Red Solar Flower

Red Solar Flower (RSF) is an Israel-based company based on technology and a patent developed in the perovskite solar lab at the Hebrew University in Jerusalem. The company aims for the agrovoltaics sector, developing a semi-transparent, perovskite-based solar panel that provides a synergetic and profitable dual-use solution.

Through a printing-like technique, RSF solar panels are made by applying sub-micron layers on a substrate. RSF's patented application harnesses the unique properties of perovskite composition to create semi-transparent solar panels that transfer the light essential for photosynthesis. Unlike state-of-the-art PV panels, RSF synergetic solution ensures crops get vital sunlight while the solar panels convert sunlight into electricity.

RSF’s patented perovskite-based solar panel transfers only the wavelengths required for photosynthesis while utilizing the rest of the spectrum for power generation, thereby enabling 100% coverage of the growing area while maintaining the light conditions required for plant growth.

The company’s solution aims to provide the highest possible power production per growing area unit, reduces heat load and water usage, and protects crops against weather hazards such as hail, heavy rain, frost, and sunburn.

The panels are said to be about 40% of the cost of comparable silicon-based panels due to the inexpensive and abundant materials used, simple manufacturing method, and passive structure with no moving parts or engines.
