| Research Abstract |
In this research, we aim to analysis the degradation mechanism for inverted polymer solar cells and to fabricate the high durable polymer solar cell in air.
The relationship between the morphology of a P3HT : PCBM photoactive layer and performance of its bulk-heterojunction polymer solar cells was investigated. AC impedance spectroscopy, carrier mobility measurements and AFM observation of the photoactive layer surface revealed that the degradation of the polymer solar cell was caused by the initial well-connected network within the P3HT : PCBM layer changing to a morphology. Following this result, we achieved to fabricate the high durable polymer solar cell which almost maintains the maximum PCE under continuous light irradiation for 100 h in air. In addition, the performance of the sealed cells was almost constant in open field test for 1 year under continuous light irradiation.
