【摘要】：染料敏化太陽能電池由于具有低廉的制作成本、特殊的結(jié)構(gòu)、較好的光電性能,越來越成為新型高效廉價(jià)太陽能電池領(lǐng)域的研究熱點(diǎn),自1991年以來,就引起了眾多研究者的廣泛興趣。因此,染料敏化太陽能電池在太陽能電池的研究中具有重要意義以及良好的應(yīng)用前景。但目前與得到人們認(rèn)可的硅太陽能電池相比,染料敏化太陽能電池的光電轉(zhuǎn)化效率仍然很低,距離走入人們的日常生活還有一段距離,因此提高染料敏化太陽能電池的光電轉(zhuǎn)化效率是目前太陽能電池研究的一個(gè)重要方面。本論文通過對(duì)天然染料敏化劑的選用和對(duì)準(zhǔn)固態(tài)電解質(zhì)的制備來提高染料敏化太陽能電池的光電性能。染料敏化太陽能電池具有“人造樹葉”的美稱,因此天然植物提取的染料作為光敏劑一直備受關(guān)注,本文采用了一種有效的天然染料的提取方法,從不同的植物中提取了十一種天然染料,包括蔬菜、水果、茶葉等,組裝成天然染料敏化太陽能電池,檢測(cè)其光電性能。并對(duì)這些天然染料進(jìn)行了UV-Vis光譜的測(cè)試。得到天然染料敏化太陽能電池的開路電壓(Voc)和短路電流密度(Jsc),其中從藍(lán)莓中提取的染料敏化的太陽能電池的光電性能最好,得到了1.11%的光電轉(zhuǎn)化效率。為了提高染料敏化太陽能電池的制作效率,本實(shí)驗(yàn)還采用了靜電噴鍍技術(shù),將染料噴鍍到工作電極上,這種技術(shù)不僅提高了染料敏化太陽能電池的制作效率,從檢測(cè)結(jié)果看,染料的吸光度也大大提高,為染料敏化太陽能電池效率的提高以及染料敏化太陽能電池的商業(yè)化發(fā)展奠定了基礎(chǔ)。電解質(zhì)是染料敏化太陽能電池的重要組成部分之一。準(zhǔn)固態(tài)電解質(zhì)介于液態(tài)電解質(zhì)和固態(tài)電解質(zhì)之間,不僅具有良好的光電性能,而且值得的準(zhǔn)固態(tài)染料敏化太陽能電池的穩(wěn)定性也較好。本論文采用丙烯酸-聚乙二醇共混聚合物為基體形成凝膠,通過吸附液態(tài)電解質(zhì)而形成準(zhǔn)固態(tài)電解質(zhì),并考慮了四個(gè)因素對(duì)準(zhǔn)固態(tài)電解質(zhì)光電性能的影響,這四個(gè)因素為不同的反應(yīng)時(shí)間、不同分子量的聚乙二醇、不同干燥時(shí)間和不同KI與12的摩爾比。
[Abstract]:The dye-sensitized solar cell due to its low production costs, special structure, good optical performance, has increasingly become a hotspot of new efficient cheap solar battery field, since 1991, it has aroused extensive interest of many researchers. Therefore, dye-sensitized solar cells has important significance and good application prospect in the research of solar energy the battery. But at present with silicon solar cells recognized compared to the photoelectric conversion efficiency of dye-sensitized solar cells is still low, the distance into people's daily life and a distance, thus improve the photoelectric conversion efficiency of the dye-sensitized solar cell is one of the important aspects of the current solar cell research. This paper based on selection of natural dyes and quasi solid electrolyte preparation to improve the photoelectric dye-sensitized solar cell The performance of dye-sensitized solar cells. With "artificial leaves" reputation, therefore extracted from natural plants dyes as photosensitizers have been of concern, this paper adopts a method for extraction of natural dyes effectively, from different plants were extracted eleven kinds of natural dyes, including vegetables, fruits, tea, natural dye sensitized assembly solar cell, detecting its optical and electrical properties of these natural dyes were tested. The UV-Vis spectra of the open circuit voltage natural dye-sensitized solar cell (Voc) and short-circuit current density (Jsc), wherein the photoelectric properties of dye sensitized solar cell extracted from blueberry in the best, the photoelectric conversion efficiency of 1.11%. In order to improve the production efficiency of dye-sensitized solar cell, this experiment also used electrostatic spraying technology, the dye sprayed onto the working electrode, this kind of technology can not only improve The production efficiency of dye-sensitized solar cell, the results show that the dye absorbance is greatly improved, laid the foundation for the commercial development of the efficiency of dye sensitized solar cell and dye-sensitized solar cell. The electrolyte is one of the most important parts of the dye-sensitized solar cell. Between the quasi solid electrolyte between solid and liquid electrolyte the electrolyte, not only has good photoelectric properties, and stability of quasi solid state dye-sensitized solar cells is also better. This paper adopts acrylic acid - polyethylene glycol blend polymerization as the matrix to form a gel formed by adsorption of liquid electrolyte, quasi solid electrolyte, and consider four factors on photoelectric properties of solid electrolyte, the four the factors for different reaction time, peg with different molecular weight, different drying time and different KI and 1 2 of the mole ratio.
