The purpose of this thesis to conduct a research study on manufacturing cones and squared Q-Faberge with reflecting hard paper material with reflectivity approximately 85%, which can have even light distribution at the exit aperture. For the constructions of certain Faberge cones I calculated the specific Faberge curve with the help of mathematical expressions and finally find the equation and draw it on maple computer software. As I was a part of a research group of SERC for TPV so the part of project, I was supposed to do, was to construct cones and squared Quasi-Faberge and check their performance with the help of spectrophotometer and compare the results with previous calculated results of square cornet made with flat mirrors. It must be noted that normal circular curved cones CPC cones which have uneven light distribution and cause hot spot at the exit aperture. Measurements and calculations on silver coated and aluminium coated cones indicated that arrangements with cones having a TPV cell at the exit aperture are technically worthwhile. The concentration depends on the geometry of the cone and the reflector material of the surface. The low cost, compared to PV cells of polished and coated 0.7 mm aluminium makes it probably that the use of cone concentrators would reduce the cost per produced kWh. Factors to take account are higher labour and material costs for manufacturing models.
