【摘要】：在能源需求持續(xù)增長(zhǎng)同時(shí)傳統(tǒng)化石燃料又日漸枯竭的今天,太陽(yáng)能以清潔、無(wú)污染和可再生的優(yōu)點(diǎn)獲得人們的廣泛關(guān)注。光伏發(fā)電是將太陽(yáng)能直接轉(zhuǎn)換成電能的技術(shù),發(fā)電成本高是制約光伏產(chǎn)業(yè)發(fā)展的主要因素。目前絕大多數(shù)是使用貴金屬銀制作太陽(yáng)電池的金屬電極,如果能夠用金屬銅來(lái)代替,將有助于降低光伏發(fā)電的成本進(jìn)而推動(dòng)光伏產(chǎn)業(yè)的發(fā)展。在本文中我們基于銅氨絡(luò)合物制備出了銅薄膜,有望在太陽(yáng)電池的電極上得到應(yīng)用。 本文首先以甲酸和氨水的混合溶液為電解液,電解陽(yáng)極銅制備出銅氨絡(luò)合物溶液,然后蒸發(fā)結(jié)晶干燥得到銅氨絡(luò)合物晶體。將銅氨絡(luò)合物晶體、有機(jī)載體和粘結(jié)劑按照一定配比混合用球磨的方法制成銅氨絡(luò)合物漿料,絲網(wǎng)印刷成膜。優(yōu)選銅氨絡(luò)合物含量為60%,優(yōu)選球磨時(shí)間為20h。最后在真空環(huán)境下燒結(jié),得到銅薄膜。 相關(guān)測(cè)試結(jié)果表明：銅氨絡(luò)合物由C、H、O、N和Cu五種元素組成,化學(xué)式為Cu(NH3)2(COOH)2,具有兩種可能的幾何異構(gòu)體。銅氨絡(luò)合物的熱分解溫度大約在150-170℃的范圍內(nèi),分解過(guò)程伴隨著吸熱。真空環(huán)境下熱處理得到的銅薄膜成分是銅單質(zhì)。 本文制備銅薄膜的方法熱處理溫度低,可以在多種襯底包括PI、PET等柔性襯底上成膜；絲網(wǎng)印刷成本低、效率高,能夠滿足大規(guī)模生產(chǎn)的需要；本文制備的銅薄膜除了代替銀用作太陽(yáng)電池的電極以外,在無(wú)線射頻識(shí)別系統(tǒng)以及印刷電路板等許多方面都有較好的應(yīng)用前景。
[Abstract]:Today, solar energy is widely concerned by the advantages of clean, pollution-free and renewable energy when the energy demand continues to grow and the traditional fossil fuels are increasingly dried up. PV power generation is a technology that directly converts solar energy into electric energy, and the power generation cost is the main factor that restricts the development of the photovoltaic industry. At present, most of the metal electrodes of the solar cell are made of noble metal silver, and if the metal copper can be used instead of the metal electrode, the cost of photovoltaic power generation can be reduced and the development of the photovoltaic industry can be promoted. In this paper, a copper thin film is prepared based on the copper-ammonia complex and is expected to be applied to the electrode of the solar cell. In this paper, the solution of copper-ammonia complex is prepared by using mixed solution of formic acid and ammonia water as electrolyte, and then the copper-ammonia complex crystal is obtained by evaporation and crystallization. a copper-ammonia complex slurry is prepared by mixing a copper-ammonia complex crystal, an organic carrier and a binder by a ball-milling method according to a certain proportion, and screen-printing to obtain the copper-ammonia complex slurry; the film preferably has a copper-ammonia complex content of 60%, preferably a ball milling time of 20, h. finally, sintering under a vacuum environment to obtain the copper thin The results show that the copper-ammonia complex is composed of five elements of C, H, O, N and Cu. The chemical formula is Cu (NH3)2 (COOH)2, which has two possible geometries. The thermal decomposition temperature of the copper-ammonia complex is in the range of about 150-170 & deg; C, and the decomposition process is accompanied the copper film component obtained by heat treatment under the vacuum environment is The method for preparing the copper thin film is low in heat treatment temperature, can be formed on a flexible substrate such as PI, PET and the like on a plurality of substrates; the screen printing cost is low, the efficiency is high, and the requirement of large-scale production can be met; and the copper thin film prepared by the method is used as a solar cell instead of silver in addition to the electrodes of the wireless radio frequency identification system and the printed circuit board,
