Key Milestones

One of the earliest milestones was in 1839 when Alexandre-Edmond Becquerel, a French physicist, discovered the photovoltaic effect. This is the principle that allows solar panels to convert sunlight directly into electricity. Becquerel found that certain materials produce an electric current when exposed to light. This discovery laid the groundwork for all future solar energy technology.

Fast forward to 1883, when Charles Fritts, an American inventor, created the first solar cell using selenium wafers. His invention was able to produce a continuous electric current but was not very efficient. Despite its limitations, Fritts' solar cell was a significant step forward, demonstrating the potential of converting sunlight into usable energy.

Why It Wasn't Israel

So, where does Israel fit into all of this? Well, during the 19th century, the region we now know as Israel was under Ottoman rule, and later, the British Mandate. The focus was more on survival and development under challenging political and social conditions rather than scientific innovation on a global scale. The early pioneers of solar energy were primarily in Europe and America, where the industrial revolution was driving scientific discovery and technological advancement.

Israel's Solar Energy Contributions

While Israel didn't invent solar energy, it has become a global leader in solar energy research, development, and implementation.
