| 1 | Dopant-free hole transporting materials with supramolecular interactions and reverse diffusion for efficient and modular p-i-n perovskite solar cells显示文摘The rational design of dopant-free organic hole-transporting layer(HTL) materials is still a challenge for realizing high-efficient and stable p-i-n planar perovskite solar cells(pero-SCs). Here, we synthesized two π-conjugated small-molecule HTL materials through tailoring the backbone and conjugated side chain to carefully control molecular conformation. The resultant BDT-TPAs Th containing a planar fused benzo[1,2-b:4,5-b′]dithiophene(BDT) core and a conjugated thiophene side chain showed the planar conformation. X-ray crystallography showed a favorable stacking model in solid states under the parallel-displaced π-πand additional S-π weak-bond supramolecular interactions, thus achieving an obviously increased hole mobility without dopants.As an HTL material in p-i-n planar pero-SCs, the marginal solubility of BDT-TPA-s Th enabled inverse diffusion into the perovskite precursor solution for assisting the subsequent perovskite film growth and passivating the uncoordinated Pb2+ ion defects. As a result, the planar p-i-n pero-SCs exhibited a champion power conversion efficiency(PCE) of 20.5% and enhanced moisture stability. Importantly, the BDT-TPA-s Th HTL material also showed weak thickness-photovoltaic dependence, and the pero-SCs with blade-coated BDT-TPA-s Th as a HTL achieved a 15.30% PCE for the 1-cm2 modularized device. This HTL material design strategy is expected to pave the way toward high-performance, dopant-free and printing large-area planar p-i-n pero-SCs. | Rongming Xue Moyao Zhang Deying Luo Weijie Chen Rui Zhu Yang(Michael)Yang Yaowen Li Yongfang Li | 2020 | Science China Chemistry2020，63，7： | 4 |

| 3 | 高效CsPbI2Br钙钛矿太阳电池晶体生长的精确控制显示文摘文章简介全无机钙钛矿太阳能电池(pero-SCs)因其良好的热稳定性而备受关注,但其较低的功率转换效率(PCE)和水分不稳定性阻碍了其应用。课题组在研究中采用梯度热退火的方法控制α-CsPbI_2Br晶体的生长,然后使用绿色抗溶剂异丙醇进一步优化α-CsPbI_2Br薄膜的形貌。 | Weijie Chen Haiyang Chen Guiying Xu Rongming Xue Shuhui Wang 李耀文 李永舫 | 2020 | 科学新闻2020，，2： | 0 |
