Solar energy began to attract interest in the 19th century when scientist Edmond Becquerel discovered the photovoltaic effect. Albert Einstein later recognized this effect and received the Nobel Prize in 1922. In the early 20th century, solar energy technology developed with the first silicon panels with an efficiency of only 4%.
During the 20th century:
Incredible advances in solar energy have occurred in the 21st century. Solar panels now power millions of homes worldwide and prices have dropped 90% since 2010. by 2020. The main types of solar panels on the market include monocrystalline, polycrystalline and thin panels, each with its own advantages and disadvantages.
In the 21st century:
In the 21st century, solar energy has undergone outstanding development after 50 years of research into silicon and other PV materials. Today’s solar panels power millions of homes and buildings worldwide, and provide clean energy to satellites and the globe.
It is expected that global solar installed capacity will increase from about 728 GW to 1,645 GW by 2026. The price of silicon PV cells has dropped significantly from US$76/Watt in the 1950s to zero .20 US$/Watt by 2021. Advances in manufacturing efficiency, automation and new technology have helped reduce labor and material costs for the solar industry, while also increasing efficiency. capacity of the panels.
The Future of Solar Energy
Solar energy has made incredible progress and will play an important role in the energy transition currently underway.
