Munch, Jesper Hamilton, Murray Wayne Ebendorff-Heidepriem, Heike Naeem, Muddassar School of Chemistry and Physics 2015 http://hdl.handle.net/2440/95229 Improving the efficiency of solar cells is an active area of research in photovoltaic industry. The research work presented in this dissertation is based on a quest for better and improved silicon solar cells. The current work aims to explore different possibilities by studying advance approaches for PV applications. Additionally this work is intended to seek the feasibility of new photonic concepts for improving silicon solar cells. In this work we have investigated solar downconverters consisting of tellurite glass. Their fabrication process is discussed followed by the experimental characterization. Optical measurements such as absorption spectra, fluorescence spectra and fluorescence quantum efficiency are undertaken. These optical measurements enabled to understand physical processes associated with the materials used. Furthermore, the work presented in the thesis is focused on the realization of a downconverter. The work can be roughly sub-divided into two parts. One part identifies the suitable energy conversion materials and the second part deals with the development and demonstration of the experimental method for characterizing a downconverter. The final part of the work extends investigation for more efficient materials prior to their use at the practical level. We also propose an architectural design for the efficient use of a downconverter with a silicon solar cell.
