ABSTRACT
This chapter provides an interdisciplinary understanding of renewable energy and proposal of solutions. Photosynthesis can roughly be divided into a photochemical reaction that converts light energy into chemical energy and a Calvin circuit that synthesizes sugar from chemical energy. Artificial photosynthesis is a technology that literally carries out artificial photosynthesis. Photosynthesis in the natural world synthesizes carbohydrates as chemical energy from water and carbon dioxide and light energy such as sunlight, but artificial photosynthesis, in a broad sense, may include solar cells. It has been discovered that strontium titanate doped with rhodium is a photocatalyst that reduces water by irradiating visible light to generate hydrogen, and it has also been found that by combining with bismuth vanadate that generates oxygen with visible light, successfully decomposed. A solar cell is a power device that converts light energy into electric power utilizing the photovoltaic effect.
