A simple spiro-type hole transporting material for efficient perovskite solar cells

Energy Environ. Sci. 2015, 8, 1986.

Energy Environ. Sci.

We developed a cost-effective spiro-type 4,4[prime or minute],4[prime or minute][prime or minute],4[prime or minute][prime or minute][prime or minute]\-(2H,2[prime or minute]H,4H,4[prime or minute]H-3,3[prime or minute]-spiro-bi[thieno[3,4-b][1,4]dioxepine]-6,6[prime or minute],8,8[prime or minute]-tetrayl)tetrakis(N,N-bis(4-methoxyphenyl)aniline) hole transporting material (PST1) for perovskite solar cells (PSCs) that works efficiently even without a cobalt dopant. The PST1 is obtained by employing facile synthetic routes and tends to crystallize in the solid state. An X-ray diffraction study of PST1 revealed a unique quasi-spiro molecular configuration and found multiple CH/[small pi] and [small pi]-[small pi] intermolecular contacts. For the first time, the crystal structure of 2,2[prime or minute],7,7[prime or minute]-tetrakis(N,N[prime or minute]-di-p-methoxyphenylamine)-9,9[prime or minute]-spirobifluorene (spiro-OMeTAD) is also studied for comparison. The device based on PST1 exhibited a PCE of 13.44%, and a comparable 12.74% PCE was achieved for its undoped form, which paves the way for developing new low cost hole transporting materials and final industrialization of perovskite solar cells.
