Abstract: Provided are a photoelectrode for hydrogen generation in solar water splitting and a manufacturing method thereof. The photoelectrode for hydrogen generation in solar water splitting, includes a light absorbing layer including a chalcopyrite compound; and a hydrogen generation catalyst including CuxS (where 0≤x≤2) which is present on the light absorbing layer, and may be manufactured by using a solution process which enables mass production and produce hydrogen from water using sunlight with high efficiency without using a noble metal element.
