History of Solar Panels
Early Developments
A few centuries ago, the early discoveries that paved the way for solar panels as we know them today were made. An important milestone in the history of solar panels was the discovery of the photovoltaic effect in 1839 by French physicist Alexandre Edmond Becquerel. This effect describes the generation of an electric current in a material when exposed to light. It wasn’t until the late 19th century that the first solar cell was built by Charles Fritts using a thin layer of gold on selenium to form a photovoltaic cell that converted light into electricity.
Modern Advancements
Advancements in solar panel technology have come a long way since the early experiments with selenium and gold. Today, solar panels are typically made using silicon, a much more efficient and reliable material for capturing solar energy. Silicon solar cells were first introduced in the 1950s, but it wasn’t until the space race of the 1960s that their efficiency was significantly improved. Companies like Bell Labs and RCA played a crucial role in the development of modern solar panels, making them more accessible and cost-effective for a wider range of applications.
Modern advancements in solar panel design continue to focus on improving efficiency, durability, and affordability. Scientists and engineers are constantly working on new materials and technologies to make solar panels even more efficient at capturing and converting sunlight into usable energy. Innovations like thin-film solar cells, bifacial solar panels, and solar shingles are just a few examples of the cutting-edge technologies being developed to make solar power a more viable and sustainable energy option for the future.
