    Abstract: A photovoltaic cell has an active area formed electron donor-fullerene conjugated molecules. The electron donor is formed of a polymer, which is conjugated with an electron acceptor, such as fullerene. By conjugating the fullerene, such as C60, with electron donor moieties, such as that of the polymer, double channels are formed therebetween, whereby one channel provides hole transport and the other channel provides electron transport. As a result, the electronic coupling between the fullerene and the electron donor moiety leads to increased short-circuit current density (Jsc) and increased open-circuit voltage (Voc), resulting in high power conversion efficacy (PCE) in the solar cell.

Among the non-conjugated polymers are polyisoprene, poly(?-pinene), cis-polyisoprene, styrene-butadiene-rubber copolymer, polynobornene and polyalloocimene. When light strikes this photovoltaic structure it is capable of generating electric voltage greater than 100 mV for a light intensity of about 5 mW/cm2.

  • Publication number: 20140116510
    Abstract: A bulk heterojunction solar cell comprises an electron donor, an electron acceptor, and a multi-substituted fullerene derivative. The electron acceptor further comprises a nano-scale electron acceptor material, and a meso-scale mixture of electron donor/acceptor material. The multi-substituted fullerene derivative further comprises a single fullerene structure and a multi-substituted derivative connected to the single fullerene structure. The multi-substituted fullerene derivative is utilized to prevent the meso-scale mixture of electron donor/acceptor material from large-scale segregation of acceptor over a specific temperature after a specific period (thermally unstable state), thereby maintaining the thermal stability and the sizes of the nano-scale acceptor material and meso-scale mixture of electron donor/acceptor material. In the conventional knowledge, the large-scale segregation and corresponding degradation of power efficiency are cause mainly by the nano-scale acceptor material.
