【摘要】：染料敏化太陽能電池(DSSC)是第三代薄膜太陽能電池中發(fā)展的較為成熟的太陽能電池。與傳統(tǒng)的硅晶太陽能電池相比,它具有成本低、來源廣泛、制備工藝簡(jiǎn)單等優(yōu)點(diǎn),所以近些年來備受關(guān)注。但是其自身也存在著一定的缺陷,如現(xiàn)在公認(rèn)的使用效果最好的N719染料制備過程比較復(fù)雜,且釘金屬價(jià)格昂貴,有機(jī)染料對(duì)近紅外光區(qū)吸收相對(duì)較弱,染料激發(fā)壽命短、穩(wěn)定性差等。所以,研究和開發(fā)新的材料來代替有機(jī)染料是DSSC發(fā)展的一個(gè)方向和趨勢(shì)。 本課題研究重點(diǎn)為利用Sb2S3納米粒子代替有機(jī)染料作為敏化劑制備TiO2-Sb2S3共敏化基太陽能電池,并對(duì)其性能和效率進(jìn)行研究探討；制備層狀鈣鈦礦型有機(jī)-無機(jī)金屬鹵化物薄膜并與多孔Ti02組成復(fù)合光陽極,研究復(fù)合光陽極對(duì)增加電子捕獲能力,抑制光生電子-空穴的復(fù)合及提高光電轉(zhuǎn)換效率的意義。 主要研究內(nèi)容包括以下三個(gè)方面： (一)對(duì)染料敏化太陽能電池制備過程中最佳條件的選擇研究。通過利用不同尺寸的Ti02漿料制備光陽極,不同的光陽極后處理方法,不同的染料以及不同的封裝方法制備出不同的DSSC,經(jīng)過對(duì)比研究,得出制備DSSC的最佳條件為：采用20nm TiO2納米顆粒與200nm TiO2納米顆粒組成復(fù)合薄膜電極；復(fù)合電極使用TiCl4或Ti02溶膠后處理；浸泡含有鵝去氧膽酸共吸附劑CDCA的N719染料；使用雙面膠封裝。在最佳條件下制備的染料敏化太陽能電池的光電流密度為13.10mA·cm·2,光電轉(zhuǎn)化效率為5.4%,較之前提高了2%-3%左右。 (二)采用化學(xué)沉積法制備Sb2S3納米粒子,并與多孔Ti02組成TiO2-Sb2S3復(fù)合光陽極,分別以P3HT和固態(tài)電解質(zhì)CuSCN作為空穴傳輸層,以Ag為對(duì)電極組裝Sb2S3量子點(diǎn)敏化太陽能電池。使用XRD、SEM、TEM、UV-Vis等對(duì)復(fù)合電極進(jìn)行表征測(cè)試。測(cè)量出FTO/TiO2/Sb2S3/P3HT/PEDOT/Ag結(jié)構(gòu)太陽能電池和FTO/TiO2/Sb2S3/CuSCN/Ag結(jié)構(gòu)太陽能電池光電轉(zhuǎn)化效率分別為0.34%和0.47%。 (三)分別使用旋涂法和分步沉積法在多孔Ti02薄膜上制備層狀鈣鈦礦型有機(jī)-無機(jī)金屬鹵化物薄膜,并以spiro-OMe-TAD作為空穴傳輸層,以Ag為對(duì)電極,分別組裝不同的層狀鈣鈦礦型有機(jī)-無機(jī)雜化太陽能電池。使用XRD、SEM、EDX、 TEM、UV-Vis、TG-DSC等對(duì)復(fù)合電極進(jìn)行表征測(cè)試。采用旋涂法制備的FTO/TiO2/CH3NH3PbI2Cl/Spiro-OMe-TAD/Ag電池光電轉(zhuǎn)化效率分別為0.28%和0.71%。采用分步沉積法制備的FTO/TiO2/CH3NH3PbI2Cl/Spiro-OMe-TAD/Ag結(jié)構(gòu)電池、FTO/TiO2/CH3NH3PbI3/Spiro-OMe-TAD/Ag結(jié)構(gòu)電池光電轉(zhuǎn)化效率分別為1.13%和1.80%。
[Abstract]:The dye-sensitized solar cell (DSSC) is a solar battery more mature development of the third generation thin film solar cells. Compared with the traditional silicon solar cell, it has the advantages of low cost, wide source, has the advantages of simple preparation process, so in recent years much attention. But it also has some defects, process N719 dye preparation such as it is now recognized as the best complex, and expensive metal nail, organic dye and near-infrared light absorption dye is relatively weak, short life, poor stability and so on. Therefore, the research and development of new materials to replace the organic dye is a direction and trend of the development of DSSC.
The research focuses on the use of Sb2S3 nanoparticles instead of organic dyes as sensitizers for preparation of TiO2-Sb2S3 based co sensitized solar cells, and to study its performance and efficiency; preparation of layered perovskite type organic-inorganic composite film and metal halide light anode and porous Ti02, of complex light anode to increase electron capture ability. Inhibition of electron - hole recombination and improve the photoelectric conversion efficiency significantly.

(a) to select the best condition in the process of preparation of dye-sensitized solar cell system. By using different sizes of Ti02 slurry preparation of light anode, light anode after different processing methods, different dyes and different packaging methods were prepared by different DSSC, through the comparative study, the optimum conditions for the preparation of DSSC the TiO2 is using 20nm nanoparticles and 200nm TiO2 nanoparticles composite film electrode; TiCl4 or Ti02 sol after using the composite electrode; N719 dye containing chenodeoxycholic acid coadsorbent CDCA; use double-sided adhesive package. The photocurrent density of dye-sensitized solar cell prepared under the optimum conditions for 13.10mA. Cm - 2, the photoelectric conversion efficiency is 5.4%, higher than the previous 2%-3%.
(two) preparation of Sb2S3 nanoparticles by chemical deposition method, and the composition of TiO2-Sb2S3 composite photoanode and porous Ti02, respectively by P3HT and CuSCN as solid electrolyte with Ag as hole transport layer, the electrode assembly of Sb2S3 quantum dot sensitized solar cell. The use of XRD, SEM, TEM, UV-Vis and other characterization testing of composite electrode is measured. The photoelectric conversion efficiency of FTO/TiO2/Sb2S3/P3HT/PEDOT/Ag solar cell structure and FTO/TiO2/Sb2S3/CuSCN/Ag structure of solar cell was 0.34% and 0.47%. respectively.
(three) using spin coating method and step deposition method for preparing layered perovskite type organic-inorganic metal halide film on the porous Ti02 film, and spiro-OMe-TAD as hole transport layer, using Ag as the electrode, were assembled perovskite type layered organic-inorganic hybrid of different solar cells. The use of XRD, SEM. EDX, TEM, UV-Vis, TG-DSC were characterized by FTO/TiO2/CH3NH3PbI2Cl/Spiro-OMe-TAD/Ag test of composite electrode. The photoelectric conversion efficiency of cell prepared by spin coating are respectively 0.28% and 0.71%. using FTO/TiO2/ CH3NH3PbI2Cl/Spiro-OMe-TAD/Ag structure cell deposition step, the photoelectric conversion efficiency of FTO/TiO2/CH3NH3PbI3/Spiro-OMe-TAD/Ag cell structure were 1.13% and 1.80%.
