He has worked in various colleges and universities as instructor. He joined Dr. Do Young Kim’s research group in the spring of 2020 and he is working on halide perovskite solar cells.  The focus of his research is on the fabrication and characterization of low-cost, highly efficient, and stable perovskite solar cells (PSCs). Halide perovskite is an emerging semiconductor material applicable for low-cost thin-film photovoltaic technology. The great attention given to the use of perovskite absorber in solar cells is attributed to their tunable bandgap, large absorption coefficient, high carrier mobility, and low-temperature solution processability. The major drawback of PSCs relates to the issue of low stability under ambient environment of humidity, heat, light and oxygen.

 

For his research Matthew is exploring a combination of strategies including compositional engineering, surface passivation and antioxidant additive for improving the stability and performance of PSCs. Matthew is also addressing barriers to commercialization of hybrid organic-inorganic perovskite solar cell which is mainly the potential environmental impacts related to the lead-based perovskite absorber. He is working on various lead-free materials for perovskite absorber to mitigate, and potentially eliminate toxicity and environmental concerns. He enjoys generous funding and facilities that allow him to conduct cutting-edge research. One of which is an important aspect of his research that concerns the application of perovskite solar cells for radiation hardened electronics and space exploration as a part of NASA EPSCoR program. He has participated in other interesting projects including metal halide semiconductors for light emitting diodes (LEDs) and hybrid organic-inorganic perovskite photodetectors.

 

Matthew is also involved in a National Science Foundation innovation corps (NSF I-Corps) grant program where his team is working on commercialization of innovative infrared driven OLED projection display technology. In addition to his educational achievements and conducting research at the Helmerich Research Center (HRC) on the OSU Tulsa campus, Matthew serves as Vice President of International Student Ministries (ISM), a faith-based organization catering to the needs of students in the Tulsa area. Matthew is grateful for support from faculty and students at the HRC. He is passionate and hopes to pursue a career in industry focusing on semiconductor, electronics, and renewable energy after completing his PhD.
