【摘要】：研究了三種銀合金基夾層結(jié)構(gòu)透明導(dǎo)電薄膜的光電性能以及銀鈦合金夾層結(jié)構(gòu)透明導(dǎo)電薄膜(GATG)的耐熱性能及其在聚合物太陽能電池(OSCs)中的應(yīng)用。研究以四氟化碳等離子體修飾PEDOT:PSS為空穴傳輸層的鈣鈦礦太陽能電池(PSCs);探索基于氧化鋅電子傳輸層的反型PSCs電池工藝。具體內(nèi)容如下:1.研究了銀鋁、銀鉻、銀鈦三種銀合金夾層結(jié)構(gòu)透明導(dǎo)電薄膜(即GZO/Ag合金/GZO)的光電性能。GZO/AgTi/GZO(GATG)薄膜的光透過率和方塊電阻分別達(dá)到86%和5Ω/sq,表現(xiàn)最優(yōu)。此外,GATG具有耐高溫的特性,其耐高溫的原因是:在銀沉積的過程中,鈦原子形成了鈦氧化物包裹在銀顆粒表面,抑制銀原子受熱的遷移團(tuán)聚,提高銀合金層的熱穩(wěn)定性。2.研究了基于GATG的氧化鋅反型OSCs電池性能,電池功率轉(zhuǎn)換效率達(dá)到9.2%。在相對濕度69%,紫外光照射20分鐘以后,基于GATG的OSCs器件保持著原始效率的59%,而基于銦錫氧化物透明電極(ITO)的OSCs電池只有原始效率的23%。導(dǎo)致電池退化的原因是氧化鋅具有光催化效應(yīng),加速電子層和活性層界面的退化,使得器件開路電壓等性能的明顯下降,而采用GATG電極的電池,GATG導(dǎo)電薄膜阻擋紫外光到達(dá)活性層,抑制了 ZnO的光催化效果,使得電池紫外耐受性能得到明顯提升。3.利用四氟化碳等離子體處理修飾的PEDOT:PSS作為空穴傳輸層,采用兩步法制作鈣鈦礦太陽能電池,研究電池的光伏性能。研究表明,等離子體處理PEDOT:PSS表面后,電池的電流遲滯現(xiàn)象嚴(yán)重,說明電流遲滯與界面密切相關(guān)。用溶膠凝膠法和磁控濺射鍍膜法制備了氧化鋅薄膜,分別采用兩步法和乙醚浸泡法制備了 PSCs。研究發(fā)現(xiàn),氧化鋅電子傳輸層具有良好電子傳輸能力,但在退火中更易促進(jìn)活性層退化,導(dǎo)致電池性能快速衰退。
[Abstract]:The optical and electrical properties of three kinds of transparent conductive thin films with interlayer structure based on silver alloy, the heat resistance of transparent conductive thin films with silver and titanium interlayer structure and their applications in polymer solar cells (OSCs) were studied. A perovskite solar cell with PEDOT: PSS as the hole transport layer modified by carbon tetrafluoride plasma was studied, and the technology of inverse PSCs based on zinc oxide electron transport layer was explored. The details are as follows: 1. The optoelectronic properties of transparent conductive thin films (i.e. GZO / Ag / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO / GZO) thin films with interlayer structure of silver aluminum, silver chromium and silver titanium have been studied. In addition, GATG has the characteristics of high temperature resistance. The reason of its high temperature resistance is that titanium atoms form titanium oxide to wrap on the surface of silver particles during silver deposition, which can inhibit the migration and agglomeration of silver atoms and improve the thermal stability of silver alloy layer. The performance of zinc oxide reverse OSCs battery based on GATG was studied. After 20 minutes of ultraviolet irradiation, the original efficiency of the OSCs based on GATG is 59, while that of the OSCs based on ITO (indium tin oxide transparent electrode) is only 23% of the original efficiency. The degradation of the battery is due to the photocatalytic effect of zinc oxide, which accelerates the degradation of the interface between the electronic layer and the active layer, resulting in a significant decrease in the performance of the device, such as open circuit voltage. The photocatalytic effect of ZnO was inhibited by the barrier of ultraviolet light to the active layer by using the GATG electrode, and the UV tolerance of the cell was improved significantly. 3. The photovoltaic properties of perovskite solar cells were studied by using PEDOT: PSS modified by carbon tetrafluoride plasma as the hole transport layer and a two-step method was used to fabricate perovskite solar cells. The results show that the current hysteresis of the cell is serious after the plasma treatment of PEDOT: PSS surface, indicating that the current hysteresis is closely related to the interface. Zinc oxide thin films were prepared by sol-gel method and magnetron sputtering deposition method. PSCs were prepared by two-step method and ether immersion method respectively. It is found that the zinc oxide electron transport layer has good electron transport ability, but it is easier to promote the degradation of the active layer during annealing, which leads to the rapid degradation of the battery performance.
