【摘要】：近數(shù)十年來(lái),全球人口迅速增長(zhǎng),工業(yè)發(fā)展越來(lái)越快,隨之伴隨的能源消耗越來(lái)越大,為了長(zhǎng)期可持續(xù)的發(fā)展,人們對(duì)可再生能源的需求就越來(lái)越強(qiáng)烈。后來(lái),基于ABX3 (A=CH3NH3, B=Pb, Sn, and X=Cl, Br, I)結(jié)構(gòu)的有機(jī)鈣鈦礦,因?yàn)槠渫怀龅膬?yōu)點(diǎn)(1光捕獲率很高。2主要原料便宜,儲(chǔ)存充足。3可以由低溫旋涂技術(shù)加工。4光吸收后,產(chǎn)生電子容易,能量損耗低等)逐漸吸引了人們的注意并得以迅速的發(fā)展。盡管如此,鈣鈦礦太陽(yáng)能電池因?yàn)槠鋵?duì)氧氣和濕度很敏感,晶體結(jié)構(gòu)易發(fā)生改變等原因,使得對(duì)鈣鈦礦太陽(yáng)能電池的制備工藝和結(jié)構(gòu)優(yōu)化提出了更高的要求。本文針對(duì)上述問(wèn)題,主要研究了鈣鈦礦太陽(yáng)能電池的溶液體系,電荷傳輸層的制備等方面對(duì)鈣鈦礦太陽(yáng)能電池效率的影響,具體的工作如下：(1)改善鈣鈦礦薄膜的表面形貌是提高器件PCE的主要途徑,文獻(xiàn)中通常采用在前驅(qū)體溶液中加入固體添加劑的手段實(shí)現(xiàn),如CH3NH3Cl、NH4Cl等。我們發(fā)現(xiàn)基于Pbl2的兩步法制備鈣鈦礦太陽(yáng)能電池,在鈣鈦礦前驅(qū)液中加入適量的PbCl2,同樣可達(dá)到改善效率的目的,隨著PbC12的量的增多,器件的效率得到了顯著的提高,通過(guò)對(duì)不同比例的PbCl2:Pbl2進(jìn)行研究,最終發(fā)現(xiàn)最優(yōu)化的比例關(guān)系是PbCl2:Pbl2=1:1(摩爾比),效率達(dá)到了9.5%。(2)GBL和DMSO混合溶劑的應(yīng)用。在制備鈣鈦礦太陽(yáng)能電池的過(guò)程當(dāng)中溶劑對(duì)于鈣鈦礦層的形成和形貌控制騎著至關(guān)重要的作用。鑒于DMSO和Pbl2有較強(qiáng)的相互作用,在基于MAPbI3的一步旋涂法制備鈣鈦礦電池的過(guò)程中,通過(guò)將DMSO和GBL以一定的比例混合,最終發(fā)現(xiàn)DMSO對(duì)鈣鈦礦層形貌的改善有很大幫助。(3)不同退火溫度的嘗試。關(guān)于鈣鈦礦太陽(yáng)能電池的研究,之前文獻(xiàn)中基本上都是采用兩步旋涂法,分別將鹵化鉛和甲基碘化氨溶液旋涂在電荷傳輸層上退火加熱,從而形成鈣鈦礦層。但是一步旋涂法的出現(xiàn)不僅大大的簡(jiǎn)化了實(shí)驗(yàn)過(guò)程,還因?yàn)殁}鈦礦的反應(yīng)物質(zhì)在前驅(qū)液中充分混合,從而使得鈣鈦礦層的成膜更加完整,最大限度的控制了鹵化鉛和甲基碘化銨的過(guò)量,從而有效的提高了電池的效率。所以研究不同退火溫度下,基于一步旋涂法制備鈣鈦礦太陽(yáng)能電池有很重要的意義。
[Abstract]:In recent decades, the rapid growth of the global population, industrial development more and more quickly, then with the growing energy consumption, in order to long-term sustainable development, demand for renewable energy is more and more intense. Later, based on the ABX3 (A=CH3NH3, B=Pb, Sn, and X= Cl, Br, I) organic perovskite structure and because of its outstanding advantages (1 light capture the main raw material of a high rate of.2 is cheap,.3 can be absorbed by the low temperature storage sufficient spin coating processing technology.4 light, electrons easily, low energy consumption) gradually attracted people's attention and to rapid development. However, because the perovskite type solar cell sensitive to oxygen and moisture, cause the crystal structure is easy to be changed, the preparation process and optimize the structure of perovskite solar cell has put forward higher requirements. Aiming at the above problems, the main research of the perovskite solar power The solution pool, affect the charge transport layer preparation of perovskite solar cell efficiency, the specific work is as follows: (1) improve the surface morphology of Perovskite Thin Films is an important way to improve the PCE device, the literature generally by adding solid additives in the precursor solution method, such as CH3NH3Cl, NH4Cl. We found that the two step method of Pbl2 perovskite solar cell based on adding PbCl2 in perovskite precursor solution, also can improve efficiency, with the increase in the amount of PbC12, the device efficiency has been significantly improved, based on the research of different proportion of PbCl2:Pbl2, finally found the proportion optimization the relationship between PbCl2:Pbl2=1:1 (molar ratio), the efficiency reached 9.5%. (2) using GBL and DMSO mixed solvent. The solvent for the perovskite layer in the process of preparation of perovskite solar cell The formation and morphology control of riding a vital role. In view of the fact that DMSO and Pbl2 have a strong interaction, based on a spin coating preparation of perovskite MAPbI3 battery in the process of using DMSO and GBL mixed with a certain proportion, finally found improvement on the perovskite morphology of DMSO (3) are of great help. Try different annealing temperature. Research on perovskite solar cell, before in the literature are basically using the two step spin coating, respectively lead halide and methyl iodide in ammonia solution was spin coated on charge transport layer annealing, thus forming a perovskite layer. But there is a step in the spin coating method not only simplifies greatly during the experiment, but also because the reaction material perovskite mixing in the precursor solution, which makes the film perovskite layer is more complete, the maximum control of excessive lead halide and ammonium methyl iodide, thereby effectively. The efficiency of the battery is higher. So it is of great significance to study the perovskite solar cell based on one step spin coating method at different annealing temperatures.
