abstract = "Semi-artificial photosynthetic systems have opened up new avenues for harvesting solar energy using natural photosynthetic materials in combination with synthetic components. This chapter describes a recently reported semi-artificial system for solar energy conversion that synergistically combines photoreactions in a purple-bacterial photosynthetic membrane with those in three types of transition metal-semiconductor Schottky junctions. A transparent film of a common transition metal interfaced with an n-doped silicon semiconductor exhibited an in-plane potential gradient when a light-penetration variance was established on its surface by optical shading of photo-absorbing photosynthetic membranes. The In-plane potential gradients (0.08–0.3 V) enabled a directional charge transport between the synthetic and natural photo-electric systems, which was further enhanced in a device setting by a biocompatible thixotropic gel electrolyte that permeated the membrane multilayer, driving a strong and steady photoelectric current as high as 1.3 mA cm−2, the highest achieved so far with any anoxygenic photosynthetic system.",
