“…The PCE of the DSSC with the Ti/Ru bilayer CE was 2.40%, and the increase in efficiency was 1.48 times that of the device with a 100 nm Ru only CE. Using similar methods, Noh and Song prepared many bilayer CEs by RF sputtering techniques, including Al/Ru, 288 Au/Pt, 284 Cu/Pt, 289 etc. The PCE of the device with Al/Ru bilayer CE was 2.36%.…”

“…284 And the PCEs of the DSSCs with only Pt and Cu/Pt bilayer CEs were 4.60% and 5.72%, respectively. 289 Silver (Ag) is a soft, white, lustrous transition metal and it exhibits the highest electrical conductivity, thermal conductivity and reflectivity of any metal. Ag shows high corrosion resistance and stability in pure air and water and is therefore used as a CE material in DSSCs.…”

Dye-sensitized solar cells (DSSCs) are regarded as prospective solar cells for the next generation of photovoltaic technologies and have become research hotspots in the PV field. The counter electrode, as a crucial component of DSSCs, collects electrons from the external circuit and catalyzes the redox reduction in the electrolyte, which has a significant influence on the photovoltaic performance, long-term stability and cost of the devices. Solar cells, dye-sensitized solar cells, as well as the structure, principle, preparation and characterization of counter electrodes are mentioned in the introduction section. The next six sections discuss the counter electrodes based on transparency and flexibility, metals and alloys, carbon materials, conductive polymers, transition metal compounds, and hybrids, respectively. The special features and performance, advantages and disadvantages, preparation, characterization, mechanisms, important events and development histories of various counter electrodes are presented. In the eighth section, the development of counter electrodes is summarized with an outlook. This article panoramically reviews the counter electrodes in DSSCs, which is of great significance for enhancing the development levels of DSSCs and other photoelectrochemical devices.

“…For the counter electrode, studies on increasing the efficiencies by making double layer structures of Cr/Pt, etc. in the place of Pt employed as a catalyst in the past have been reported, 4) while studies have been published on enabling an increase in the efficiencies through expansion of the wavelength band of absorbable light by adding phosphor materials to the dye part. 5) For efficiency improvement studies through engineering of the working electrode part, much investigation is being conducted for addition of new materials capable of increasing specific surface areas and electron mobilities of the working electrode part.…”

We prepared blocking layers by adding 0.0~0.6 wt% nano diamond blends (DBs) to TiO 2 blocking layers to improve the energy conversion efficiencies (ECEs) of dye sensitized solar cells (DSSCs). TEM and micro-Raman spectroscopy were used to characterize the microstructure and phases of DBs, respectively. Optical microscopy and FE-SEM were used to analyze the microstructure of the TiO 2 blocking layer with DBs. UV-VIS-NIR spectroscopy was used to determine the absorbance of the working electrodes. A solar simulator and a potentiostat were used to determine the photovoltaic properties and the impedance of the DSSCs with DBs. From the results of the DBs analysis, we determined a 6.97 nm combination of nano diamonds and graphite. We confirmed that ECE increased from 5.64 to 6.48 % when the added DBs increased from 0.0 to 0.2 wt%. This indicates that the effective surface area and electron mobility increased when DBs were added to the TiO 2 blocking layer. Our results indicate that the ECE of DSSCs can be enhanced by adding an appropriate amount of DBs to the TiO 2 blocking layers.
