A New Type of Electrolyte with a Light-Trapping Scheme for High-Efficiency Quasi-Solid-State DSSC

5526 www.advmat.de www.MaterialsV C O M M U N IC A TI O N A New Type of Electrolyte with a Light-Trapping Scheme for High-Effi ciency Quasi-Solid-State Dye-Sensitized Solar Cells By Meng Wang, Xu Pan,* Xiaqin Fang, Lei Guo, Weiqing Liu, Changneng Zhang, Yang Huang, Linhua Hu, and Songyuan Dai* Dye-sensitized solar cells (DSSCs) are attracting both aca- demic and industrial interest owing to their high-effi ciency and potential low-cost. [ 1 ] The electrolyte, containing the I ? /I 3 ? redox couple, is the one of the most-important com- ponents of a DSSC, and directly infl uences their perform- ance and stability. [ 2,3 ] Generally, the role of the electrolyte in a DSSC is to fi nish the charge cycle, including the transport of the I ? /I 3 ? redox couple, [ 4 ] the regeneration of oxidized dye at the dyed TiO 2 /electrolyte interface and the reduction of I 3 ? at the counter electrode. [ 5 ] However, I 3 ? in the electro- lyte will absorb visible light, [ 6 ] which results in energy loss. Furthermore, due to the inhomogeneous dye distribution, [ 7 ] a certain part of the incident light transmits through the photoanode, which decreases the light-harvesting effi ciency. As we know, although relatively large particles have already been used in DSSCs to help increase the light-harvesting effi - ciency, still part of the incident light will transmit through the photoanode. Moreover. an excess of large particles will not only lower the light-harvesting effi ciency over the whole range of visible wavelengths owing to enhanced light refl ection at the conducting glass/TiO 2 interface, but also decrease the electron-transfer yield. [ 8 ] As reported previously, [ 9 ] light trapping has become a standard technique to increase the light absorption of incident light in the active layers of hydrogenated amorphous-silicon- based solar cells, based on the use of textured substrates and highly refl ective back contacts.
