The block copolymers (BCPs) can be quite interesting polymeric materials due to the covalent linkage among different blocks with different comonomers, which prevents microscopic phase separation. However, depending on the incompatibility of different constituent blocks, BCPs may spontaneously self-assemble to form various nanoscale morphologies. Some morphologies give the contiguous conductive pathway that may facilitate the diffusion of ionic species. Polymer gel electrolytes reduce the content of the volatile organic solvents and give flexibility, mechanical and long-term stability to the devices. We have studied PEG-based different triblock copolymers for making gel electrolytes and fabricating quasi-solid-state dye-sensitized solar cells (QSS-DSSCs). The QSS devices give excellent power conversion efficiency and durability under ambient conditions, which can be promising as endless green energy sources for low energy consumed electronics, sensors, and autonomous IoT devices. |
