1. Early Exploration:
The concept of harnessing solar energy dates back to ancient civilizations, who used magnifying glasses and mirrors to focus sunlight for various purposes. However, it was not until the 19th century that scientists began experimenting with photovoltaic effects. In 1839, Alexandre-Edmond Becquerel discovered the photovoltaic effect, laying the groundwork for future solar technologies.
2. The Birth of Photovoltaics:
The true birth of solar panels came in 1954 when researchers at Bell Laboratories, led by Daryl Chapin, Calvin Fuller, and Gerald Pearson, developed the first practical silicon photovoltaic cell. This revolutionary discovery marked the first commercially viable solar cell, capable of converting sunlight into electricity. The Bell Solar Battery, as it was known, achieved a 4% energy conversion efficiency.
3. Space Exploration and Solar Revolution:
During the space race of the 1950s and 1960s, solar panels gained prominence as a vital power source for satellites and spacecraft. The Vanguard I satellite, launched in 1958, featured small photovoltaic cells. Subsequently, solar panels were extensively used in various space missions, including the Apollo program. These space applications drove further research and technological advancements, leading to improved solar cell efficiency and durability.
