2、vskite ABX3 tetragonallattice as the (PbI6) octahedra formed infinite chains along the b axis while the chains were separated along the c axis. Instead of red shifting the band gap, a 2.2 V band gap resulted.1-2Also, the propylammonium lead(II) iodide (PAPbI3) formed a faharing lead octahedral struc

3、ture.2Glass-ITO/PEDOT:PSS/ (MAPbI3)1_x(PEI)2PbI4x(x = 2%) /PCBM/LiF/Ag15.2%在 PbI2 中加入 PEI 做前驱体，然后与 MAI 反应，发现少量 PEI 在 MAPbI3 可以调节形貌和增加稳定性 3两步旋涂法Glass-ITO/PEDOT:PSS/ (PEI)2(MA)6Pb7I22/PCBM/LiF/Ag10.08%一步快速法(PEI)2(MA)n-1PbnI3n+1 先在 GBL 结晶再溶于 DMF，小电池效率 10%，大电池效率 8.7%，抗湿度，有前景 4Glass-FTO/c- TiO2/MAPbI3/sp

4、iro/Au17.13%两步旋涂法在 MAI 中加入 CH6N3X (GAX)，电池效率从 16%提高到 17%，GA 并没有进入晶格，只是起添加剂的作用；另外，滞后现象提高，而且没有写清楚 MA 的浓度是固定在 50mg/ml，还是总的 GA+MA固定，也没写清楚是加 GAI 还是加 GACl5Glass-FTO/c-TiO2/ m- TiO2/(C6H9C2H4NH3)2PbI4/spiro/Au(C6H9C2H4NH3)2PbI4 ，其实做出了电池1mA/cm2，0.5V，主要表征光电探测器的性能 60.3%一步法Glass-FTO/c-TiO2/ m-TiO2/ Cs3Bi2I9/sp

5、iro/Ag1.09%一步备了 MA3Bi2I9 和 Cs3Bi2I9，加 Cl 的情况应该是掺进去了加大了带隙没有提高效率，带隙还是 2.1eV 还是太大了，而且形貌也不是太好，最后在 Cs3Bi2I9 电池上做出了 1%的效率 7一步法Glass-FTO/c- TiO2/(PEA)2(MA)2Pb3I10/spiro/Auayered (PEA)2(MA)2Pb3I10resistant8 PEA=C6H5(CH2)2NH3+4.73 %moisture4.73%一步Glass-FTO/c-TiO2/m-TiO2/ (BA)2(CH3NH3)n-1PbnI3n+1/spiro/Au4.03

7、I+FAI 溶液，(IC2H4NH3)2(MA)x(n1)(FA)y(n1)PbnI3n+1 效率 9.03%，但是具体钙钛矿什么成分，已经 MAPbI3 是否形成从而有两层结构等等，都是问题 10Glass-FTO/c-TiO2/ m-TiO2/P1: (p-F-C6H5C2H4-NH3)2-CuBr4, P2:0.63一步法P2/spiro/Ag(CH3(CH2)3NH3)2-CuBr4能电池，效率0.5%,0.63%11%Glass-FTO/c-TiO2/ m-TiO2/MA2CuCl2Br2 /spiro/Ag一步法(CH3NH3)2CuClxBr4x 系列 120.017%Glass
