Paper Abstract

Non-ion additive hole-transporting material (HTM) of hydrophobic oligothiophene derivative named DR3TBDTT and triphenylamine derivative of N,N′-di(3-methylphenyl)-N,N-diphenyl-4,4-diaminobiphenyl (TPD) were used for the organic-inorganic hybrid perovskite solar cells. The power conversion efficiency (PCE) was comparable to the device using Li-TFSI doped spiro-MeOTAD. Moreover, the PCE decreases by only 10% after approximately 1000 h without encapsulation, which suggests an alternative method to improve the stability of perovskite solar cells[1-3 ]. Figure 1.
