Small, Volume 22, Issue 3, 13 January 2026.Organic photodiodes are limited by dark current and excess low‐frequency noise. This review synthesizes mechanisms of noise, links to three leakage pathways, and unifies measurement practice with device design. By outlining energetics, morphology, and interface strategies, it provides validated routes to lower noise floors and higher detectivity across
