Introduction
When sunlight enters a PV cell, the light can separate an electron from an atom and the electric field helps move the electrons to charge collecting areas. The electrons are then gathered on the surface of the solar cell by a grid of metal connected to a circuit.
Describe the construction and operation of the PV cell. Enumerates the different factors that may affect the operation of the PV cell. Solar cells are generally made from semiconducting materials, which are sensitive to structural and environmental factors, e.g, the light intensity, which depends on the power delivered by the solar cell.
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.
Sunlight hits the solar cell – if the energy of the photon is high enough (≥band gap energy), it is absorbed on the P-side. This sends the “holes” towards the N-side. A potential difference (voltage) is thereby created across the p-n junction that drives the current and propels the excess free electrons to the conductor on the top of the cell.
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.
