Modeling, synthesis, and characterization of thin film copper oxide for solar cells

The modeling, growth, and characterization of Copper Oxide thin films for solar cell applications are reported. Cu_2O has several attractive properties which include its direct band gap (Eg=2.17 eV) for use in photoelectrolysis of water and use in tandem multi-junction cells. Detailed balance calculations predict efficiencies on the order of 20% while Cu_2O cells have yet to even pass 2% efficiency. The device physics model reveals that defects, particularly at the heterojunction interface, are the main reason for lowered efficiencies. Epitaxial Cu_2O (100) thin films on MgO are fabricated using RF Oxygen plasma MBE. The films are quite smooth and showed mobilites in the range of 10-100 cm^2/V*sec and carrier concentrations in the range of 10^(14)-10^(17). Finally, the epitaxial growth of Cu_2O on a MgO template is demonstrated

Note on the first recorded audit in the Bible

According to an early commentary on the Bible, Joseph is the first auditor of accounting records in the Bible

History of LIFO

The history of LIFO illustrates the interplay of taxes and the general acceptance of accounting principles. In this paper, the gradual acceptance of LIFO in the United States is traced. The study focuses on both the theoretical evolution of LIFO and its acceptance by taxing authorities and accountants

Accounting measurement and capacity limits of technological devices

In this paper the capacity limits of technological devices used in ancient Egypt are used to explain the Biblical phrase that in accounting for grain the Egyptians ran out of numbers
