Introduction to Solar Cells

The I-V characteristics of a solar cell are actually the graph plotted between the current and voltage of the solar cell at a particular temperature and intensity of radiation. I-V characteristic curves help in providing information regarding the operating conditions where a solar panel can perform to its optimum capacity known as maximum peak power point (MPP).

Solar cell

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light dividual solar cell devices are often the electrical building blocks of
