MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202541053058 A) filed by Mahatma Gandhi University, Kottayam, Kerala, on May 31, 2025, for 'hybrid renewable energy harvester.'
Inventor(s) include Aathmaj B.; K. P. Jayachandran; K. Pramod; Sreekala M. S; and Sabu Thomas.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "Present invention discloses a hybrid renewable energy generating device (100) that combines solar energy harvester using a Dye-Sensitized Solar Cell (DSSC) (104) with a Piezoelectric Energy Generator (PEG) (102), made of an enhanced Polyvinylidene fluoride (PVDF) film. The device (100) increases total energy output by capturing both solar energy and mechanical vibration from rainfall and/or wind. The device (100) is energized to maintain electrical energy output during lean periods of dimmer sunlight in rainy seasons. Additionally, the PEG provides a transparent energy generator that can be implanted on top of existing solar plants by attaching it above the cells without need of additional space and thereby make the solar cell to harvest wind and/or rain energy. The piezoelectric component is optimized to obtain high efficiency in acquiring energy from rainfall and is laminated inside a transparent conducting polymer which can pass radiation from sun and fall onto the DSSC (104)."
