Decoupled interface dipole moments and energy level alignment in organic solar cells and hybrid perovskite solar cells |
| 초록 |
The dipole moment of interfacial materials has played the key role in efficient charge extraction in organic and hybrid perovskite solar cell, but the mechanisms of the interaction at the interface and of the resulting energy level alignment have not been well established. The mechanisms of decoupled interface dipole moments are evaluated by using spontaneously and nonspontaneously aligned dipolar interface molecules, thereby the energy-level adjustment of the dipolar interface layer in the devices are elucidated. Therefore, we systematically tailored the interface dipole moment and the energy level alignment of interface materials to remove the energy offset at the interface and achieve the efficient organic solar cells and hybrid perovskite solar cells with diverse interface materials and photoactive materials. |
