PHOTOVOLTAICS Meaning and
Definition
-
Photovoltaics, also known as solar photovoltaic (PV) technology, refers to the direct conversion of sunlight into electricity. It is a renewable energy technology that harnesses the power of the sun to generate electrical energy.
Photovoltaics utilize photovoltaic cells, which are made of semiconducting materials like silicon. These cells absorb photons from the sun and convert them into electric current. When sunlight hits the semiconducting material, the photons transfer their energy to electrons, allowing them to move freely and generate an electrical current.
The electrical energy produced through this process can be used to power various devices, from small electronic devices like calculators to larger applications like residential and commercial buildings. The amount of electricity generated depends on the size of the photovoltaic system, sun exposure, and the efficiency of the photovoltaic cells.
Photovoltaic systems can be installed in different configurations, including rooftop solar panels or large solar farms. In recent years, the efficiency and cost-effectiveness of photovoltaic technology have increased significantly, making it one of the fastest-growing renewable energy sources worldwide.
As a clean and renewable energy solution, photovoltaics play a crucial role in reducing greenhouse gas emissions, combating climate change, and achieving sustainable energy goals. They offer a sustainable and environmentally friendly alternative to traditional fossil fuel-based energy sources.
Common Misspellings for PHOTOVOLTAICS
Etymology of PHOTOVOLTAICS
The word "photovoltaics" has its roots in Greek and Latin. It is a combination of the Greek word "photos", meaning "light", and the Latin word "voltaic", which refers to electricity produced by chemical action. The term was coined in the mid-19th century by a French physicist named Alexandre Edmond Becquerel, who discovered the photovoltaic effect while experimenting with the electricity generated by certain materials when exposed to light. Over time, "photovoltaics" became the commonly used term to describe the process of converting light into electricity using semiconductors, such as solar panels.
