英文摘要	染料敏化TiO2光电化学电池具有较高的能量转换效率, 价格仅为传统单晶硅太阳能电池的1/10, 成为半导体光电化学领域的研究热点［1～4］. 但该类电池内的电解液可流动, 造成电池密封困难, 限制其实用化. 针对这一问题, 采用无机p-型半导体材料［5, 6］和高分子导体等电解液替代物组装固态光电化学电池成为该领域新的研究方向［7～9］. 我们［10］用凝胶网络高分子电解质组装成固态电池, 取得了令人满意的结果.; A novel unsymmetrical cyanine dye (noted as CD) was applied to dye-sensitized nanoporous TiO2 photoelectrochemical cells. The incident photon-to-electron conversion efficiency up to 84.34% was achieved, which is notably high for cells employing pure organic dyes. To circumvent the sealing difficulties present in wet type cells, the solid-state cell was fabricated using poly(ethyleneoxide)(PEO) based gel network polymer electrolyte as charge transfer material between two electrodes. The resulting solid-state cell had an energy conversion efficiency of 0.86%, with open circuit voltage of 0.53 V and short circuit current density of 0.96 mA/cm(2) under 38.1 mW/cm(2) white light illumination. The results show that the gel network polymer electrolyte is appropriate for assembling solid-state photoelectrochemical cells.; 国家自然科学基金; 安徽省自然科学基金; 中国科学院重点实验室基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000170457300008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 14; 7; 1105-1107; 22
