The Way

The relatively new technique of quantum-dots sensitizing the solar cells for optimum cost-efficiency of photovoltaics is reviewed while launching new concept of bonding-quantum dots – the so called bondots (abbreviated as D), founded on the Dirac quantum theory of coupling spinors, while the associated analytics and basic illustration on paradigmatic chemical bonds are revealed, so paving the way for experimentally searching of at least doubling the photo-electric conversion in sustainable bondotic sensitized solar cells.

Chemical Combination

A material irradiated with electrons emits x-rays having energies characteristic of the elements present. Chemical combination between elements results in a small shift of the peak energies of these characteristic x-rays because chemical bonds between different elements have different energies. The energy differences of the characteristic x-rays resulting from valence electron transitions can be used to identify the chemical species present and to obtain information about the chemical bond itself. Although these peak-energy shifts have been well known for a number of years, their use for chemical-species identification in small volumes of material was not realized until the development of the electron microprobe.
