“…The data sets for CdTe polycrystalline and single crystalline materials agree well with each other except for the data of Loferski [35]. As the absorption coefficient a for CdTe is higher than 10 6 m À 1 above the absorption edge, most of the incident light will be absorbed within 1 mm depth or less.…”

“…It was necessary to wait 10 years in order to develop epitaxial growth techniques that were able to produce a small solar cell showing an efficiency of 13% [18], which is quite low compared to the theoretical efficiency of 26% [19]. It was already known [20] that the direct recombination process, occurring in poor-quality GaAs crystals, limits the cell output. Moreover, it was shown that a high surface recombination velocity was the most probable origin of the poor performance practically obtained for GaAs cells [21].…”

Among thin-film photovoltaic technology, cadmium telluride (CdTe) has achieved a truly impressive development that can commercially compete with silicon, which is still the king of the market. Solar cells made on a laboratory scale have reached efficiencies close to 22%, while modules made with fully automated in-line machines show efficiencies above 18%. This success represents the result of over 40 years of research, which led to effective and consolidated production processes. Based on a large literature survey on photovoltaics and on the results of research developed in our laboratories, we present the fabrication processes of both CdTe polycrystalline thin-film solar cells and photovoltaic modules. The most common substrates, the constituent layers, their interaction, the interfaces and the different “tricks” necessary to obtain highly efficient devices will be analyzed. A realistic industrial production process will be analytically described. Moreover, environmental aspects, end-of-life recycling and the life cycle assessment of CdTe-based modules will be deepened and discussed.

A calculated curve of the maximm efficiency that can be obtained as a function of the enersy gap of the semiconductor made into a p-n ~unction and illumimated with the solar spectrum outside the atmosphere, AMO (Loferski, 1963). N h represents the number of photons in AMl whose energies are greater than the bandgRp of silicon, E .…”
