However, the road to sustainable, high-efficiency photovoltaics has been riddled with roadblocks such as toxicity and instability in widely used lead halide perovskites. Could we engineer a solar cell that delivers not just high performance, but also durability, stability and environmental safety?<\/p>\n<p>That question led us to (Ca, Ba)ZrS<sub>3<\/sub>, a chalcogenide perovskite with immense promise. Unlike its lead-based counterparts, this material boasts strong thermal and chemical stability. More importantly, its bandgap can be finely tuned down to 1.26 eV with less than 2% calcium doping, placing it squarely within the Shockley-Queisser limit for optimal photovoltaic conversion.<\/p>\n<p>For the first time, my research team at the Autonomous University of Quer\u00e9taro explored an innovative idea of pairing (Ca, Ba)ZrS<sub>3<\/sub> with next-generation inorganic spinel hole transport layers (HTLs).
