“…The T 2 /T -redox couple is a member of larger family of similar organosulfur compounds based on disulphide, polysulfides, thiourea, cysteine etc. which were also tested in DSCs [20,22,[24][25][26][27]. Since the redox potential of T 2 /T -is close to that of I 3 -/I -, there is almost no improvement in V OC and Φ sol as compared to the reference I-mediated DSCs.…”

“…However, the I 3 − /I − redox electrolyte has several critical disadvantages such as the corrosion of copper/silver lines, visible light absorption and the complicated redox chemistry to cause great energy loss. [9][10][11] To overcome these limitations, new redox couples including TEMPO/TEM-PO ＋ , [12] TMTU/TMFDS 2 ＋ , [13] thiolate/disulfide, [14] ferrocene(0/ ＋ ), [15] copper(I/II), [16][17][18] and cobalt-(II/III) [19][20][21][22][23][24] were explored. Recently, major progress has been achieved through the development of DSSCs based on electrolyte containing cobalt(II/III) redox couple, which afford record efficency of up to 12.3%.…”

The nanocomposites of cobalt selenide and nickel selenide (Co 0.85 Se/Ni 0.85 Se) were successfully fabricated on FTO glass by a facile co-electrodeposition method at ambient temperature. Nanocomposite films were used as electrocatalysts in dye-sensitized solar cell counter electrodes for regeneration of both iodide/triiodide and cobalt(II/III) redox couples. Co 0.85 Se/Ni 0.85 Se were mainly composed of nanoflakes and nanoparticles. It is noted that such nanostructure generated by nanoparticles embedded with 2D nanoflakes led to high active sites and was accessible to cobalt(II/III) electrolyte, delivering better catalytic activity for the reduction of larger volume cobalt(II/III). As a result, for cobalt(II/III) electrolyte, the Co 0.85 Se/Ni 0.85 Se based dye-sensitized solar cell performed significantly improved efficiency than that of Pt and Co 0.85 Se. Meanwhile, the Co 0.85 Se/Ni 0.85 Se based dye-sensitized solar cell held comparable energy conversion efficiency to that of Pt and Co 0.85 Se for iodide/triiodide electrolyte.

Controlled radical polymerization (CRP) and dye-sensitized solar cells (DSSCs) are two fields of research that at an initial glance appear to have little in common. However, despite their obvious differences, both in application and in scientific nature, a closer look reveals a striking similarity between many of the compounds widely used as control agents in radical polymerization and as redox couples in dye-sensitized solar cells. Herein, we review the various redox active compounds used and examine the characteristics that give them the ability to perform this dual function. In addition we explore the advances in the understanding of the structural features that enhance their activity in both CRP and DSSCs. It is hoped that such a comparison will be conducive to improving process performance in both fields.
