Structure and photovoltaic activity of cupric oxide-based thin film solar cells

ZnO Transparent conductive oxide for thin film silicon solar cells

There is general agreement that the future production of electric energy has to be renewable and sustainable in the long term. Photovoltaic (PV) is booming with more than 7GW produced in 2008 and will therefore play an important role in the future electricity supply mix. Currently, crystalline silicon (c-Si) dominates the market with a share of about 90%. Reducing the cost per watt peak and ene...

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

Zinc Oxide Sputter Deposition and Modeling of Copper Indium Gallium-diselenide-based Thin Film Solar Cells

3 To my beloved parents and family 4 ACKNOWLEDGMENTS Dr. Crisalle is the chair of my supervisory committee and I express my sincere appreciation for his guidance and constant encouragement through the last five years. I am also obliged to thank Dr. Hoflund, Dr. Svoronos and Dr. Eisenstadt for their valuable discussions and serving as my research committee members. Of course my gratitude should ...

Admittance spectroscopy of thin film solar cells

A short overview on thin film solar cells is given, and the complexity of their electronic structure is illustrated. Several physical mechanisms that give rise to a decay of the capacitance from a low-frequency value CLF to a high-frequency value CHF are discussed. A key of interpreting features in measured admittance spectroscopy (AS) spectra is a careful analysis of CLF and CHF and the temper...
