We fabricated a C fullerene-based molecular spin-photovoltaic device that integrates a photovoltaic response with the spin transport across the molecular layer. The photovoltaic response can be modified under the application of a small magnetic field, with a magnetophotovoltage of up to 5% at room temperature. Device functionalities include a magnetic current inverter and the presence of diverging magnetocurrent at certain illumination levels that could be useful for sensing. Completely spin-polarized currents can be created by balancing the external partially spin-polarized injection with the photogenerated carriers.
我们制备了一种基于 C60 富勒烯的分子自旋光电装置，该装置将光电响应与分子层中的自旋输运结合在一起。在施加小磁场的情况下，光电响应可以被调制，在室温下磁光电压高达 5%。该器件具有磁流反向器的功能，并且在特定的光照水平下存在磁电流发散，这对于传感可能是有用的。通过平衡外部部分自旋极化注入和光生载流子，可以产生完全自旋极化的电流。
