1. Photons in sunlight hit the solar panel and are absorbed by semi-conducting materials.2. Electrons (negatively charged) are knocked loose from their atoms as they are excited. Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single direction. The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers.

6 FAQs about [Schematic diagram of photovoltaic panel no-load operation principle]
How a solar cell works based on photovoltaic effect?
The working of solar cell is based on photovoltaic effect. It is a effect in which current or voltage is generated when exposed to light. Through this effect solar cells convert sunlight into electrical energy. A depletion layer is formed at the junction of the N type and P type semiconductor material.
What is a solar cell p-n junction diode?
A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance – vary when exposed to light. Individual solar cells can be combined to form modules commonly known as solar panels.
What is the operating principle of a solar cell?
Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
How does a photovoltaic system work?
A photovoltaic (PV) system is able to supply electric energy to a given load by directly converting solar energy through the photovoltaic effect. The system structure is very flexible. PV modules are the main building blocks; these can be arranged into arrays to increase electric energy production.
What is the working principle of solar cells?
Chapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation. The basic processes behind the photovoltaic effect are:
How do solar panels work?
Small rectangles or squares make up each individual solar cell, which is connected by silver strips that carry all the electricity to a single point. The solar cells also have a metal backing on top of these conductive metal strips. Today's typical solar panels are made up of 60 or 72 of these cells connected together.
