Intrinsic defects and metastability effects in Cu 2O. Citing article.

The optical properties of sputtered Cu2O thin films doped with the nitrogen concentrations between 1 and . at% have been investigated by spectrophotometric measurements. All the doped samples exhibit two clearly defined absorption bands at energies below the gap, with an intensity well correlated with the N concentration. Intrinsic defects and metastability effects in Cu 2O.

The thesis deals with the study of the defects and doping of cuprous oxide (Cu2O) a very long studied semiconductor. The interest in Cu2O is due to its optical properties, its low cost and low toxicity which make it a perfect candidate for low cost photovoltaic cells.

Claudia Malerba, Francesco Biccari, Cristy Leonor Azanza Ricardo, Mirco D’incau, P Scardi, Alberto Mittiga. The optical absorption coefficient of thin film and bulk Cu2O at room temperature is obtained from an accurate analysis of their transmittance and reflectance spectra.

Defects and Doping in Cu2O. Presently the interest in Cu2O as photovoltaic material has increased again because of the good results obtained from materials which have analogous problems, both under the physical and technological aspects. These materials are CuInSe2 (CIS), CuGaSe2 (CGS) and the intermediate alloys Cu(In, Ga)Se2 (CIGS), which now can give a photovoltaic conversion eciency up to 20%. The presence of an element like indium, rare and expensive, in these compounds shed a negative light on the future of these semiconductors.

Survey of doping in Cu2O. Looking at the literature on doping of Cu2O thin lms, it is often concluded that the doping of Cu2O is a feasible task.

This book is the Francesco Biccari's PhD thesis in physics, defended at the Sapienza - University of Rome in February 2010. The thesis deals with the study of the defects and doping of cuprous oxide (Cu2O) a very long studied semiconductor. The interest in Cu2O is due to its optical properties, its low cost and low toxicity which make it a perfect candidate for low cost photovoltaic cells.
