Scientists Develop Solar Panels with Dual Power-Generation Capability from Sunlight, Rain
—————————————-
Researchers at the University of Seville and the Spanish National Research Council have developed a new hybrid solar technology capable of generating electricity from both sunlight and raindrops, offering a potential breakthrough in continuous renewable energy production.

The innovation combines traditional solar power with triboelectric nanogenerators, which convert the energy from raindrop impacts into electricity. At the center of the system is a thin protective coating applied to perovskite solar cells, improving their durability while also enabling energy generation from rainfall.

According to the research team, the device can produce over 100 volts from a single raindrop impact, enough to power small electronic devices such as sensors or LED circuits. The coating also helps protect the solar cells from environmental damage, including humidity and temperature fluctuations, addressing a major weakness of perovskite-based technology.

Perovskite solar cells are considered a promising alternative to traditional silicon panels due to their high efficiency and lower production costs. However, their sensitivity to environmental conditions has limited widespread use — an issue this new design aims to solve.

Scientists say the hybrid system could provide more consistent energy output, especially in regions with variable weather, where conventional solar panels lose efficiency during cloudy or rainy conditions.

The technology is expected to have applications in Internet of Things (IoT) devices, environmental monitoring systems, smart cities, and remote installations where continuous power supply is essential.
