项目标书摘要：本计划的研究主题为：在室温的条件下，以超临界二氧化碳(supercritical CO2,SCCO2)流体制程研制多孔隙金属氧化膜，并探讨其在电子纸(e-paper)显示器及有机太阳能电池上的应用。我们所提出的SCCO2 制程十分独特，它利用二氧化碳在超临界的条件下同时具有液体、气体特性的性质，可以有效渗入有机/无机混成材料的内部，溶解有机材料的部分而形成多孔隙结构的薄膜。这种有效形成多孔隙材料的方法可以在低温下实施大面积、批次样品的制程，因此非常适用於软性电子产品的商业生产；同时由於SCCO2 制程中消耗的制程材料(如二氧化碳及添加剂)少，且可回收再利用，亦具环境保护的特性。本计划为一三年期的计划；主要的工作是以 SCCO2 制程备制多孔隙金属氧化膜，并以电子纸显示器及有机太阳能电池作为应用载具，以证实此方法的可行性与实用性。在计划执行的第一年，我们将利用SCCO2 制程技术对氧化铟锡(ITO)金属氧化膜进行表面改质工程，改质後ITO 薄膜的表面特性与传统氧电浆处理後的品质相似，但在设备上的投资可大幅降低；此外，我们会研发在低温的条件下制作多孔隙氧化鍗锡薄膜(porous ATO)之制程技术，目标是经SCCO2 制程处理後，材料的孔隙度大於 50%、电阻率小於3 Ωcm。在完成第一年的准备工作後，我们在计划执行的第二年将已开发完成之多孔隙ATO 薄膜应用於electro-deposition 电子纸显示元件；这层多孔隙ATO 薄膜可取代传统之多孔隙高温烧结TiO2 厚膜作为元件的金属吸附层，具制程简易、低价、高效能及可应用於高分子基板的优点。在计划执行的最後一年，我们将以SCCO2 制程研制多孔隙 ITO/ITO 双层电极结构，并将此新型电极应用於有机太阳能电池中；多孔隙ITO 特殊电极具散射入射光的功能，可有效增加电池的等效吸收路径，使有机太阳能电池的外在量子效率提高。

Application Abstract: The objective of this project is to fabricate porous metal oxide thin films by supercritical CO2(SCCO2)treatment at low temperature and to investigate their applications in e-paper and organic solar cells.The proposed SCCO2 treatment is unique,because it replies on excellent diffusion capability of both liquid-like and gas-like carbon dioxide into hybrid thin films.Porous structure of the films can be obtained due to dissolving of organic components in the films.This effective method of preparing porous thin films is applicable for commercial flexible electronics since it is a batch process and can be applied on large area samples for mass production.In addition,The SCCO2 process is environmentally friendly because the consumption of chemicals in the process is low and recyclable.This project is scheduled to operate for three years.The primary targets of the project are to fabricate porous metal oxides and test the feasibility of the proposed technique for e-paper and organic solar cells.In the first year of the project,we will use the SCCO2 treatment to improve the surface chemical properties of Indium-Tin Oxide(ITO).After the treatment,the surface energy and work function of the materials are similar to those of the ITO films treated by conventional oxygen plasma.However,the cost of the treatment can be significantly reduced.In addition,porous antimony-doped tin oxides(ATO)are fabricated using the SCCO2 treatment.After process,we believe that the film porosity is larger than 50%,and the film resistivity is less than 3 Ωcm.After the preparation of the first-year project,we will apply the fabricated porous ATO thin film for electro-deposition e-paper devices.This porous thin film can be used to replace conventional TiO2 thick film prepared by high temperature annealing.The merits of the proposed technique are simple,low cost,high efficiency,and applicable for polymer substrates.In the last year of the project,we will fabricate a novel porous ITO/ITO double-layered electrode.This electrode can provide scattering of the incident lights,and therefore the effective absorption length and external quantum efficiency of an organic solar cell is significantly increased.
