Harnessing the Sun's Power
Solar energy isn't a modern concept. As early as 7th century B.C., humans used sunlight to light fires with magnifying glass materials, harnessing the sun's vast energy.
Photovoltaic Effect Discovery
The photovoltaic effect, essential for modern solar panels, was discovered by French physicist Edmond Becquerel in 1839, laying the groundwork for solar energy conversion.
Space's Solar Milestone
Space technology advanced solar power. The first solar-powered satellite, Vanguard 1, launched in 1958 and remained in orbit for years, powered solely by solar cells.
Solar Energy and Water
Solar energy plays a crucial role in water sanitation. Solar disinfection uses sunlight to treat contaminated water, significantly improving water quality in remote areas.
Invisible Light Harvesting
Not all solar tech relies on visible light. Researchers are developing panels that can harness infrared and ultraviolet light, vastly increasing potential energy capture.
Solar Roads Unveiled
Imagine driving on solar panels. The world's first solar road opened in France in 2016, integrating panels into the pavement to collect energy from traffic.
Plants' Efficiency Rivalry
Current solar panels have a maximum efficiency of about 22%, while plants achieve only 1-2% with photosynthesis. Solar technology seeks to surpass nature's design.
