, when the composition of silver paste is glass powder content 5, silver powder content 80%(2gm flake silver powder and 2 渭 m spherical silver powder are mixed at 5:3 by mass fraction. The best silver film properties were obtained when the sintering temperature was 760 鈩，
