Photosynthetic organisms harvest solar energy by absorbing light and ultimately transferring energy through a cascade of chemical reactions to power all cellular processes. Core components initiating this reaction cascade are the photosynthetic reaction centres Photosystem I and Photosystem II.
This action is not available. Solar energy refers to heat or light energy from the sun. Solar energy is by far the most plentiful type of renewable energy, delivered to the surface of the Earth at a rate of 120,000 Terawatts (TW) per hour, compared to the global human use of 19.8 TW in the entire year of 2019.
In plants, some sugar molecules are stored as sucrose or starch. Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
This reaction takes place in an enzyme known as photosystem II, and the recent determination of its structure has given strong hints of how nature uses solar energy to generate hydrogen and oxygen from water.
In photosynthesis, solar energy is converted into energy rich products which are necessary to drive the biochemistry of life. In photosynthesis, excitation energy transfer and charge separation are two ultrafast processes with transfer rate of 1012 s −1 (Colbow and Dunyluk, 1976).
Man made silicon solar cells can convert only 18%–25% light into electricity, but plants nearly convert all absorbed light into chemical energy (Blankenship et al., 2011, Chen et al., 2015). Diverse sets of optical phenomenon by insects and plants can inspire us to design and develop the much improved solar cells.
