Experimental report on solar cells

solar photovoltaic (PV) cell converts sunlight to electricity. In the photoelectric effect at a metal surface, electrons are freed once the energy exceeds the bond energy. In a solar cell, an asymmetry is established by contacting two semiconductors of opposite polarity which drives electrons that are freed by the incident light in.

Can physics students plot the I-V characteristics of a solar cell?

The purpose of this article is to describe a very simple experiment that allows college students in introductory physics courses to plot the I-V characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor (E) and light conversion efficiency.

Should students learn about solar cells?

Solar cells often capture the public’s attention and are a source of fascination to students (Hamakawa 1987, Zweibel 1990). We have found it profitable to tap this interest in solar cells by introducing students at an early stage of their undergraduate curriculum to the rudiments of photovoltaic devices.

Are solar cells the ultimate energy source of the future?

Cost and Future Prospects In general, solar cells appear to be the ultimate energy source of the future. They are simple to operate, simple to maintain, mechanically uncomplicated, reliable, safe (with no harmful by-products), and operate with a minimum lifetime of 20 years at a reasonable energy conversion efficiency. But they axe also expensive.

How does spectral nature affect the design of solar cells?

Therefore, the spectral nature of sunlight is a fundamental aspect affecting the design of efficient solar cells. The solar cell is the photovoltaic’s building block. Usually, it is made of a 100 cm2 silicon wafer whose surface has been treated to maximize light absorption and thus appears dark blue or black.

What is solar cell efficiency?

It collects those positive and negative charges on two different terminals so they can be used to do work in an electric circuit. Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight.

What is a solar cell?

r cell is a semi conductor device, whi h converts the solar energy into electrical energy. It is also called a photovolt ic cell. A solar panel consists of numbers of solar cells connected in series or parallel. The number of solar cell connected in a series generates
