#Solarcell ppt series

Several solar cells are mounted on a common panel connected in series or parallel for increasing the voltage or power respectively. Incident photons p Load resistanceĥ Storage of power The amount of power generated by solar cells is determined by the amount of photons absorbed by it. Large area p-n junction is used for effective power generation. When an external is connected through the p-n junction device a current passes through the circuit & generates power when light is incident on it. The number and size required is determined by the available light and the amount of energy required.Ĥ Construction It consists of p-n junction diode in which electrons & holes are generated by the incident photons.

The nominal output voltage of a solar panel is usually 12 Volts, and they may be used singly or wired together into an array. In order to generate useful power, it is necessary to connect a number of cells together to form a solar panel, also known as a photovoltaic module. It is a device which generates electricity directly from Sun’s radiation by means of the photovoltaic effect so it is also called Photovoltaic cell. 1 SOLAR CELL PRESENTED BY ANJALI PATRA ANKITA TRIPATHY BRANCH-EEEĢ CONTENTS What is a solar cell?
