Solar panel design is about to be radically transformed. Researchers at Cornell University have developed HelioSkin, a bio-inspired photovoltaic fabric that combines flexibility, efficiency and aesthetic design to transform solar energy harvesting .
The HelioSkin project proposes an innovative solution to one of the major challenges of photovoltaic energy : the rigidity of traditional panels. Inspired by heliotropism, the phenomenon by which certain plants follow the movement of the sun, the interdisciplinary Cornell team has designed a material that adapts to complex shapes and optimizes light absorption.
Technology applied to design and architecture
This development is the result of a collaboration between architect Jenny Sabin, physicist Itai Cohen and plant biologist Adrienne Roeder, who have applied principles of biology, engineering and computational design to create a modular and flexible system. The structure of the fabric is based on origami and kirigami concepts , allowing the solar surfaces to expand and contract according to the lighting needs of the environment.

The impact of HelioSkin goes beyond energy efficiency. Its lightweight and adaptable design allows for integration into retractable roofs, architectural facades and even street furniture. With the ability to wrap around curved surfaces and generate energy in previously untapped spaces, this photovoltaic fabric could facilitate the transition to more sustainable cities .
Industrial and commercialization drive
HelioSkin has already received initial funding of $650,000 from the National Science Foundation’s Convergence Accelerator program. With a view to commercialization, the team is seeking to increase the investment to $5 million over the next three years, with the goal of developing scalable prototypes.
Companies such as E Ink, Rainier Industries and SunFlex are involved in optimizing the system, integrating e-paper technology and advanced photovoltaic modules . Additionally, market analysis has identified innovative applications, such as panels that can function as solar billboards with dynamic content.
The Cornell researchers’ vision not only offers a more efficient energy solution, but also a renewed aesthetic for the use of solar energy in architecture and urban design. With a focus on sustainability and accessibility, HelioSkin could mark a turning point in the adoption of adaptive photovoltaic technologies. worldwide.
