Renewable energy sources, like solar power, are playing an increasingly crucial role in our transition to a sustainable future. However, effectively harnessing the power of the sun comes with its challenges, particularly in optimizing the performance of photovoltaic (PV) systems. Researchers have now developed an innovative optimization technique inspired by the behavior of jellyfish in the ocean, which could significantly improve the efficiency of solar power generation.
