The beneficial role of marcasite in pyrite thin films for photoelectrochemical applications is reported by J. P. Hofmann and co‐workers on page 9602. A bulk heterojunction with staggered band alignment at the pyrite–marcasite interface enhances charge‐carrier separation and leads to a dramatic increase of photocurrent in the FeS 2 films.
