Abstract

Searching new light-absorbing materials to replace toxic lead halide in solar cells is very important and highly desirable. In this research, we firstly demonstrated that tellurium iodide (TeI₄) could be used as a light-absorbing material in solar cells due to its suitable optical band gap and the active lone-pair electron orbital in Te⁴⁺. The best power conversion efficiency (PCE=3.56%) was achieved with a concentration of 0.9 M TeI₄ in DMF:DMSO (4:1, v,v) without any heat treatment or antisolvent dripping. Our study indicates the promising potential of TeI₄ for photovoltaic and optoelectronic applications.
