Project title: Silicon nanocrystals solar cells ... Properties and characterisation
01.10.2009 - 30.09.2011

The main objective of this project is to investigate properties of the advanced solar cell materials for such solar cells, so called "nano solar cells". In this project we have available three growth techniques which will be used for sample preparation. Although silicon nanocrystals have been studied extensively in the past few years, this research is mainly focus on the structural properties of the silicon nanocrystals embedded in an oxide matrix. The samples will be characterized with electrical and optical methods. Capacitance technique such as Laplace Deep Level Transient Spectroscopy (Laplace DLTS) will be used for the very first time for studying the electrical properties of the silicon nanocrystals in the oxide matrix. The information that could be obtained with this technique, regarding the electrical behavior of the silicon nanocrystals such as free carrier concentration, deep trap states, activation energies etc., are of the crucial importance for the application of silicon nanocrystals in future generations of solar cells. With this we can assist the development of the Croatia's solar industry. This project will also provide the opportunity for transfer of knowledge to undergraduate students working on their diploma thesis.
