This project will take three years to finish. This project includes two innovative directions, sandwiched structure hybrid thin film solar cells and novel innovative polymer-nanoparticle hybrid materials. These two directions integrates the expertise in organic/inorganic devices (Task I), interface engineering (Task II), packaging technique (Task III), novel hybrid materials for photovoltaics (Task IV), structure and morphology of novel hybrid materials (Task V), physical phenomena of photovoltaics (Task VI), Building-integrated photovoltaic (Task VII). The key issue is that these cells utilize inorganic materials as the two outer layers with the organic material between the two inorganic layers. This configuration protects the light absorbing organic layer in the middle and produces a far more stable organic layer in the thin film solar cell. Moreover, the inorganic layers with higher carrier mobility can also serve as electron/hole transport and blocking layers, which can efficiently suppress the leakage current and enhance the cell performance. More importantly, the inorganic layers can be developed in air from a solution-processed approach which has the advantages of low-cost and large-area applications. Via photoemission spectroscopies, the characteristics of organic solar cells could be investigated, including the changes of HOMO levels, work function, vacuum levels, and electronic structures as well as the phenomenon of carrier transport and induced interfacial chemical reactions at the interface. These can provide the information of carrier transport process at the interface between an electrode and an organic semiconductor. We will also focus on the development of low-temperature organic/inorganic hybrid encapsulation technology against oxygen and moisture permeation. Employing both theoretical modeling and experimental methodology, we will obtain bandgap matching polymer, nanoparticle, interface modifier and high light harvesting hybrid that can be fabricated into special designed solar cell. We will expect to have solar cell with a power conversion efficiency of 8~10％, price lower than US＄50/m2 or US＄1.0/W. We will demonstrate the feasibility of utilizing hybrid solar cell for building power supply.有機/無機混成三明治結構金屬氧化物光電子能譜介面反應低溫封裝水氧阻絕層混成形貌與結構建築整合型太陽光電Organic-inorganic hybridSandwiched structureMetal oxidesPhotoemission spectroscopyInterfacial chemical reactionLow-temperature encapsulationMoisture and oxygen barrierHybrid material morphology and structureBuilding-integrated photovoltaic有機無機混成薄膜太陽能電池
