Solid-state dye-sensitized solar cells currently suffer from issues such as inadequate nanopore filling, low conductivity and crystallization of hole-transport materials infiltrated in the mesoscopic TiO2 scaffolds, leading to low performances. Here we report a record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global using a hole-transport material composed of a blend of [Cu (4,4′,6,6′-tetramethyl-2,2′-bipyridine)2](bis(trifluoromethylsulfonyl)imide)2 and [Cu (4,4′,6,6′-tetramethyl-2,2′-bipyridine)2](bis(trifluoromethylsulfonyl)imide). The amorphous Cu(II/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 μm-thick mesoscopic TiO2 scaffold are crucial for achieving such high efficiency. Using time-resolved laser photolysis, we determine the time constants for electron injection from the photoexcited sensitizers Y123 into the TiO2 and regeneration of the Y123 by Cu(I) to be 25 ps and 3.2 μs, respectively. Our work will foster the development of low-cost solid-state photovoltaic based on transition metal complexes as hole conductors.

“…It has also exhibited strong electrocatalytic behavior toward the redox reaction of the I -/I 3 -electrolyte, as demonstrated via cyclic voltammetry analysis [42][43][44]. As a result, researchers have widely incorporated PEDOT as the counter electrode in DSSCs in addition to using it as a hole transport layer in solid-state photovoltaic devices due to its high work function [45,46]. However, PEDOT is not soluble in most solvents, which makes solution processing problematic.…”

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.

“…Since the only 5-10% of sunlight is in this range, in solar cells based on Cadmium Oxide (CdO) and Rhodium (III) Oxide (Rh 2 O 3 ) nanoparticles, for making them sensitive to visible light, dyes are used as scavenger. In this editorial, the method of manufacturing electrodes which are synthesized by Mercurochrome have been studied and comparing of their efficiency due to their structure and morphology, have been done by Energy Dispersion Analysis (EDS), Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM), Differential Thermal Analysis-Thermal Gravim Analysis (DTA-TGA), Energy-Dispersive X-Ray Spectroscopy (EDX), 1 HNMR, 13 CNMR, UV-Vis, Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR) and FT-Raman spectroscopies and also ESI MS, PM5 and DFT studies. …”
