They are thin-film, monocrystalline and polycrystalline,ģ). What is the difference between a solar cell and photovoltaic cell?Ī PV cell is a subset of solar cells whereas a solar cell converts solar emission to functional energy. The applications of the solar cells include the following.ġ). In this parallel connection, the output current of the solar cells is twice but their i/p voltage is the same. The connection of solar cells in parallel can be done by connecting all the +Ve terminals of the panels jointly whereas all the –Ve terminals of the panels jointly. When two or more solar cells are connected in parallel then it is called a parallel combination of solar cells.

In this connection, the output current of the solar cells is the same but their i/p voltage becomes twice.įor example: If we connect four solar panels in a series combination then each solar panel rated at 10 V & 5 amps, then the total array of panels would be 40 volts at 5 amps. The connection of solar cells in series can be done by connecting the +Ve terminal of the panel to the –Ve terminal of the second panel. When two or more solar cells are connected in series then it is called a series combination of solar cells. There are different kinds of semiconductor materials used in solar cells like Silicon, Photovoltaics like Thin-film, Organic, and Concentration photovoltaics. Once the energy from the sun falls on the panel then a semiconductor absorbs, the energy of photons transfers to electrons and allows the flow of electrons through the material like an electrical current. So it makes to convert the light energy into electrical. Each panel in the solar panel includes semiconductor material to combine the properties of insulators and metals. Once the solar energy falls on a solar panel, then it absorbs. Based on the application, solar cells utilize various materials based on their application & cost. A rear metallic electrode is beneath the p-type semiconductor and it works with the metallic grid to generate an electric current in the pinnacle layer.Ī reflective layer is the last layer in this cell used to decrease the loss of light within the system. The base layer of this cell consists of two parts. It consists of two semiconductor layers which are made up of p-type and n-type materials. The most important part of the cell is the middle layer where solar energy can be formed through the effect of photovoltaic.

So that the top layer of this cell can be formed by using the glass, metallic strips & anti-reflective coat. In this cell, small grid patterns with slight metallic strips are available under the glass. This glass guards the semiconductor materials against the sunlight. The pinnacle layer of this cell includes an anti-reflective cover glass.

The construction of a solar cell is shown below. A single solar cell generates a voltage of around 0.5 volts to 0.6 volts.

A solar panel can be formed by combining a number of cells. The electrical characteristics of solar cells like the voltage, resistance, and current will change when exposed to sunlight. These cells play an essential role in converting the energy from solar to electrical is known as PV effect. Definition: A component that is used to design a solar panel is known as a solar cell or PV cell.
