Efficient solar thermal energy harvesting and storage are critical steps toward utilizing the abundant solar irradiation that reaches the surface of the earth. Current solar thermal approaches rely on costly high optical concentration systems, leading to high heat losses by hot bulk materials and surfaces Solar photovoltaic energy conversion: Converting sunlight directly into electricity. When light is absorbed by matter, photons are given up to excite electrons to higher energy states within the material (the energy differencebetween the initial and final states is given by hν). Particularly, this occurs when the energy Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use Solar thermal power plants are electricity generation plants that utilize energy from the Sun to heat a fluid to a high temperature.This fluid then transfers its heat to water, which then becomes superheated steam.This steam is then used to turn turbines in a power plant, and this mechanical energy is converted into electricity by a generator.This type of generation is essentially the same as.
