You may want to check the Australian National University (ANU) website as they very active in solar energy research area.

Also, you can check the National Renewable Energy Laboratory (NREL.gov) website and Sandia National Laboratory (SNL.gov) website. Both NREL and SNL are active in this area.

Hope you find this information helpful and good luck.

Dear Yiwei Fu, and Yehia F. Khalil,

The solar power tower, known as 'central tower' power plants or 'heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target). Concentrated solar thermal is seen as one viable solution for renewable, pollution-free energy.

Concentrating solar power towers:

Top: Solar towers of the Ivanpah facility, the world's largest solar thermal power station in the Mojave Desert, southeastern California

Middle: PS10, the world's first commercial solar power tower in Andalusia, Spain

Bottom: The THEMIS solar power tower in the Eastern Pyrenees, France (left) and the German experimental Jülich tower (right)

Early designs used these focused rays to heat water, and used the resulting steam to power a turbine. Newer designs using liquid sodium have been demonstrated, and systems using molten salts (40% potassium nitrate, 60% sodium nitrate) as the working fluids are now in operation. These working fluids have high heat capacity, which can be used to store the energy before using it to boil water to drive turbines. These designs also allow power to be generated when the sun is not shining.

Hope you understand about it.

If any question feel free to to ask me.

Thanks.

I think you can find useful information on the NREL website: https://www.nrel.gov/solar/

The research area called: Concentrating Solar Power (CSP) technologies has good information in the Publications section...
