英文摘要: Highly ordered organic nano-structured arrays will be grown by using vapor-phase deposition or template growth method and applied in polymer solar cells (PSCs). PSCs with highly ordered organic nano-structured arrays and polymer interpenetrating structure are expected to improve the photo-induced excitation dissociation efficiency as well as improve the carrier transport and collection efficiency. The specific research contains: ① Preparation of high carrier mobility nano-sized organic semiconductor materials. By using interfacial template layer and/or external electric field or magnetic field, etc., to control the molecular orientation and nano-growth direction of the nano-materials, we will prepare highly ordered nano-structured organic arrays with high carrier mobility, which will be applied in photo-active layer, nano-electrode or interfacial modification layer in PSCs. We will also investigate and simulate the growth kinetics of organic nano-structured arrays and optimize the arrays. ② The prepared highly ordered organic nano-structured arrays will be applied in photo-active layer, nano-electrode, or electrode interface in PSCs. We will investigate the effect of molecular orientation and growth direction of nano-materials to PSCs performance. A systematic study for the interpenetrating contact interface bet
