Applications

N2200, a copolymer of naphthalene diimide (NDI) and bithiophene unit, has been intensively studied for use as an electron acceptor in polymer solar cells. This is due to its high electron mobility, high electron affinity, and broad light absorption. All polymer solar cells with N2200 as an acceptor and J51 as a donor (fullerene-free) have demonstrated a power conversion efficiency over 8% [1].

N2200 is also known as a high-mobility n-type polymer semiconductor. N2200-based OFET devices have electron mobilities up to 0.45–0.85 cm2V-1 s-1[2].
