Solar　energy　is　an　important　renewable　energy　and　will　play　a　significant　role　in　future　global　electricity　production.　A　comprehensively　review　overview　of　linear　concentrated　solar　power　is　studied　which　is　a　unique　technique　that　includes　parabolic　trough　collector　and　linear　Fresnel　reflector.　Some　crucial　aspects　have　been　summarized　and　prospected　on　concentrating　system,　heat　collecting　system　and　heat　storage　system.　Research　on　concentrating　system　includes　the　mirror　field　of　parabolic　trough　collector,　primary　mirror　field　and　secondary　concentrators　of　linear　Fresnel　reflector.　Research　on　heat　collecting　system　includes　inner　collector　coating,　heat　transfer　fluid　and　enhanced　heat　transfer　technology.　Research　on　heat　storage　system　includes　heat　storage　molten　salt　and　storage　tank.　Lastly,　the　potential　research　directions　and　future　research　hotspots　of　these　technologies　are　prospected.　The　mirror　field　structure　should　be　optimized　the　distribution　of　surface　energy　flux　density　on　the　collector　tube　in　parabolic　trough　collector,　while　in　linear　Fresnel　reflector　improve　the　optical　efficiency.　Molten　salt　is　one　of　the　best　heat　transfer　fluid　for　high　temperature　power　generation　in　the　concentrated　solar　power　system.　Inserts,　fins　and　shaped　tubes　are　used　to　enhance　heat　transfer　for　collector.　Developing　molten　salt　with　a　wider　working　temperature　range　and　more　stable　physical　and　chemical　properties　is　a　hot　research　direction.　©　2025　Elsevier　B.V.
