This document provides an overview of fundamentals of solar PV systems. It discusses solar energy basics and the solar spectrum. It describes the construction and working principle of photovoltaic cells made of semiconductors like silicon.
Photovoltaic Cell Defined: A photovoltaic cell, also known as a solar cell, is defined as a device that converts light into electricity using the photovoltaic effect. Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
Create a basic design plan for a residential solar photovoltaic system, considering factors like location, orientation, and system size. c. Compare the advantages and disadvantages of fixed-tilt and tracking solar panel systems. Energy Yield and Calculations: a.
The photovoltaic (PV) solar system is made up of a total of three components: (I) photovoltaic cells or solar arrays, (II) the system’s overall equilibrium, and (III) the load. Installing photovoltaic panels, which give clean, green electricity, is one of the most important advantages because it offers significant cost savings.
This interaction between sunlight and solar cells is termed the photovoltaic effect. The phenomenon was discovered by Edmond Becquerel in 1839. When we close the circuit by connecting the upper and rear end of the solar cell, the excited electrons flow into the circuit. The diagram below depicts the same. Simple working of a solar cell
