What are solar cells?
Solar cells are the building blocks of solar panels. In one solar panel there are many individual solar cells. Solar cells are sometimes called ‘photovoltaic’ or ‘PV’ cells (from the Greek word ‘photo’ meaning ‘light’, and ‘voltaic’ meaning voltage or electrical current).
What is a photovoltaic (PV) cell?
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.

Is a solar cell a naive physics model?
Although our model of a solar cell is naive, neglecting as it does contri- butions from shunt and series resistance to the equivalent electrical circuit of the cell, it never- theless captures the essential physics and allows undergraduate students to analyse the important characteristics of a silicon solar cell.
Who invented solar cells?
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,

The silicon material is preferred in photovoltaic cells since the atoms are bounded together to form a uniform shape to yield maximum solar power to convert electric energy [9]. Also the silicon material based batteries are preferred rather than graphite, since the use of silicon reduces the size and weight of the storage unit.
