Characterization of CdxZn1-xS and PbS thin films for Photovoltaics
ISBN: 9783659414039 / Angielski / Miękka / 2013 / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A study of CdZnS and PbS nano-crystalline thin films deposited by chemical bath deposition (CBD) method has been made using Four point probe for electrical sheet resistivity, UV-Vis spectroscopy and solar simulator for optical and Photovoltaic cell properties respectively. Sheet resistivity for CdZnS thin films was found to decrease as the concentration of Zn increased while PbS thin films had their sheet resistivity increase with increase in bath concentrations. Optical band gap for CdZnS had a tunability depending on the various Zn2+ concentrations used successfully as demonstrated by...

Electrical and optical characterization of CdxZn1-xS and PbS thin films for photovoltaic applications: Thin film characterization for solar cells
ISBN: 9783656718390 / Angielski / Miękka / 2014 / 118 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Master's Thesis from the year 2011 in the subject Physics - Applied physics, grade: A, Kenyatta University, course: Master of Science ( Physics), language: English, abstract: In this research an n-type CdxZn1-xS and p-type PbS thin films were optimised for solar cell applications employing chemical bath deposition technique. The thin films were prepared using thiourea and nitrates of cadmium, zinc and lead. Deposition of optimised CdxZn1-xS was done by CBD at 820 C and in alkaline conditions while that of PbS was done at room temperature and both films at normal atmospheric pressure utilizing...

Physics of Thermal Phenomena
ISBN: 9783659517617 / Angielski / Miękka / 2014 / 672 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Thermodynamics is a macroscopic science concerned with properties such as pressure, temperature, chemical potential, and volume. Unlike quantum mechanics, thermodynamics is not based on a specific molecular model and therefore it is unexpected by our changing concepts of atoms and molecules. Indeed, the major foundations of thermodynamics were laid long before detailed atomic theories became available. On the negative side, equations derived from laws of thermodynamics do not provide us with a molecular interpretation of complex phenomena. Although thermodynamics helps us predict the...
