    Hi everyone,

    My name is Michael Kolawole, second-year PhD student researching metal oxides to improve PV cell efficiency. I am interested in PV, solar cell, and renewable energy research, as well as attending related conferences.

    Hi Michael
    There are several different roles that metal oxides can play in solar cells as you probably know. The biggest challenge is finding ones that match the band alignment and have very high transparency but low resistivity while being chemically compatible with the rest of the device stack.  I did a lot of research into SnO2:F, ZnO:B, ZnO:Al and especially ITO in the 80s and 90s for thin film PV cells. Now there are more exotic metal oxides for perovskite and Si heterojunctions (MoOx, IZO) but I don't know much about them. Feel free to reach out if you have questions about the legacy MO's.
