Description
Yongsheng Chen writes a 2026 commentary on a design idea for cheaper organic solar cells. Light, bendy solar films could be made cheaply with simple materials, but those materials twist into many shapes, which disorders them and weakens power output. Costly ring-fused materials avoid this but are hard to make at scale.
A study he discusses borrowed a lesson from protein folding: cut the number of shapes a molecule can take, a measure called conformational entropy. The tuned molecule settled into one flat shape, packed neatly, and hit a record efficiency near 19 percent for its class, at a far lower cost. Chen presents the measure as a guide for future solar materials.
