In addition to exploiting light-harvesting materials which are suitable for indoor applications, we will also develop compatible interfacial materials to optimize the associate interfaces in the devices. We eventually will integrate the material, interface, and device engineering to further optimize device’s performance, reproducibility, and operational stability, and anticipate contributing to the future commercialization and integration with the IoT ecosystem. We aim to achieve the following goals in this 3-year proposal: (1)Developing large band gap organic and perovskite light-harvesting materials. For the organic light-harvesting materials, new large band gap polymer donors and non-fullerene acceptors will be developed in order to match the spectra of indoor light; for perovskite materials, the composition will be engineering along with the dimension tailoring to develop large band gap perovskite materials with good stability. (2)Investigating the film quality and properties of large band gap organic and perovskite light-harvesting materials and their associate interface engineering. By using organic compounds to modify the associated interfaces in the device and investigate the charge-transfer states of the photoactive materials and the physics/chemical phenomenon at the relevant interfaces. (3)Integrating the developed photoactive and interfacial materials to develop high-performance solar cell devices for indoor applications. Meanwhile, device’s reproducibility and stability will be optimized to promote the future upscaling and commercial production of indoor solar cell devices.物聯網;室內弱光;寬帶隙光活性材料;介面材料;太陽能電池;Internet of Things;Indoor Application ;Large Band Gap Photoactive Materials;Interfacial Materials ;Solar Cells
