[交流] Comprehensive Interface Engineering Based on……Perovskite Solar Cells

Comprehensive Interface Engineering Based on Target Anchoring Agents towards Efficient and Stable Inverted Perovskite Solar Cells

Abstract：

Abstract Two pervasive challenges encountered in inverted perovskite solar cells (PSCs) are difficulties of depositing high-quality and reproducible perovskite thin films and unstatisfactory device stability in the ambient air. One constraint is the poor surface wettability of buried hole transport materials (HTMs) such as poly(triarylamine) (PTAA), which induces weak layer contact and impedes interfacial charge extraction. Antoher is impurity-induced surface defects of the perovskite layer pose a significant threat to the stability and reproducibility of PSCs. To tackle these issues, we propose a strategy that introduces amine molecule 4,4′,4″-tris(3-methyl phenyl phenylamino)triphenylamine (m-MTDATA) into the PTAA/perovskite interface, as a target modification to enhance the wettability of PTAA. The PTAA/m-MTDATA bilayer is also found to align energy levels of HTMs. Furthermore, phenyl ammonium bromide (PhABr) is deposited onto perovskite surface to remove excessive residual PbI2 for reduction of undercoordinate Pb2+ and iodide vacancies. The target device with m-MTDATA and PhABr achieves an impressive champion efficiency of 22.56% with negligible hysteresis, significantly higher than the pristine device (19.69%). Moreover, the related device also shows significantly enhanced resistance of moisture attack, thermal stress and continous light illumination. The strategy of target anchoring agents is feasible for high-performance inverted PSCs with enhanced stability.
