High\u2010entropy TMDs, in which local lattice distortion and charge redistribution occur within a van der Waals layered structure, are expected to overcome these intrinsic limitations by improving catalytic activity, photocarrier dynamics, and phase stability. Here, we demonstrate a wafer\u2010scale 2D high\u2010entropy (MoWTaNbRu)S\n                    <jats:sub>2<\/jats:sub>\n                    thin\u2010film catalyst with distorted 1T phase on\n                    <jats:italic>p<\/jats:italic>\n                    \u2010Si photocathode for PEC\u2010HER.

PEC kinetic analyses, including intensity\u2010modulated photocurrent spectroscopy, demonstrate that (MoWTaNbRu)S\n                    <jats:sub>2<\/jats:sub>\n                    markedly suppresses the recombination of photogenerated charge carriers, enabling more efficient charge extraction and accelerated interfacial reaction kinetics. Furthermore, the high\u2010entropy\u2010driven stabilization of the metastable 1T phase ensures excellent durability of the photocathode. As a result, the (MoWTaNbRu)S\n                    <jats:sub>2<\/jats:sub>\n                    \/TiO\n                    <jats:sub>2<\/jats:sub>\n                    \/\n                    <jats:italic>p<\/jats:italic>\n                    \u2010Si photocathode shows a remarkable photocurrent density and stability for over 100\u00a0h, outperforming single\u2010metal TMDs. This study demonstrates how configurational entropy enhances catalytic activity, photocarrier transport, and phase stability of TMDs, establishing a general design principle for next\u2010generation
