    摘要： A photosynthesis apparatus includes a groove part formed in a semiconductor substrate; a first conductive type area formed on one side surface of the groove part; a second conductive type area formed on another side surface of the groove part; an oxidation electrode formed in contact with the first conductive type area on the one side surface; a reduction electrode formed in contact with the second conductive type area on the other side surface; and a proton diaphragm formed at a center part of the groove part. Water including carbon dioxide is supplied to the groove part, and light is radiated to the oxidation electrode or the reduction electrode to generate oxygen and a hydrogen ion from the water at the oxidation electrode, and the generated hydrogen ion penetrates the proton diaphragm and reacts with the carbon dioxide to generate formic acid at the reduction electrode.

    摘要： Provided is an artificial-photosynthesis array configured of artificial-photosynthesis modules which have been arranged in one or more rows and which receive light and decompose a supplied aqueous electrolyte solution to thereby obtain hydrogen gas and oxygen gas. The artificial-photosynthesis modules each includes an electrolytic chamber for hydrogen where hydrogen gas is generated and an electrolytic chamber for oxygen where oxygen gas is generated, the chambers being isolated from each other. The electrolytic chambers for hydrogen and electrolytic chambers for oxygen of the artificial-photosynthesis modules are alternately connected so that the electrolytic chamber for hydrogen of each artificial-photosynthesis module is connected to the electrolytic chamber for oxygen of another module and the electrolytic chamber for oxygen of each artificial-photosynthesis module is connected to the electrolytic chamber for hydrogen of another module.

    摘要： Important components of direct solar based nanowire enabled chemical processing and electrochemical systems are a high efficiency and highly stable photocathode and 2-photon dual electrodes. The former enables photo-excited electrons that lead to hydrogen generation whereas the later with complementary energy bandgap photoanode and photocathode enables high efficiency, unassisted solar-driven water splitting. Accordingly, it would be beneficial to leverage the high surface areas and self-contained conversion of direct solar illuminated hydrogen generation from such nanowires with multiple junctions for broad solar spectrum absorption by providing monolithically integrated multi-junction photocathodes. It would be further beneficial to provide nanowire based dual-photoelectrode systems that together with a parallel illumination scheme, can fundamentally address these critical challenges. It would be further beneficial for these nanowire based dual-photoelectrode systems to exploit a semiconductor material family that can be tuned across the solar spectrum, can be doped both p-type and n-type and supported large current conduction.

    摘要翻译： 直接太阳能纳米线化学处理和电化学系统的重要组成部分是高效率和高度稳定的光电阴极和双光子双电极。 前者能够产生导致氢气产生的光激发电子，而后者具有互补能带隙光电阳极和光电阴极，可以实现高效率，无助太阳能驱动的水分解。 因此，通过提供单片集成的多结光电阴极，利用具有多个连接点的这种纳米线的高表面积和直接太阳能照射氢生成的独立转换是有利的。 提供基于纳米线的双光电子系统将是更有利的，其与平行照明方案一起可以从根本上解决这些关键挑战。 对于这些基于纳米线的双光电子系统来说，利用可以在太阳能光谱上调谐的半导体材料族将是更有益的，可掺杂p型和n型并支持大电流传导。
