The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
One method of converting energy from the sun (solar energy) is to use a solar cell also known as a photovoltaic cell. A solar cell uses the photovoltaic effect to convert solar radiation directly to DC electrical energy.
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
In 1883, Charles Fritts described the first solar cells made from selenium wafers. In 1905, Albert Einstein published his paper on the photoelectric effect. In 1914, the existence of a barrier layer in photovoltaic devices is noted.5 In 1916, Robert Millikan provided experimental proof of the photoelectric effect. In 1954,
Photovoltaic (PV) cells create electricity from sunlight and are one of the true success stories of materials science. Photovoltaic cells have grown from an area of study once viewed with skepticism to a multi-billion dollar market that promises tremendous continued growth.
Solar energy can be part of a mixture of renewable energy sources used to meet the need for electricity. Using photovoltaic cells (also called solar cells), solar energy can be converted into electricity. Solar cells produce direct current (DC) electricity and an inverter can be used to change this to alternating current (AC) electricity.
