英文摘要： Based on the mechanism of exciton dissociation and carrier transportation in bulk heterojunction hybrid solar cell, taking advantage of high carrier mobility, transportation pathway, large-area heterojunction interface provided by the structural nature of nanoribbons, and response to visible light attributed to continuous adjustment of band gap of solid solution semiconductor, the project is planned to adopt the novel organic/solid solution inorganic nanoribbon hybrid solar cell, such as P3HT/CIGS, integrated with our research work on catalyst-assisted nanoribbon growth. Controlled catalysis on the growth of CIGS, CIZS nanoribbon, the structural characteristic of bulk heterojunction, the properties of excition dissociation within the heterojunction interface, the properties of carrier transportation in nanoribbon will be focused. The relationship between the nanoribbon and the bulk heterojunction will be demonstrated, and the influence order of nanoribbon on the quantum efficiency of hybrid solar cell will be elucidated. The project will provide theoretic guideline for hybrid solar cell with high quantum efficiency.
