The Evolution of Solar Energy: From First Solar Cell to Space-Based Power Harvesting
Harnessing the Sun
In 1839, a 19-year-old French physicist named Alexandre Edmond Becquerel discovered the photovoltaic effect, which is the creation of voltage or electric current in a material upon exposure to light. This discovery laid the groundwork for the development of solar technologies. Over the years, the evolution of solar technologies has been marked by significant milestones, from early innovations in the 1860s driven by a scarcity of traditional energy sources to the impactful energy crises of the 1970s and 1980s that spurred government policies and research.
Fast forward to the present day, and solar energy has become a mainstream power source. One of the most significant advancements is in solar PV, which has seen drastic reductions in costs and has become a leading source of electricity generation worldwide. Solar PV systems are technologically distinct from solar thermal systems and offer substantial economic advantages, making them a preferred choice for many applications.
Today, solar panels are not just limited to small gadgets and rooftops; they are also used in large-scale solar farms that generate significant amounts of electricity. The relationship between geography and solar energy potential is crucial, as different locations receive varying amounts of solar radiation. Regions near the equator typically have higher solar radiation exposure, but technology like solar panels that track the Sun can enhance energy capture even in less favorable locations.
Then (1839): The First Solar Cell
The journey of solar energy begins in the 19th century when Alexandre Edmond Becquerel, a French physicist, made a groundbreaking discovery in 1839. Becquerel observed that certain materials, when exposed to sunlight, produced an electric current. This phenomenon, known as the photovoltaic effect, marked the birth of the first solar cell.
Becquerel's solar cell was a simple apparatus, consisting of two metal electrodes placed in an electrolyte solution. When exposed to sunlight, it generated a small but significant electric current. This discovery laid the foundation for the development of solar technology, although it would be many years before solar cells became practical for everyday use.
