p‐Type conjugated polyelectrolytes (CPEs) are developed as organic‐based work‐function‐modifier materials for the broad work‐function (WF) tunability of various metal electrodes. Facile oxidative treatments of n‐type CPEs using various oxidants produce unprecedented p‐type CPEs with reversed electronic properties corresponding to n‐type CPEs, resulting in fine WF tuning of adjacent metal electrodes. This change leads to substantial increases in power conversion efficiency and lifetime of organic solar cells.
