Application of a series of organic dyes for zinc oxide solar cells prepared by the one-step cathode deposition template method was examined. Following informations were obtained :1) Cell performance was improved by introducing long alkyl group at the indole moiety in semisquaric acids. The incident photon-to-current efficiency (IPCE) was improved to 38.0%.2) The addition of deoxycholic acid was effective for oxazines dyes. IPCE and solar-light-to-electricity conversion efficiency (η) were improved to 6.91 and 0.29%, respectively.3) Among 2',4',5',7'-tetrafluoro-, -tetrachloro-, tetrabromo- (eosin Y), and -tetraiodo fluorescein derivatives, the IPCE value was in the following order : I (73%) > Cl (69%), Br (65%) > H (40%) > F (24%).4) Carboxy group was best as an anchor group in squarylium dyes.5) A N-Carboxyethyl indolenium derivative showed the best performance in heptamethinecyanine dyes. An Ethylcyclohexenyl derivative showed the best performance : IPCE (29%), J_<sc>(2.01 mA cm^<-2>). When dimethyl group was changed to dibuthyl group, short-circuit photocurrent density (J_<sc>) value increased to 2.30 mA cm^<-2>.6) 3-(2-Carboxyethyl)-2-[4-(dimethylamino)styryl]benzothiazolium iodide showed the best performance as the sensitizer in flexible zinc oxide solar cell. The IPCE at around 490 nm,.J_<sc>, open-circuit photovoltage (V_<oc>), fill factor (ff), and η were observed to be 54.5 %, 6.22 mA cm^<-2>, 0.53 V, 0.59, and 1.94 %, respectively.

考察了一系列有机染料在一步阴极沉积模板法制备的氧化锌太阳能电池中的应用。结果表明：（1）在半方酸的吲哚基上引入长链烷基可以提高电池性能。入射光电流效率（IPCE）提高到38.0%。IPCE和太阳能光电转换效率（η）分别提高至6.91%和0.29%。3）在2 '，4'，5 '，7'-四氟-、-四氯-、四溴-（曙红Y）和-四碘荧光素衍生物中，IPCE值依次为：4）羧基在方酸染料中作为锚基团的效果最好; 5）N-羧乙基吲哚衍生物在七甲川菁染料中表现出最好的性能。乙基环己烯衍生物表现出最好的性能：IPCE（29%），J_<sc>（2.01 mA cm ~ 2<-2>）。当二甲基基团变为二丁基基团时，短路光电流密度（J_<sc>）值增加到2.30 mA cm ~（<-2>-1）。6）3-（2-羧乙基）-2-[4-（二甲氨基）苯乙烯基]苯并噻唑碘化物作为柔性氧化锌太阳能电池的敏化剂表现出最佳的性能。在约490 nm处观察到IPCE、J_<sc>、开路光电压（V_<oc>）、填充因子（ff）和η分别为54.5%、6.22 mA cm-3<-2>、0.53 V、0.59和1.94%。
