The energy conversion efficiency of conventional solar cells is traditionally bound by the Shockley-Queisser limit, impeding the effective utilization of photons in the long-wavelength spectrum. To overcome this limitation, a research team led by Li Can from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, introduced a novel concept: coupling the photoelectric and thermoelectric effects. By harnessing the thermoelectric properties and low thermal conductivity of perovskite materials, they established a vertical temperature gradient within the solar cell, thereby activating the thermoelectric effect. This innovative approach converts infrared thermal energy from the long-wavelength region into electrical energy, while simultaneously converting photons in the short-wavelength region into electrical energy through the photovoltaic effect. This dual mechanism enables efficient utilization of the entire solar spectrum. Experimental findings reveal that the energy conversion efficiency of FAPbI₃-based solar cells rose from 25.65% to 27.17% following the integration of the thermoelectric effect.
