This breakthrough led to the commercialization of solar cells and their initial use in space applications, such as powering satellites. Throughout the 1960s and 1970s, solar cell technology continued to advance, primarily driven by research and development efforts in the United States. The energy crisis of the 1970s further fueled interest in renewable energy, including solar cells, leading to increased investment and technological advancements. In the 1980s and 1990s, solar cells became more efficient and affordable, making them increasingly popular for off-grid applications, such as powering remote locations and providing electricity to rural communities. Governments and organizations worldwide started implementing policies and incentives to promote solar energy adoption. In the early 2000s, there was a significant growth in the solar industry, driven by technological improvements, increased manufacturing scale, and declining production costs. This led to the widespread adoption of solar panels for residential and commercial use, as well as grid-connected solar power plants. Today, solar cells continue to evolve, with ongoing research focused on improving efficiency, durability, and reducing costs. The integration of solar cells into various applications, such as building materials and consumer electronics, further expands their potential. The solar industry plays a crucial role in the global shift towards clean and sustainable energy sources.
