When the photons strike a solar cell, some are absorbed while others are reflected.When the material absorbs sufficient photon energy, electrons within the solar cell material dislodge from their atoms. The electrons migrate to the front surface of the solar cell, which is manufactured to be more receptive to the free electrons.When many electrons, each …

The basic structure of a PV cell can be broken down and modeled as basic electrical components. Figure 4 shows the semiconductor p–n junction and the various components that make up a PV cell.
Cell Membrane: The cell membrane or plasma membrane is a selectively permeable lipid bilayer that encloses the contents of the cell and regulates the transport of materials into and out of it.; Cytoplasm: The cytoplasm is the jelly-like fluid that gives a cell is shape and contains the molecules the cell needs for its processes.
Using the same logic, a team of MIT researchers have stacked a bunch of photovoltaic solar cells together to produce up to 20 times the power output of conventional solar power installations.
Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy. The basic principle behind the function of solar cell is based on photovoltaic effect. Solar cell is also termed as photo galvanic cell. The electricity supplied by the solar cell is…

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
