How Solar PV Panels Work? Everything You Need To Know
What is the Photovoltaic Effect?
Photovoltaics (PV) is the process of converting sunlight into electricity. The term comes from the Greek words “photo”(light) and “volt” (electricity), referring to the photovoltaic effect.
When sunlight hits materials like silicon, it excites electrons, creating an electric current. This principle is the foundation of solar cells, which power solar panels and photovoltaic systems, allowing us to harness solar energy for various uses.
As the cost of solar panels continues to fall, this technology is becoming more accessible, offering a cleaner, sustainable alternative to non-renewable energy sources and helping to address environmental challenges.
So, to sum it all up, the photovoltaic effect in solar cells work in three steps:
- Photons from sunlight penetrate the photovoltaic cell
- Loose electrons flow generating an electrical current
- The generated electric current is captured and directed through wires
How Does Photovoltaics Work?
In photovoltaic technology, semiconductors leverage the photoelectric effect. When photons, whether from natural or artificial light, penetrate a photovoltaic cell, they excite electrons to a higher energy state. Electrons in the semiconductor, typically not free, become liberated, mimicking conductive behavior. These free electrons are captured, generating an electric current. The extent to which electricity is produced is measured by the amount of light absorbed. Greater light absorption translates to increased electricity yield.
The same concept is applied to solar cells. Solar panels, composed of photovoltaic cells usually made from silicon, transform sunlight into DC electricity. PV cells, with one or two layers of semiconducting material like silicon, create an electric field when exposed to light, facilitating the flow of electricity. An inverter then converts it into AC electricity, suitable for household use.
Types of Solar Cells (Monocrystalline vs. Polycrystalline)
When it comes to understanding how solar PV panels work and harnessing solar energy, understanding the different types of solar cells is crucial. These cells are at the heart of solar panels, transforming sunlight into usable electricity. The two most common types of solar cells that are used today in residential and commercial installations are monocrystalline and polycrystalline solar cells.
Monocrystalline Solar Cells
Monocrystalline solar panels are made from a single crystal structure, offering a uniform appearance and high efficiency. Their design ensures efficient electron transport, making them ideal for space-constrained applications.
Polycrystalline Solar Cells
Polycrystalline solar cells are made from multiple crystal forms. While they are less efficient than monocrystalline cells, they are cost-effective and offer good performance and efficiency.
