Now, this app is published as an open-source tool on nanoHUB.org, and you can cite it as well. Have a look https://nanohub.org/tools/jscfromeqeExternal Quantum Efficiency (EQE) is defined as the ratio of number of charge carriers collected at the electrode to the number of photons incident on the solar cell. Low EQE can be attributed to several optical and electrical ...
On December 15 2020, India's Prime Minister Narendra Modi, laid the foundation stone of world's largest Renewable Energy Park in Kutch region of Western Gujarat that is set to produce 30 gigawatts of electricity. This Hybrid Solar-Wind mega-park will build along Indo-Pak border and will spread over 72,600 hectares which is equivalent to the total area ...
Utility companies are doing a great job but one must understand that anticipating the load demand is a critical task. Complexity comes in with the increasing production of electricity from solar energy. Curve shown below represents the load demand curve of electricity in California on 31 March 2012. The blue line in the curve represents the actual load demand in California on ...
These are essentially thin film solar cells. So, thin film of CIGS is used as primary absorber. These are essentially called chalcopyrite based solar cells. CuInSe2 ( Copper Indium Selenide ), CuInS2 ( Copper Indium Sulphide ) and CuGaSe2 ( Copper Gallium Selenide ) with band gap of 1 eV, 1.5 eV and 1.7 eV are the major chalcopyrite compounds that are being used for solar cell ...
In 1972, first CdTe/CdS solar cell was reported. It is a type of photovoltaic that uses Cadmium Telluride (CdTe) and Cadmium Sulphide (CdS) thin film for light absorption and charge extraction for generating electricity using the photovoltaic effect. Two major companies that are manufacturing CdTe solar cells are "Antec" in Germany and "First Solar" in US. ...
In the early stage of technology, amorphous silicon was found to be an interesting material because with doping it can be made P-type or N-type and provided an opportunity for the formation of junction and leading to the formation of solar cells. But after introducing sunlight radiation on solar cell, efficiency decreases and this effect is called Staebler Wronski effect. ...
Gallium Arsenide (GaAs) is a compound of two basic elements; Gallium and Arsenic. It is III-V direct bandgap semiconductor with 1.41 eV band gap, so relatively it can absorb (AM 1.5G spectrum) light more efficiently. This band gap can be varied by Aluminium (Al) or Indium (In) like AlGaAs or InGaAs. First GaAs solar cell was used in space application for Venera 3 mission ...
Solar radiation that earth receives varies inversely with the square of the distance between the sun and earth. Due to continuous motion of the earth in the orbit, radiation coming on earth also varies. Extra-Terrestrial Solar Radiation It is solar radiation just outside the earth’s atmosphere. The figure shown below represents extra-terrestrial solar irradiation. Two ...
Both Solar Energy and Biomass Energy have their individual strengths and weaknesses. Solar energy requires very less maintenance but is limited only for 5-6 hours per day on an average. Biomass energy has an advantage of dispatch ability but biomass prices vary on a wide scale every year. Solar PV-Biomass Hybrid power plant which will enhance the potential of the plant ...
Sunlight takes 8 minutes 20 seconds to reach earth's surface and it is almost 3078 times the energy that we need to sustain. So, our SUN is seen as most abundant renewable energy source. Average global power demand is considered to be 16 TW. Surface power density is a tool which helps us evaluate land requirement for each renewable ...
Softbank CEO, Masayoshi Son Masayoshi Son, is a Japanese businessmen and also the CEO of SoftBank. Son was named world's 45th most powerful person by Forbes Magazine's "List of world's most powerful people 2013". Soudi Crown Prince Mohammad bin Salman Mohammad bin Salman is the crown prince of Saudi Arabia which is the second most important position in the country. ...
Characteristics of Solar Panels Open circuit voltage Voc can be defined as maximum output voltage at zero output current which means whole current flows through the diode (R is infinite). Short circuit current Isc can be defined as maximum output current at zero output voltage which means whole current flows through the load (R is zero). As we can see in figure 1,2 and ...
ICICI Lombard General Insurance made an announcement today that solar park developers can now be covered under the insurance scheme and stated " The standalone insurance product gives comfort to lenders and investors and is a perfect solution to support project finance. The product will be distributed through the company’s branches and affiliated agencies. " Alok ...
Target of 100 GW Solar energy by 2022 is set up by Government of India, motivating Indian solar PV panel manufacturers but but cheaper chinese solar modules have created a burden on these companies and have risked the employment of thousand of workers. Due to this pressure continuity on Indian manufacturers we may see increase in bad loans next year ...
Occupational Safety and Health Administration (OSHA) is an agency for safety and health legislation and have specified certain mandatory measures for ensuring safety at work place. OSHA is an act passed by United States in 1970. Many countries including India follows safety measures provided by OSHA. Guidelines of OSHA are divided into four categories : 1) Eye and face ...
What is Net Metering ?? Net Metering is an agreement signed by the system owner and utility which allows the owner to buy or sell the energy from utility using Net Meter which tracks energy exchange. An Example During early morning or evening hours when there is no sun, energy required to fulfill the load is taken from the utility grid and net-meter ...
For the past few years, much research has been conducted regarding standalone and grid-connected Renewable Energy (RE) sources all over the world. The HOMER tool has been used to analyze a hybrid electric supply system (hydro/PV/wind/ biomass) and to find the optimum sizing of components for a diesel-based RE system. The name HOMER is an abbreviation of “Hybrid Optimization ...
Government announce various schemes to provide continuous power supply to rural India. Still, hundreds of villages use chimney lamps. ‘Electrified’ villages still waiting for power. In many villages, electricity poles have been installed, but lines have not been laid. In order to improve energy security in such places we need “DC Solar Micro Grid” for providing free electricity ...
Before understanding Tilt Angle, we should get familiar with Latitude and Longitude. Latitude and Longitude are imaginary lines that are drawn on maps for locating different places on earth. Latitude is the distance toward north or south of the equator and longitude is the distance toward east or west of prime meridian. Both equator and prime meridian can be seen in the ...
