Student Creates Solar Panels Made From Food Waste That Can Produce Energy Even On Cloudy Days
Carvey Ehren Maigue is a 27-year-old Filipino student at Mapua University
Maigue’s creation that won him the sustainability prize is called AuREUS, and it’s a system that absorbs stray UV light from sunlight and converts it to clean renewable electricity—even when the weather is cloudy. And one of the best things about it all is that his solar panels are made out of fruit and vegetable waste.

This year, Maigue became the winner of the sustainability prize of the international James Dyson Award

Turns out, Maigue’s invention uses the natural scientific principles behind the northern lights. “1 Excess UV exposure in urban areas is being induced by glass buildings. The inspiration for the solution came from how auroras were made. High energy (gamma, UV) is degraded to a low-energy state (visible light) by luminescent particles in the atmosphere. The tech is based on this concept and used similar functioning particles,” the guy describes the inspiration behind his creation on the James Dyson Award webpage.
Maigue came up with a genius way to turn fruit and vegetable waste into energy
These new solar panels are made from fruit and vegetable waste and can be attached to windows and walls. “High-energy particles are absorbed by luminescent particles that re-emit them as visible light. Similar type of luminescent particles (derivable from certain fruits and vegetables) were suspended in a resin substrate and are used as the core technology,” Maigue explains the science behind his creation.
The invention is called AuREUS, and it’s a system that absorbs stray UV light from sunlight and converts it to clean renewable electricity
“When hit by UV light, the particles absorb and re-emit visible light along the edges due to internal reflectance. PV cells are placed along the edges to capture the visible light emitted. The captured visible light are then converted to DC electricity. Regulating circuits will process the voltage output to allow battery charging, storage, or direct utilization of electricity,” the guy explains.
The system continues to work even during cloudy weather
In other words, by using luminescent particles derived from fruit and vegetables, the AuREUS system allows high energy photons to be absorbed. And since it can pick up UV through clouds and bouncing from various surfaces, the system works even when the weather is cloudy.
And one of the best things about this system is that the solar panels are made out of food waste
“We can use AuREUS instead of typical glass windows so that the whole building can become a vertical solar energy farm. AuREUS can become a part of our clothes, our cars, buildings, and our houses. This is the change we can make for the future,” the guy adds.
The James Dyson Award
The James Dyson Award is an international design award that celebrates, encourages and inspires the next generation of design engineers. It's open to current and recent design engineering students, and is run by the James Dyson Foundation, James Dyson’s charitable trust, as part of its mission to get young people excited about design engineering.
