“…To expedite the transition of this unique type of solar cell from the laboratory to commercial markets, it may be necessary to develop metal-free electrocatalytic materials for the electrode [23]. Accordingly, there have been several metal-free electrocatalysts reported in the literature, such as carbon materials [24,25] and conducting polymers [26,27].…”

A paper-based electrode using a graphene dot/PEDOT:PSS composite for flexible solar cells, Nano Energy, http://dx. AbstractWe have synthesized a metal-free composite ink that contains graphene dots (GDs) and poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) that can be used on paper to serve as the counter electrode in a flexible dye-sensitized solar cell (DSSC). This paper-based GD/PEDOT:PSS electrode is low-cost, light-weight, flexible, environmentally friendly, and easy to cut and process for device fabrication. We determined the GD/PEDOT:PSS composite effectively fills the dense micro-pores in the paper substrate, which leads to improved carrier transport in the electrode and a 3-fold enhanced cell efficiency as compared to the paper electrode made with sputtered Pt. Moreover, the DSSC with the paper electrode featuring the GD/PEDOT:PSS composite did not fail in photovoltaic tests even after bending the electrode 150 times, whereas the device made with the Pt-based paper electrode decreased in efficiency by 45% after such manipulation. These exceptional properties make the metal-free GD/PEDOT:PSS composite ink a promising electrode material for a wide variety of flexible electronic applications.

“…The other is to engineer the structure of the electrocatalyst for I 3 − reduction with regard to the charge transfer route and the surface area. To replace a traditional platinum (Pt) electrocatalyst, where Pt is a rare and expensive element, several types of materials, such as carbon materials [5,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], conductive polymers [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48], and transition metal compounds [37,45, have been extensively explored to elevate the cell efficiency (η) and decrease the cost of the CEs.…”

“…Conductive polymers have attracted much attention as DSSC CEs owing to their excellent conductivity, good adhesion to the substrate, easy fabrication, light-weight, and good accessibility in terms of roll-to-roll processing. Common conductive polymers include poly(3,4-ethylenedioxythiophene) (PEDOT) [30,35,36,[40][41][42][43], poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) [30,43,48], poly(hydroxymethyl 3,4-ethylenedioxythiophene) (PEDOT-MeOH) [46], poly(3,4-propylenedioxythiophene) (PProDOT) [85,86] [48], polyaniline (PANI) [34], and polypyrrole (PPy) [31,38,39,44,48], and their molecular structures are shown in Figure 6. However, conductive polymers often showed a flat or a mesoporous structure, meaning their lacks of the directional electron transfer pathways.…”

In recent decades, plenty of nanomaterials have been investigated as electrocatalysts for the replacement of the expensive platinum (Pt) counter electrode in dyesensitized solar cells (DSSCs). The key function of the electrocatalyst is to reduce tri-iodide ions to iodide ions at the electrolyte/counter electrode interface. The performance of the electrocatalyst is usually determined by two key factors, i.e., the intrinsic heterogeneous rate constant and the effective electrocatalytic surface area of the electrocatalyst. The intrinsic heterogeneous rate constant of the electrocatalyst varies by different types of materials, which can be roughly divided into five groups: non-Pt metals, carbons, conducting polymers, transition metal compounds, and their composites. The effective electrocatalytic surface area is determined by the nanostructure of the electrocatalyst. In this chapter, the nanostructural design and engineering on different types of Pt-free electrocatalysts will be systematically introduced. Also, the relationship between various nanostructures of electrocatalysts and the pertinent physical/electrochemical properties will be discussed.

A two‐step approach is employed for quick and controllable electropolymerization of poly(3,4‐ethylenedioxythiophene) (PEDOT)/polypyrrole (PPy) hollow micro‐/nanohorns on fluorinated tin oxide (FTO) glass substrates as counter electrodes (CEs) for Pt‐free dye‐sensitized solar cells (DSCs). PPy films with hollow micro‐/nanohorn arrays are grown on FTO glasses by a modified pulse potentiostatic method in the first step. Then PEDOT is potentiostatically polymerized onto them as the CEs. Owing to the relatively high catalytic activity of PEDOT and the high specific surface area of hollow micro‐/nanohorn PPy (hPPy), the compound film shows electrocatalytic activity for I3− reduction similar to that of Pt. Therefore, DSCs assembled with this CE exhibit comparable power conversion efficiency (7.08 %) to DSCs with Pt CEs (6.88 %). The PEDOT/PPy film with hollow micro‐/nanohorn arrays can be considered to be a promising alternative CE material for Pt‐free DSCs.
