Inorganic perovskite solar cell based on tetraphenyl-porphine zinc interlayer achieves 82% fill factor
An international research team has proposed a perovskite solar cell architecture incorporating a thin tetraphenyl-porphine zinc interfacial layer to enhance surface potential, passivate defect states, and improve charge transport. The strategy leads to improved device efficiency and operational stability, enabling power conversion efficiencies exceeding 13%.
Australian researchers develop vapour-based manufacturing process for lead-free perovskite solar
Researchers at the University of Queensland have developed a scalable, lead-free perovskite solar cell manufacturing process that achieves record indoor-light efficiency while avoiding toxic materials and enabling flexible consumer electronics applications.
Scientists discover why lead-halide solar perovskites work efficiently despite being structurally ‘messy’
Researchers in Austria found that unusually high photovoltaic efficiency in lead-halide perovskites can be explained by internal electric fields generated at strain-induced domain walls, which separate charge carriers and enable long-range transport. Their experiments indicated that these effects arise from mesoscopic structural inhomogeneities rather than a uniform crystal structure, providing a general mechanism for charge separation in these materials.
