摘 要: 全钙钛矿叠层太阳能电池(all perovskite tandem solar cell,AP-TSC)拥有巨大的潜力可突破单结Shockley-Queisser限制,但高质量空穴传输层(hole transport layer,HTL)和电子传输层(electron transport layer,ETL)的缺失阻碍了叠层电池的发展。本文利用TCAD Atlas软件对AP-TSC的四种载流子传输层进行优化设计,即顶部HTL、顶部ETL、底部HTL和底部ETL. 结果表明,在聚(3,4-乙烯二氧噻吩)-聚苯乙烯磺酸(poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate),PEDOT:PSS)、2,2',7,7'-四[N,N-二(4-甲氧基苯基)氨基]-9,9'-螺二芴(2,2',7,7'-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene,Spiro-OMETAD)、CuI、CuO、NiO和CuSCN中,NiO是最适合的顶部HTL和底部HTL材料。在C60、SnO2、TiO2、ZnO、[6,6]-苯基-C61-丁酸异甲酯((6,6)-phenyl-C61 butyrie acid methyl ester,PCBM)和CdS中,SnO2和ZnO分别是最合适的顶部ETL和底部ETL材料。此外,钙钛矿厚度对电池效率的影响研究得出,无电流限制下FA0.8Cs0.2Pb(I0.7Br0.3)3和MAPb0.5Sn0.5I3的厚度拟合方程为y=0.75x35. 通过材料设计和钙钛矿厚度优化,在异质结界面复合速率为1 000 cm/s时,AP-TSC依然实现了32%的效率。

Abstract: All perovskite tandem solar cells (AP-TSCs) have immense potential to break through the single-junction Shockley-Queisser limit, but the lack of high-quality hole transport layer (HTL) and electron transport layer (ETL) hinders the development of tandem cells. In this paper, four carrier transport layers of the AP-TSCs were optimized by TCAD Atlas software, i.e. top HTL, top ETL, bottom HTL and bottom ETL. The results indicated, among poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS), 2,2',7,7'-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene (Spiro-OMETAD), CuI, CuO, NiO and CuSCN, NiO was the most appropriate material of top HTL and bottom HTL. Among C60, SnO2, TiO2, ZnO, (6,6)-phenyl-C61 butyrie acid methyl ester (PCBM) and CdS, SnO2 and ZnO were the most suitable materials of top ETL and bottom ETL, respectively. In addition, the influence of perovskite thickness on the efficiency of the tandem cells was studied, and the thickness fitting equation y=0.75x35 of FA0.8Cs0.2Pb(I0.7Br0.3)3 and MAPb0.5Sn0.5I3 was obtained without current limitation. By optimizing the transport layer material and the thickness of the perovskite, the efficiency of the AP-TSCs achieved 32% when recombination rate at heterojunction interface was 1 000 cm/s.
