Role of Carbon as Counter Electrode in Dye-sensitized Solar Cells

1. Role of Carbon as Counter Electrode in Dye-sensitized Solar Cells The researchers prefer to use dye-sensitized solar cells more than p-n junction-based solar cells in recent days. The dye-sensitized solar cells include four components: Counter Electrode(CE), photo anode, electrolyte, and sensitizer. Dye-sensitized solar cells (DSSCs) stands are superior to commercial silicon-based photovoltaic devices for their characteristic features such as low fabrication cost, environmentally friendliness, flexibility, semi-transparency, easy assembling, etc. CE In Dye-sensitized Solar Cells The counter electrodes have an important role to play in asserting the electrons across the outer circuit of the dye-sensitized solar cells. This circuit accelerates the reduction reaction of the I3–/I– redox electrolyte. The pt-coated FTO is a promising and common Counter Electrode due to its high electrical conductivity and electrocatalytic activity towards the reduction of redox species and corrosion resistance to iodide/triiodide electrolyte etc.

2. Carbon As Counter Electrode Generally, researchers used deposited platinum on the conductive glass as a counter electrode. Platinum is an earth metal that is rare and takes up the major cost of DSSCs fabrication, and it also reacts with the redox electrolyte which affects the stability of the cell. In recent years, researchers are using one-dimensional carbon-wrapped VO2(M) nanofiber as a counter electrode for dye-sensitized solar cells (DSSCs). The sol-gel-based electrospinning and post-carbonization techniques are simple and versatile and synthesize the uniform short-length nanofiber. The carbon component as a Counter Electrode has high chemical stability and low-cost consumption. The use of Carbon electrodes in dye-sensitized solar cells demonstrates superior power conversion efficiency. This superior performance was a motivation to form a dye-sensitized solar module that consists of six series-connected dye-sensitized solar cells. The series is arranged in a bifacial manner toward the application of building-integrated photovoltaics. The dye-sensitized solar module forms a high conversion efficiency that is driven to fabricate a photo capacitor.

3. The dye-sensitized solar module generates electrical power which is responsible for charging the supercapacitor. The working light which emits the diode appears with the discharge of the supercapacitor. Conclusion To make the dye-sensitized solar cells practically more efficient the researchers use Carbon Electrode in the system. This electrode is highly appreciated for its efficacy and less revenue consumption features. For more information, you may go through the website Dekresearch.com
