The metal‐semiconductor contact plays an important role to define the performance of a device where current extraction is critical. In that regard, Mink et al. (pp. 551–554 ) examined a set of metals (Al, Ti, Co) fabricated as Ohmic and Schottky contact to study which can enable better performance in micro‐sized microbial fuel cells fabricated on silicon. The study shows that, in general AlSi x (Ohmic contacts) provide higher current density whereas CoSi 2 Ohmic contacts provide higher power density.
