A cutting-edge breakthrough from a research collaboration between Osaka University, Suwa University of Science, Ishihara Sangyo, and Design Solar has led to the development of an organic solar cell that not only generate electricity but also support the cultivation of crops.

The key to this technology lies in how sunlight is utilized. Blue and red light, essential for photosynthesis, is transmitted to the crops, while green light is harvested for power generation. This dual functionality enables farmers to maintain crop growth while generating clean energy simultaneously. The organic solar cells are lightweight and flexible, making them ideal for installation in agricultural greenhouses. Their adaptability and efficiency are expected to accelerate the adoption of solar sharing, a farm-based photovoltaic power generation system.

This exciting advancement opens the door to a sustainable future where energy and food production go hand in hand, contributing to the global push for renewable energy and smart farming. With this innovation, Agri-solar so called “solar sharing” in Japan is set to expand, offering significant benefits to both farmers and energy providers, while promoting a greener, more sustainable agricultural practice.
