Carbon materials are the most commonly used electrode materials for supercapacitors and the researches of carbon materials are significant for developing supercapacitors. Herein, this article presents the energy storage mechanisms of supercapacitors and the commonly used carbon electrode materials.
At present, research on carbon fiber electrode materials for supercapacitors is very active. Carbon fibers can be activated by concentrated HNO 3 and KOH to enhance their specific surface area and surface wettability, thereby enhancing their electrochemical energy storage performance [8, 9].
As a type of carbon materials, OLCs can be used as electrode materials for supercapacitors. Table 1 summarized the electrochemical performance of different carbon materials. The exohedral structure of OLC with non-porous inside the particles allows electrolyte ions to enter the material easily .
Application of Porous Carbons as Supercapacitor Electrodes Some methods for synthesis of porous carbons have been described previously, and porous carbons will obtain further applications. This is because one of the ultimate goals of supercapacitor research is to achieve high charge-storage capacity at ultra-high scan rates or current densities.
According to the Ministry of Energy Infrastructures and Natural Resources of Armenia, Armenia has an average of about 1720 kilowatt hour (kWh) solar energy flow per square meter of horizontal surface annually and has a potential of 1000 MW power production.
The reason for this is that average solar radiation in Armenia is almost 1700 kWh/m 2 annually. One of the well-known utilization examples is the American University of Armenia (AUA) which uses it not only for electricity generation, but also for water heating. The Government of Armenia is promoting utilization of solar energy.
Solar power potential in Armenia is 8 GW according to the Eurasian Development Bank. The reason for this is that average solar radiation in Armenia is almost 1700 kWh/m 2 annually.
The biggest solar water-heater in Armenia is located at Diana hotel in Goris, which has 1900 vacuum tubes that provide hot water for a swimming pool with 180 cubic meter volume, and for 40 hotel rooms.
In 2017, Solaron became the first Armenian company to begin mass production of photovoltaic solar panels., For this purpose, we have established long-term partnerships with organizations and research centers in the EU and China. Solaron produces solar panels at its own modern production facilities located in Yerevan.
Vertical solar panels, east to west orientation, with bifacial modules near Donaueschingen, Germany. A bifacial solar cell (BSC) is a photovoltaic solar cell that can produce electrical energy from both front and rear side. In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side.
In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side. Bifacial solar cells and solar panels (devices that consist of multiple solar cells) can improve the electric energy output and modify the temporal power production profile compared with their monofacial counterparts.
By 2020, the ENF Solar directory of solar companies lists 184 producers of bifacial solar panels, and according to the International Technology Roadmap for Photovoltaics, they held a 20% share of the overall PV market and its forecast is that this share will rise to 70% by 2030.
In 2019, the European Union announced plans to assist Armenia towards developing its solar power capacity. The initiative has supported the construction of a power plant with 4,000 solar panels located in Gladzor. Solar power potential in Armenia is 8 GW according to the Eurasian Development Bank.

Consumers are allowed to install solar panels with total power of up to 150 kW, and may sell any surplus to electricity distribution company Electric Networks of Armenia (ENA). In Armenia, solar thermal collectors, or water-heaters, are produced in standard sizes (1.38-4.12 square meters).
