Organic solar cells (OSCs) have been made to explore potential applications due to potential of module with large area and flexible devices. To apply wearable and flexible device, high performance and mechanical strength are very important point. We applied strategy of hybridization to electron transport layers (ETLs) for enhancing performance and flexibility. Generally used ETLs, metal oxide (ex. ZnO, TiOx, SnO2, etc.), have high conductivity and transparency for high performance. However, they usually necessary annealing process in high temperature which is not favorable for flexible device. The robust hybrid ETLs exhibits enhanced conductivity and mechanical strength due to complex structure. As results, OSCs which were fabricated with modified ETLs exhibits high performance both in unit-cells (0.04 cm2) and large area device (over 1 cm2). Furthermore, the devices implemented on flexible substrate are exhibited high mechanical strength. |
