Effect of Mechanical Properties of Active Layer on the Performance of Single-component and Bi-component Polymer Solar Cells |
초록 |
Currently, high-efficient polymer solar cells (PSCs) are made of bulk-heterojunction (BHJ)-type blends of conjugated donor and acceptor, and the BHJ system has a morphological issue due to the random arrangement of components. Therefore, single-component polymer system was introduced as an effective solution. As phase separation and mechanically fragile properties of BHJs lead to loss of performance of PSCs during subsequent operation, D/A interfaces must be modified to improve morphological stability against phase separation and mechanical failure. In this study, mechanical properties of active layer for single- and bi-component polymer solar cells were precisely investigated and enhancement of mechanical durability without loss of the electronic properties was successfully demonstrated. As a result, single-component active layer which exhibited higher device performance than its counterpart showed much enhanced mechanical stabilities and reproducibility of internal phase morphology. |
