Recently,solution-processable perovskite solar cells(PSCs) have created much excitement with certified PCEs of 22.1%,challenging the long-standing perception that high efficiencies must come at high ***,one major bottleneck for the practical application of PSCs is the expensive HTMs and CE *** this work,we present structure engineering of the PSCs with low-temperature printable carbon and cost-effective HTMs to solve the cost issues facing *** low temperature(≤100 °C) printable carbon paste was developed as counter electrode in TiO/CHNHPbI heterojunction PSCs to substitute the noble metallic materials and avoid the application of expensive HTMs for the first *** impressive PCE of 8.31% and enhanced stability over 800 h was demonstrated [1](Figure 1.b).Then the low temperature printable carbon counter electrode based PSCs was for the first time interfacially engineered with cost-effective,dopant-free Cu Pc nanorods to elevate the interfacial barrier and facilitate charge extraction,a boosted PCE of 16.1% was afforded,being one of the highest efficiencies for carbon CE based PSCs [2](Figure 1.c).Motivated by further reducing the energy consumption in device fabrication,a kind of noble metal-free,vacuum-free PSCs was developed by incorporating a cost-effective,solution-processable HTM TPDI and low temperature printable carbon as counter *** optimized PCE of 15.5% and 13.6% was demonstrated by its doped and pristine form,respectively[3](Figure 1.d).All these results demonstrated important steps forwards to practical application of PSCs,as it paves the way for development of cost-effective,stable and highly efficient PSCs.

In the past few years, the power conversion efficiencies(PCEs) of PSCs have been rapidly boosted from the initial 3.8% in 2009 to over 23%. At present, the most commonly used HTMs are Sprio-OMeTAD and PTAA. However, their synthetic costs are prohibitively high, limiting their large-scale application in future commercialization. Therefore, it is highly appreciated to develop or search for low-cost and highly efficient alternatives to Spiro-OMeTAD and PTAA, aiming at reaching state-of-the-art photovoltaic performance. Based on these concerns, herein, we report two facilely synthesized PDO core building block based HTMs. PDO has a symmetrical nonplanar structure. By substituting its 3-and 7-positions with 4,4’-dimethoxydiphenylamine, and substituting the N-position with anisole or 4,4’-dimethoxytriphenylamine as the peripheral groups afforded HTMs PDO1 and PDO2, respectively. The introduction of two 4,4’-dimethoxydiphenylamine groups on PDO unit are supposed to adjust the energy level and charge carrier mobility, while the N-substitutions are to tune the spatial configuration of HTMs. These two PDO-based HTMs show high hole mobility, high conductivity and suitable highest occupied molecular orbital(HOMO) and lowest unoccupied molecular orbital(LUMO) levels. Through optimization, the PSCs employing PDO2 as HTM show PCEs up to 20.2%, and good stability when aged in ambient condition in the dark for 500 h.

碳基钙钛矿太阳电池(C-PSCs)具有低成本和高稳定性的优势,这归因于碳电极的化学惰性和疏水性.然而,C-PSCs的光伏性能通常低于相应的金属电极器件,其中最重要的原因是钙钛矿层和碳电极之间低的空穴提取效率.这里,我们发展了一种基于碳纳米管/聚三己基噻吩(CNT/P3HT,CP)复合材料的空穴传输材料用于构建C-PSCs.P3HT和CNTs之间的强相互作用力增强了P3HT的结晶度,同时也改善了CNTs的分散性.相比于纯P3HT,CP复合材料中的CNT提供了空穴传输的高速通道,进而有效地降低电荷传输阻抗和改善空穴提取效率.这种CP复合材料被用于组装CsPbI_(2)Br C-PSCs,其光电压由1.233 V提高到1.355 V,能量转换效率也由13.29%提高到15.56%,刷新了碳基全无机钙钛矿太阳电池的记录.
