A promising material for solar energy gets its boost from entropy, the outstanding performance partly achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs). These “organic” carbon-based semiconductors are Earth-abundant, cheaper and more environmentally friendly than silicon solar panels. The materials can be coated on arbitrary surfaces (like walls), and can be tuned to absorb light at selected wavelengths, which can be used to create transparent solar panels or panels with different colors.
