Spectrolab, Inc. and the National Renewable Energy Laboratory develop a photovoltaic solar cell that converts 32.3 percent of the sunlight that hits it into electricity.
The history of solar energy is a fascinating journey that dates back thousands of years, revealing humanity’s early understanding and utilization of the sun’s power. Ancient civilizations recognized the sun as a vital source of energy, and they developed various practices to harness its warmth and light.
Researchers built on earlier findings to create devices capable of harnessing sunlight for electricity generation. The first practical solar cells emerged in 1883 when Charles Fritts created a selenium-based photovoltaic (PV) cell. Its efficiency reached about 1%, far lower than today’s cells but crucial for proving the technology could work.
Solar power development reached new heights in the late 20th century as advancements in technology made it more accessible and efficient. Global interest in renewable energy surged during this period, driving significant progress in various sectors.
In 213 BC, Greek scientist Archimedes set enemy ships on fire using only sunlight and bronze mirrors. This was humanity’s first recorded ‘solar weapon’—and the start of a 2,000-year quest to harness the sun’s power. Today, solar panels power homes, cars, and even space stations. But how did we get here?
Innovations from ancient civilizations to groundbreaking scientific discoveries laid the foundation for modern solar power. Ancient civilizations used sunlight for practical applications. Around 7th century BCE, humans started concentrating sunlight with magnifying glasses to create fire.
Many argue that this event marks the true invention of PV technology because it was the first instance of solar technology that could actually power an electric device for several hours of a day. The first ever silicon solar cell could convert sunlight at four percent efficiency, less than a quarter of what modern cells are capable of.
