The polymer solar cell is able to retain 97% of its performance after 2,000 hours in air. By blending small-molecule acceptors into polymeric matrices, the research team improved molecular packing, enhancing both stability and charge transport for "ultra-stable" flexible devices.
It’s an important proof of concept. If it can survive 2,000 hours in air, then it may be possible to tweak it so it survives 20,000 in air and 2,000 in rain. Then tweak it again and it survives 200,000 hours. Engineering is iterating on a design, not developing the final product out of the gate.
