This paper reviews the impacts of employing inserts, nanofluids, and their combinations on the thermal performance of flat plate solar collectors. The present work outlines the new studies on this specific kind of solar collector. In particular, the influential factors upon operation of flat plate solar collectors with nanofluids are investigated. …
A novel ultra-high-temperature tower system was depicted in Fig. 1.This system consists of a collector, a thermal energy storage (TES) device, and a power cycle unit. Liquid tin was used as the heat transfer fluid to raise the outlet temperature (T out) of the collector to 1623 K, employing a Brayton cycle for power generation with an expected cycle efficiency …

There are basically two types of collectors, stationary and tracking [3] (Fig. 1).Different collector configurations can help to obtain a large range of temperature for example, 20–80 C is the operating temperature range of a flat plate collector (FPC) [4] and 50–200 C is for an evacuated tube solar collector (ETSC) [5], [6].
Considering the low heat dissipation due to the vacuum encapsulation around the absorber surface, if these collectors can be applied in the forced-circulation solar air heating system with high operation temperature, they will have a better performance than flat

A straight-through all-glass evacuated tube collector (ETC) made of high-quality borosilicate glass was developed for large-scale low and medium temperature solar hot water systems. It consists of an inner and outer tube without a free end and was shown to be mechanically stable with a thermal expansion coefficient of (3.3 ± 0.1) × 10 −6 K −1 .
Evacuated-tube solar collectors have better performance than flat-plate solar collectors, in particular for high-temperature operations [].
An evacuated tube solar collector is a type of solar thermal collector that improve flat plate collectors. Solar collectors aim to convert solar radiation into thermal energy reducing heat losses. The vacuum tube solar collector consists of a set of cylindrical tubes. The ...

However, they are used extensively in evacuated collectors, which utilise a partial vacuum, such as the receivers in high temperature solar thermal systems. Oxide coatings were the first type of coating used in solar collectors.
As another type of non-concentrating solar collector, the evacuated tube solar collector adopts a vacuum environment to inhibit thermal conduction and convection, thus its operating temperature is more suitable for steam generation.
