The inaugural instance of photo-thermo-electric conversion has been demonstrated based on the donor–acceptor organic cocrystal strategy due to its unique advantages. Notably, the selected cocrystal exhibits excellent broad solar absorption (200–2500 nm) and high near-infrared photothermal conversion efficiency. Combining organic cocrystals and thermoelectric devices upon 1 sun results in an exceptional open circuit voltage (0.427 V) and output power density (2.21 W·m^–2), which is significantly better than traditional photothermal conversion materials. The fusion of organic cocrystals and high-output power density thermoelectric devices can offer a promising solar-based photo-thermo-electric conversion technology for outdoor portable power generation and remote rural areas.

通过供体-受体有机共晶策略促进光热电转换

由于其独特的优势，基于供体-受体有机共晶策略的光热电转换的首次实例已被证明。值得注意的是，所选的共晶表现出优异的广泛太阳能吸收（200-2500 nm）和高近红外光热转换效率。将有机共晶和热电器件相结合，经过 1 个太阳照射，可产生出色的开路电压 (0.427 V) 和输出功率密度 (2.21 W·m ^–2 )，明显优于传统的光热转换材料。有机共晶和高输出功率密度热电器件的融合可以为户外便携式发电和偏远农村地区提供一种有前途的基于太阳能的光热电转换技术。
