NOVELTY - The fixture has a first fixing body (2) with a first notch (21) that is wide at the top and narrow at the bottom, and a second fixing body (3) disposed on one side of first fixing body and with a second notch (31) that is wide at the top and narrow at the bottom and is connected to the first notch of first fixing body. A sleeve (4) is arranged around the first and second fixing bodies for holding and fixing the first and second fixing bodies. The first and second notches are connected to form a space used for receiving a homogenizer (5).    USE - Fixture for attaching homogenizer of concentrator solar receiver.    ADVANTAGE - Ensures stable fixing of the concentrator solar receiver on the first slot since size of the insulating substrate is the same with the size of first slot. Improves operation quality of the concentrator solar receiver. Prevents possible breakage or damages to the structure of concentrator solar receiver during the adhesion process and ensures stability of the homogenizer. The homogenizer has less adhesive failure and better adhesion quality by using fixture for attaching homogenizer of concentrator solar receiver. Ensures longer service life of the homogenizer and increases assembling efficiency since inverted cone-shaped homogenizer works stably in combination with the sun tracking system without collapsing easily. Reduces labor and time required for complete attachment of the homogenizer. The adhesive-overflow problem caused by over-push of the homogenizer is minimized by eliminating need to apply any force to the homogenizer since homogenizer drops down naturally to be adhered with adhesive due to gravity. The distance between homogenizer and solar cell is controlled precisely since drop distance of the homogenizer within adhesive is the same. Improves adhesion efficiency and increases performance and service life of the product since shortcomings of attaching the homogenizer manually are eliminated by connecting the second notch of second fixing body to the first notch of first fixing body to form a space.
