Harnessing the Sun: The Evolution and Impact of Solar Energy

Every second, the sun radiates more energy than humanity has consumed in its entire history. This energy fuels life on Earth, offering a virtually inexhaustible source of power.

The photovoltaic effect, essential for solar panels, was discovered by French physicist Edmond Becquerel in 1839. At just 19, he observed electricity generation from light, laying the foundation for solar power.

The first practical solar cell was introduced in 1954 at Bell Labs. With an efficiency of just 6%, it was a breakthrough that led to today’s average efficiency of over 20%.

Space technology relies heavily on solar energy. The International Space Station's solar arrays provide all the necessary power, showcasing solar energy's reliability even beyond Earth's atmosphere.

While multiple materials can be used for photovoltaic cells, silicon dominates the market due to its abundance and efficiency. It's used in more than 90% of solar panels worldwide.

Investments in solar energy are accelerating the shift to sustainable energy, with solar power expected to supply one-third of the global electrical demand by 2060, transforming our energy landscape.

Solar panels produce electricity without water or emissions, reducing environmental impact. However, their manufacturing and recycling processes still present sustainability challenges that are being actively addressed.

A single solar flare releases energy equivalent to millions of 100-megaton hydrogen bombs, showcasing the sun's immense power and unpredictability.
