Summary:
- The article discusses the development of a new type of solar cell that can generate electricity from raindrops.
- The solar cell uses a material called perovskite, which can convert the energy from raindrops into electricity through a process called the "water-drop electricity effect."
- This technology has the potential to expand the use of solar power, as it can generate electricity even in cloudy or rainy conditions, where traditional solar panels are less effective.
