Growth of 2D halide perovskites for improved solar cell stability
Project motivation: 2D halide perovskites have emerged as a new class of two-dimensional materials with promising optoelectronic properties, long-term stability under environmental conditions, also potentially offering unlimited heterostructure configurations for exploration (Ref. Smith, M. D., et al. (2019). Chemical Reviews, 119(5), 3104-3139). However, tuning of their fabrication and implementation in solar cells present several challenges.
Project goal: Explore the synthesis and film growth of 2D halide perovskites, phenethylammonium lead iodide - (PEA)2PbI4 using a suitable solution method and comparing them to vapor-deposited grown films.
Tasks of MSc student:
Employ suitable solution-based method to grow 2D halide perovskites and analyze the spin-coated thin films using X-Ray Diffraction (XRD), Photoluminescent (PL), and Atomic Force Microscopy (AFM). Also, characterize and analyze PLD grown films and compare these films grow by different methodology. Application in baseline perovskite solar cell devices to improve their stability is also foreseen.
