What are the characteristics of solar cell material?
The basic characteristics of a solar cell are the short-circuit current (ISC), the open-circuit voltage (VOC), the fill factor (FF) and the solar energy conversion efficiency (η).
Which of the following material is not used in solar cells?
We don’t use PbS as solar cells material because it absorbs all the solar radiations as its top layer which will stop it to reach to depletion zone. Solar cell is also called as a photovoltaic cell. It converts light energy to electrical energy.
What are the characteristics of solar cell Mcq?
Explanation: A p-n junction which generated EMF when solar radiation is incident on it is called a solar cell. The material used for fabrication of solar cell should have a band gap of around 1.5 eV. 2.
What are the materials required for the construction of solar cells Mcq?
Solar Cell MCQ Question 7 Detailed Solution
Solar cells are made of semiconductor materials like silicon, cadmium telluride, and copper indium gallium selenide.
How many types of solar cells are there?
Solar cells can be divided into three broad types, crystalline silicon-based, thin-film solar cells, and a newer development that is a mixture of the other two.
Is germanium used in solar cells?
Germanium serves as the bottom layer of the most efficient existing type of solar cell, but is used primarily on NASA, military and commercial satellites because of the high expense – raw germanium costs about $680 per pound. … Germanium is a semiconductor at the bottom of “multijunction” solar cells.
Which of the following materials is used in solar heat energy storage?
The sensible heat of molten salt is also used for storing solar energy at a high temperature. It is termed molten-salt technology or molten salt energy storage (MSES). Molten salts can be employed as a thermal energy storage method to retain thermal energy.
