Energy Conversion in Photosynthesis: ..

N2 - Photosynthesis is the source of our food and fiber. Increasing world population, economic development, and diminishing land resources forecast that a doubling of productivity is critical in meeting agricultural demand before the end of this century. A starting point for evaluating the global potential to meet this goal is establishing the maximum efficiency of photosynthetic solar energy conversion. The potential efficiency of each step of the photosynthetic process from light capture to carbohydrate synthesis is examined. This reveals the maximum conversion efficiency of solar energy to biomass is 4.6% for C3 photosynthesis at 30 °C and today's 380 ppm atmospheric [CO2], but 6% for C4 photosynthesis. This advantage over C3 will disappear as atmospheric [CO2] nears 700 ppm.

Photosynthesis: The Final Frontier Improving yields through plants' conversion efficiency

and mechanistic details of energy conversion in photosynthesis is ..

Formate is produced at indium and lead electrodes at a conversion efficiency of 48 mg of CO2/kilojoule of energy input.

The problem is that lighting designers and horticulturalists generally do not speak the same language. Whereas we speak in terms of lumens and illuminance, horticulturalists speak in terms of photosynthetically active radiation (PAR) and photosynthetic photon flux density (PPFD). Ask for an explanation of these terms and you will hear talk of micromoles, and possibly microeinsteins, of photons. Instead of luminous flux, there is quantum flux. It can be very confusing, not to say frustrating.

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to stripelectrons from suitable substances such as water, producing oxygen gas.

of solar energy conversion in photosynthesis: ..

Toshiba Corporation today announced the development of a new technology that uses solar energy, the power of the sun, to generate carbon compounds from carbon dioxide and water, and to deliver a viable chemical feedstock or fuel with potential for use in industry. Toshiba introduced the technology at the 2014 International Conference on Artificial Photosynthesis (ICARP2014) on 26 November, at the Awaji Yumebutai International Conference Center in Japan.

Photosynthesis is the process used by plants to convert electromagnetic radiation – light – into chemical energy that is used for growth and development. All that is needed for this process is carbon dioxide (CO2), nutrients, and water. The process itself is not particularly efficient; only 4 to 6 percent of the absorbed radiation is converted into chemical energy (Zhu et al. 2010, Table 2). Still, it is the engine that drives most life on this planet.

Quantum efficiency of photosynthetic energy conversion.

AB - Photosynthesis is the source of our food and fiber. Increasing world population, economic development, and diminishing land resources forecast that a doubling of productivity is critical in meeting agricultural demand before the end of this century.

This advantage over C3 will disappear as atmospheric [CO2] nears 700 ppm.

The energy conversion efficiency of the Calvin cycle is ..

Atmospheric concentrations of carbon dioxide, widely understood to be a major cause of global warming(Note 1), continue to increase. There are also concerns about the exhaustion of fossil fuels, which are spurring interest in adoption of renewable energy sources(Note 2). Artificial photosynthesis technologies that use solar energy to generate carbon compounds from carbon dioxide and water are seen as promising means to resolve both issues.

Efficiency - Artificial Photosynthesis

Toshiba has developed an artificial photosynthesis technology that converts energy into carbon compounds from carbon dioxide at an efficiency of 1.5%, the highest level yet recorded(Note 3). Sunlight converts the carbon dioxide and water into carbon monoxide, a source for production of methanol, which can be used as a substitute for gasoline and as a feedstock in the manufacture of diverse products, including adhesives, medicines and PET bottles.

Energy conversion efficiency in The Azimuth Project

Other artificial photosynthesis technologies use materials that absorb UV light from sunlight to reach the high reaction energy required to convert carbon dioxide into a fuel. However, their low level of light utilization efficiency drags down the energy conversion efficiency, and practical application requires increased efficiency.

Artificial Photosynthesis: Saving Solar Energy for a …

The electrolyte type, pH, electrocatalyst type, and cell voltage were found to have a strong effect on the efficiency of conversion of carbon dioxide to formate.

For efficient energy, do you want solar panels or biofuels?

A common unit of measurement for PAR is photosynthetic photon flux density (PPFD), measured in units of moles per square meter per second. In this case, every absorbed photon, regardless of its wavelength (and hence energy), is assumed to contribute equally to the photosynthetic process. This is in accordance with the , which states that every photon (or quantum) that is absorbed will excite one electron, regardless of the photon’s energy, between 400 nm and 700 nm. For this reason, photosynthetic photon flux is also referred to as quantum flux.
