【摘要】：采用超聲波輔助乙二醇還原硝酸銀的工藝對(duì)玻璃粉進(jìn)行活化處理,以硝酸銀為銀源,單寧為還原劑,在室溫下用化學(xué)鍍法制備鍍銀玻璃粉,并將此復(fù)合粉末用于晶硅太陽(yáng)能電池的導(dǎo)電銀漿中。利用SEM和EDS對(duì)復(fù)合粉末、太陽(yáng)能電池電極表面和截面進(jìn)行形貌觀察和成分分析,利用XRD和DSC對(duì)玻璃粉分別進(jìn)行物相分析和熱分析。結(jié)果表明:在設(shè)定的反應(yīng)條件下,當(dāng)硝酸銀與玻璃粉的初始質(zhì)量比為0.09時(shí),銀鍍層均勻;玻璃粉表面鍍覆納米銀可降低玻璃粉軟化溫度、提高電極厚膜的致密度、并在銀硅界面沉積更多銀晶體,使電池的光電轉(zhuǎn)化效率從17.551%提高至17.711%。
[Abstract]:Glass powder was activated by ultrasonic assisted reduction of silver nitrate with ethylene glycol. Silver nitrate was used as silver source and tannin was used as reducing agent to prepare silver coated glass powder by electroless plating at room temperature. The composite powder was used in conductive silver paste of crystalline silicon solar cell. The surface and cross section of composite powder and electrode were observed and analyzed by SEM and EDS. The phase analysis and thermal analysis of glass powder were carried out by XRD and DSC. The results showed that the silver coating was uniform when the initial mass ratio of silver nitrate to glass powder was 0.09 under the set reaction conditions. The coating of nano-silver on glass powder can reduce the softening temperature of glass powder, improve the density of thick film of electrode, and deposit more silver crystals at the interface of silver-silicon. The photoelectric conversion efficiency of the battery is increased from 17.551% to 17.711.1%.
