As a thermal energy generating power station, CSP has more in common with thermal power stations such as coal, gas, or geothermal. A CSP plant can incorporate thermal energy storage, which stores energy either in the form of sensible heat or as latent heat (for example, using molten salt), which enables these plants to continue supplying electricity whenever it is needed, day or night.

An example of a Low Concentration PV Cell's surface, showing the glass lensing. Low concentration PV are systems with a solar concentration of 2–100 suns. [37] For economic reasons, conventional or modified silicon solar cells are typically used. The heat flux is typically low enough that the cells do not need to be actively cooled.
Acceptance angle. The "acceptance angle" figure illustrates this concept. The concentrator is a lens with a receiver R.The left section of the figure shows a set of parallel rays incident on the concentrator at an angle α < θ to the optical axis.
According to the authors, this ratio is well approximated by ln(fQ s /Q c), where f is the combination of factors f s f ω t s /(2t c), in which f ω is the solid angle of the sun divided by π. The maximum value of f without light concentration (with reflectors for example) is just f ω /2, or 1.09 × 10 −5, according to the authors.
Thanks to these devices, light arriving on a large surface can be concentrated on a smaller cell. The intensity concentration ratio (or "suns") is the average intensity of the focused light divided by 1 kW/m 2 (reasonable value related to solar constant). If its value is X then the MJ current becomes X higher under concentrated illumination ...
A luminescent solar concentrator. A luminescent solar concentrator (LSC) is a device for concentrating radiation, solar radiation in particular, to produce electricity. . Luminescent solar concentrators operate on the principle of collecting radiation over a large area, converting it by luminescence (specifically by fluorescence) and directing the generated radiation into relatively small ...
A parabolic trough is made of a number of solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length up to 15 metres (49 ft 3 in) or more. About a dozen or more of SCM make each SCA up to 200 metres (656 ft 2 in) length. Each SCA is an independently-tracking parabolic trough. [9]
A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solid solution on glass or plastic backing, along with electrodes on the front and back to collect current.
