The thermal collector for Al 2 O 3 fluid is located below and attached to the PV solar cell, resulting in the contour being similar to the PV contour in shape and color. In contrast to the basic collector model, the direct flow collector system produces a thermal fluid. The fluid produced in Al 2 O 3 in the cooling system reached 307.97 K.
A solar cell is made of semiconducting materials, such as silicon, that have been fabricated into a p–n junction. Such junctions are made by doping one side of the device p-type and the other n-type, for example in the case of silicon by introducing small concentrations of boron or phosphorus respectively.
