Abstract The bonding of atoms is described as function of the electrostatic forces, covalent bonding, mixed bonding van der Waals bonding hydrogen and metallic bonding, and Born repulsion, yielding equilibrium distance and ionic or atomic radii that are tabulated. Repulsive potential softness parameters and Mohs hardness are tabulated Close packing of ions/atoms determine ordering preferences. Compressibility and Madelung constants, lattice constants and bond length are discussed and tabulated (Table 1.2). Electronegativity, ionicity and effective charges for numerous AB-compounds are listed. Atomic electron density profiles are given.
The bonding of atoms in semiconductors has primary influence of forming the lattice of any solar cell and is accomplished by electrostatic forces and by t...Read More
Based on my experience I have selected the parts of basic science that were helpful to my own research of solar cells, specifically on CdS based thin-film cells. As any, even somewhat more comprehensive treatises, a selection was made to include, beyond basic material science and the description of space charge effects, mostly CdS/Cu2S and CdS/CdTe solar cells. These treatments are more comprehensive, including most recent references. The descriptions are excellent examples for the theoretical analysis of most other thin-film solar cells. The other thin-film solar cells, the CIS-group and amorphous Silicon are discussed in three shorter chapters at the end of this book.
Overall the book is structured to address most aspects of thin-film solar cells, starting from the history of their devel...Read More
It is an honour to have been asked to prepare this short foreword for Karl Wolfgang Boer’s new “Handbook of the Physics of Thin-Film Solar Cells”. I first met Karl back in 1976 when I visited “Solar One", the first solar powered house that Karl proposed back in 1972. On the same day, I also visited the Institute of Energy Conversion, also founded by Karl at the University of Delaware in 1972. The early work of the Institute focussed on copper sulphide/cadmium sulphide (Cu2S/CdS) thin-film solar cells, the most promising thin-film cells of that era. Karl also served at that time as Chairman of Solar Energy Systems (SES) Inc. formed to commercialise these thin-film cells in conjunction with Shell Oil...Read More
