A high‐performance parallel tandem solar cell employing ultra‐thin Ag as the intermediate anode is demonstrated, which comprises a semitransparent front sub‐cell and a microcavity assisted back sub‐cell. In addition to the extended optical field as a result of the tandem architecture, the prominent...
