Novel DSSCs (Dye Sensitized Solar Cells) have been developed with difunctionalized dyes, which are based on isophthalic acid or 4-tert-butylcalix[4]arene as scaffold and N,N-dialkylaniline as electrondonor connected to thiophene as π-spacer. This heteroaromatic ring has been used because of its thermal stability and adequate charge transfer. The use of 4-tert-butylcalix[4]arene has given rise a considerable increase of the molar extinction coefficient in this difunctionalized dye relative to the individual one, which makes them susceptible to be used in low luminosity condition. All dyes have been completely characterized. The photoelectrochemical properties of the devices prepared with or without co-adsorbate (chenodeoxycholic acid) have been determined. When co-adsorbate is added, solar cells prepared with isophthalic acid and 4-tert-butylcalix[4]arene have power conversion efficiencies of 6.0 and 6.3%, respectively; such devices also display good long-term stability up to 1000 h.

已经开发了具有双官能化染料的新型DSSC（染料敏化太阳能电池），该染料基于间苯二甲酸或4-叔丁基杯[4]芳烃作为骨架，N，N-二烷基苯胺作为电子给体，与噻吩连接作为π-间隔基。该杂芳族环由于其热稳定性和足够的电荷转移而被使用。4叔的使用相对于单个染料，丁基丁基杯[4]芳烃使该双官能化染料的摩尔消光系数显着提高，这使其易于在低发光度条件下使用。所有染料均已完全鉴定。已确定使用或不使用共吸附物（鹅去氧胆酸）制备的器件的光电化学性能。当添加共吸附物时，用间苯二甲酸和4-叔丁基杯[4]芳烃制备的太阳能电池的功率转换效率分别为6.0％和6.3％；此类设备在长达1000小时的情况下也显示出良好的长期稳定性。
