Mimicking photosynthetic solar energy transduction.

Solar energy for electricity and fuels

Solar energy conversion into electricity by photovoltaic modules is now a mature technology. We discuss the need for materials and device developments using conventional silicon and other materials, pointing to the need to use scalable materials and to reduce the energy payback time. Storage of solar energy can be achieved using the energy of light to produce a fuel. We discuss how this can be ...

Photosynthetic reaction center as a quantum heat engine.

Two seemingly unrelated effects attributed to quantum coherence have been reported recently in natural and artificial light-harvesting systems. First, an enhanced solar cell efficiency was predicted and second, population oscillations were measured in photosynthetic antennae excited by sequences of coherent ultrashort laser pulses. Because both systems operate as quantum heat engines (QHEs) tha...

How photosynthetic bacteria harvest solar energy.

Carbon Metabolic Pathways in Phototrophic Bacteria and Their Broader Evolutionary Implications

Photosynthesis is the biological process that converts solar energy to biomass, bio-products, and biofuel. It is the only major natural solar energy storage mechanism on Earth. To satisfy the increased demand for sustainable energy sources and identify the mechanism of photosynthetic carbon assimilation, which is one of the bottlenecks in photosynthesis, it is essential to understand the proces...

C-based metabolomics and fluxomics

Photosynthesis is the process to convert solar energy to biomass and biofuels, which are the only major solar energy storage means on Earth. To satisfy the increased demand for sustainable energy sources, it is essential to understand the process of solar energy storage, that is, the carbon metabolism in photosynthetic organisms. It has been well-recognized that one bottleneck of photosynthesis...
