A new material could make solar cells more efficient and cheaper to build.
Photovoltaic cells convert visible light into electricity but the complex materials involved make them expensive to assemble. Fullerene has
A team led by researchers from Sichuan University in China have developed a new fullerene-free ‘small molecular acceptor’. In solar cells, this crucial component takes electrons from the ‘donor’ material, which converts the incoming photons (light particles) to electrons, and carries them to the electrodes. The team wrapped electron-deficient organic molecules — ready-to-absorb electrons from the donor — around a core of
