The solar energy industry is evolving rapidly. While silicon solar panels have dominated for decades, a new technology—perovskite solar cells—is gaining attention due to its high efficiency and low cost potential.
What Are Perovskite Solar Cells?
Perovskite solar cells use a unique crystal structure material that absorbs sunlight and converts it into electricity. These cells are lightweight, flexible, and easier to manufacture compared to traditional silicon panels.
