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

Solar thermal is another way to use solar energy to generate power. Many attempts to establish solar (solo) thermal power stations have been practiced all over the world. Although there are some advantages in solo solar thermal power systems, the efficiencies and costs of these systems are not so attractive.
Heating, hot water and thermal power generation are the more common ways of solar energy thermal utilization in EU [13, 14]. At present, the solar water heater is the common way in China.

The generator can produce, as a proof of concept, a power output of up to 0.1 nW (power output per unit volume up to 1.3 W m −3 ). Our results demonstrate that such a molecular thermal power generation system has a high potential to store and transfer solar power into electricity and is thus potentially independent of geographical restrictions.
There is an urgent need for alternative compact technologies that can derive and store energy from the sun, especially the large amount of solar heat that is not effectively used for power generation.
