Vidareutveckling av PV/T-receiver för koncentrerat solljus
The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media. The electricity is supplied to the local grid and the heat is supplied to a local heating system. In this master thesis, the author has developed a number of tests for the Absolicon X10 with the superior goal to enhance the quality and electrical performance. The main areas of interest were:The ribbon connecting the solar cellsThe correlation between indoor and outdoor performanceHow the position of the receiver in the trough affects the electrical outputA test method for evaluation of ribbons was developed and was applied to a new type of ribbon. The method showed that this new type of ribbon was not good enough for implementation in the production chain. Two types of indoor testing methods were developed, with the aim of determine the electrical performance of receivers. Both methods were unable to do so, but one of them might be good enough with some improvements. A position of the receiver which gives higher electrical output and higher tolerance for the tilt angle of the through was found.
