So, let’s delve into the timeline of solar panels and discover the innovations and discoveries that have paved the way for their widespread use today.
When was solar energy first used?
Solar energy, or the conversion of sunlight into usable energy, has been around for thousands of years. The earliest known use of solar energy can be traced back to ancient civilizations such as the Greeks and Romans, who used sunlight to light fires using magnifying glasses made of glass or polished bronze. However, it wasn’t until the 1800s that scientists began to truly understand and harness the power of solar energy.
In 1839, French physicist Alexandre Edmond Becquerel discovered the photovoltaic effect, which is the process of converting sunlight into electricity using certain materials. This discovery laid the foundation for the development of solar panels as we know them today.
Fast forward to 1883, when American inventor Charles Fritts created the first working solar cell using selenium, a semiconductor material, and coated with a thin layer of gold. This solar cell had an efficiency of around 1-2%, meaning it could convert 1-2% of sunlight into electricity. While this may seem insignificant, it was a groundbreaking achievement at the time.
In the early 1900s, scientist Albert Einstein published a paper on the photoelectric effect, furthering our understanding of the behavior of light and its interaction with materials. This led to the development of more efficient solar cells, with efficiencies reaching up to 6% in the 1950s.
During this time, the first practical use of solar energy was demonstrated at Bell Laboratories in 1954. Scientists Gerald Pearson, Daryl Chapin, and Calvin Fuller created a silicon-based solar cell with an efficiency of 6%, which was used to power small devices such as toys and radios.
The 1960s marked a significant milestone in the use of solar energy, with the launch of the first satellite powered by solar cells. The Vanguard 1 satellite, launched in 1958, used a small solar panel to power its radio transmitter and became the first man-made object to use solar energy to generate electricity.
In the 1970s, the oil crisis and concerns about environmental pollution prompted increased interest in renewable energy sources, including solar energy. This led to the development of the first commercial solar panels, which were used to power remote locations such as lighthouses and weather stations.
In the 1980s, advancements in technology and manufacturing processes led to solar panels becoming more affordable and efficient. This was also the decade when the first solar-powered calculators were introduced, paving the way for the use of solar energy in everyday devices.
The 1990s saw further improvements in solar panel technology, with the introduction of thin-film solar cells, which are made using a much thinner layer of semiconductor material than traditional cells. This made them lighter, more flexible, and cheaper to produce.
As we entered the 21st century, the use of solar energy became more widespread, with many countries investing in solar farms and rooftop solar installations. In 2004, Germany became the first country in the world to reach 1 gigawatt (GW) of installed solar power capacity, followed by the United States in 2005.
Today, solar energy is one of the fastest-growing sources of renewable energy globally. According to the International Energy Agency, solar energy accounted for 45% of new power capacity additions in 2019, surpassing all other forms of energy. Countries like China, Japan, and the United States are leading the way in solar energy installations, with the cost of solar panels decreasing significantly over the years.
while the use of solar energy dates back to ancient civilizations, it wasn’t until the 1800s that scientists truly began to understand and harness its power. With ongoing advancements in technology and increasing concerns about climate change, it is clear that solar energy will continue to play a crucial role in our present and future.
