【摘要】：當(dāng)今世界面臨能源和環(huán)境兩大問題。太陽能因其巨大的能量供應(yīng)備受矚目。近年來,鈣鈦礦太陽能電池由于其原料廣泛,制備工藝簡單受到了廣泛關(guān)注�？昭▊鬏攲幼鳛殁}鈦礦電池的重要組成部分是當(dāng)前研究的熱點(diǎn)。本論文設(shè)計(jì)合成新型的有機(jī)小分子替代價格昂貴的spiro-OMeTAD作為空穴傳輸材料。并且研究其作為空穴傳輸層的鈦礦太陽能電池的光伏性能。論文首先設(shè)計(jì)合成了3種新型有機(jī)空穴傳輸材料(Q197、Q198,和Q205),對其化學(xué)結(jié)構(gòu)和物理性質(zhì)進(jìn)行了表征,并作為空穴傳輸材料應(yīng)用到鈣鈦礦太陽能電池中,研究了空穴傳輸分子的光物理性質(zhì)和電池的光伏性能與空穴傳輸分子結(jié)構(gòu)的關(guān)系。發(fā)現(xiàn)基于聯(lián)二萘酚的空穴傳輸材料表現(xiàn)了良好的光伏性能,開路電壓和光電流均高于聯(lián)二苯酚的空穴傳輸材料,聯(lián)二萘酚基團(tuán)增加了母核的共軛性,提高材料的導(dǎo)電性。在4-叔丁基吡啶(TBP)用量減少40%的條件下,Q197獲得最高的光電轉(zhuǎn)換效率,達(dá)到8.38%,接近在相同條件下spiro-OMeTAD的光電轉(zhuǎn)化效率(8.73%)。此外,給體結(jié)構(gòu)對空穴傳輸特性影響也很大,2,7-咔唑基-對(4-甲氧基-苯基)胺基明顯增加了電池的光電流,3,6-咔唑基-對(4-甲氧基-苯基)胺基則能提高電池的開路電壓。為了提高上述合成的空穴傳輸材料溶解性,改善成膜性能,在母核上引入芐基和己基側(cè)鏈,設(shè)計(jì)合成了Q221和Q222。研究發(fā)現(xiàn),基于側(cè)鏈為剛性較大的芐基化合物Q221電池的開路電壓達(dá)到945mV,光電轉(zhuǎn)化效率高達(dá)10.05%,與相同條件下spiro-OMeTAD相當(dāng)(10.06%)。當(dāng)摻雜劑(Li-TFSI和TBP)濃度減少50%時,仍表現(xiàn)出良好的導(dǎo)電性和空穴傳輸能力,獲得更高光電轉(zhuǎn)化效率(10.37%),優(yōu)于明星分子spiro-OMeTAD。芐基的引入不僅提高電池的光伏性能,還增強(qiáng)了電池的穩(wěn)定性,在持續(xù)光照200小時后,電池的光電轉(zhuǎn)化效率只降低50%。
[Abstract]:The world today faces two major problems: energy and environment. Solar energy has attracted much attention for its huge energy supply. In recent years, perovskite solar cells have attracted wide attention due to their wide range of raw materials and simple preparation process. As an important part of perovskite battery, hole transport layer is a hot research topic. In this paper, a novel organic small molecule is designed and synthesized to replace the expensive spiro-OMeTAD as a hole transport material. The photovoltaic performance of TIO _ 2 solar cells as a hole transport layer is also studied. Three new organic hole transport materials, Q197, Q198 and Q205, were designed and synthesized in this paper. Their chemical structure and physical properties were characterized and used as hole-transport materials in perovskite solar cells. The photophysical properties of hole-transport molecules and the relationship between the photovoltaic properties of the cells and the hole-transport molecular structure are studied. It is found that the hole transport material based on binaphthol has good photovoltaic performance, the open circuit voltage and photocurrent are both higher than those of the diphenol, and the conjugation property of the parent nucleus is increased and the conductivity of the material is improved by the binarynaphthol group. Under the condition of 40% reduction in the dosage of 4- tert-Ding Ji pyridine, the highest photoelectric conversion efficiency of Q197 was obtained, which was 8.38%, which was close to that of spiro-OMeTAD under the same conditions (8.73%). In addition, the donor structure has a great effect on the hole transport characteristics and the open circuit voltage of the battery can be improved by increasing the photocurrent of the battery. In order to improve the solubility and film-forming properties of the synthesized hole-transport materials, benzyl and hexyl side chains were introduced into the parent nucleus and Q221 and Q222 were designed and synthesized. It is found that the open circuit voltage of benzyl compound Q221 based on the relatively rigid side chain is 945mV, and the photoelectric conversion efficiency is 10.05, which is equivalent to that of spiro-OMeTAD under the same conditions. When the concentration of Li-TFSI and TBP is reduced by 50%, the dopants still exhibit good conductivity and hole transport ability, and obtain a higher photoelectric conversion efficiency of 10.37%, which is better than spiro-OMeTAD. The introduction of benzyl not only improves the photovoltaic performance of the cell, but also enhances the stability of the cell. After 200 hours of continuous illumination, the photovoltaic conversion efficiency of the cell is only reduced by 50%.
