“…According to [20], when a CdTe surface is etched in a solution of bromine in methanol and diffused into the base layer of copper near the surface, an interlayer of p+ type of electrical conductivity is formed, which provides a low contact resistance. It was shown in [21] that the copper diffusion at a copper layer thickness of 10 nm leads to the degradation of the output characteristics of the solar cell. On the other hand, in the development of bifacial sensitive solar cells on a glass substrate [22], it was shown that without the use of copper these solar cells have a low efficiency.…”

By the method of nonreactive high-frequency magnetron sputtering on Upilex polyimide films, transparent and conductive layers of ITO were obtained. These layers, after high-temperature annealing, at temperatures typical for the solar cell formation, had a resistance of 11 ohm/□ and a transmittance of up to 72%. The use of such an ITO layer with the addition of a 100 nm thick layer of undoped zinc oxide, as the front contact, and Cu/ITO composition, as the back contact, made it possible to obtain a flexible solar cell polyimide/ITO/CdS/CdTe/Cu/ITO with an efficiency of 10.4%. With a thickness of the base layer of cadmium telluride 2.5 μm, the average transmittance of the SC in the 850-1100 nm wavelength range is 46.8%. The developed design of a flexible solar cell based on cadmium telluride due to the use of a transparent back contact with a comb metal electrode is easily interfaced with existing designs of flexible solar cells based on copper and indium diselenide, which allow the formation of flexible tandem photoelectric converters CdTe/CuInSe2.

“…Single crystals and films of A 2 B 6 semiconductor compounds, in particular CdS, and related multilayer heterostructures are widely used for the creation of various micro-, nano-, and optoelectronic devices, including those for solar power engineering [1][2][3][4]. At present, the influence of heat treatments, laser annealing, microwave processing, and the ion and electron bombardment on the structure, composition, and optical properties of A 2 B 6 compounds and the process of atomic interdiffusion at the interfaces of multilayer systems based on these semiconductors have been thoroughly studied [5][6][7][8][9][10][11][12][13].…”

Adsorption of Ba Atoms Influences the Composition, Emission, and Optical Properties of CdS Single Crystals

We have studied the composition, electron emission, and optical properties of CdS single crystals covered by a surface film of adsorbed Ba atoms with thickness Θ from 0.5 to 5 monolayers (ML). It is established that, as Θ increases up to 1 ML, yield depth λ of true secondary electrons (and photoelectrons) in the emission zone exhibits significant growth, which is explained by decreasing work function of the material surface. The further increase in Θ is accompanied by a decrease in both λ and photocurrent intensity values. It is found that no significant mutual diffusion of atoms at the Ba-CdS interface takes place at room temperature. Upon heating to T = 700 K, sulfur atoms exhibit intense diffusion into the Ba film and form a surface compound of the Ba 2 S type.

“…This is initially coated with an n-type cadmium sulphide (CdS) window layer and secondary with the ptype CdTe absorber layer. CdTe technology has the lowest production costs among the current thinfilm modules, and is some of the most promising for wide scale application (Khrypunov et al 2011). The colour is reflective dark green to black and typical cell efficiencies are 9.4-13.8% (Buecheler et al 2011, Khrypunov et al 2011, The German Energy Society (DGS) 2008.…”

Building integrated photovoltaics (BIPVs) are photovoltaic (PV) modules integrated into the building envelope and hence also replacing traditional parts of the building envelope, e.g. the roofing. In this context, the BIPVs integration with the building envelope limits the costs by serving dual purposes. BIPVs have a great advantage compared to non-integrated systems because there is neither need for allocation of land nor stand-alone PV systems. This study seeks to outline various commercially available approaches to BIPVs and thus provides a state-of-the-art review. In addition, possible future research opportunities are explored.The various categories of BIPVs may be divided into photovoltaic foils, photovoltaic tiles, photovoltaic modules and solar cell glazings. Silicon materials are the most commonly used, and a distinction is made between wafer-based technologies and thin-film technologies. In addition, various non-silicon materials are available. The main options for building integration of PV cells are on sloped roofs, flat roofs and facades. The evaluation of the different BIPV products involves, among others, properties such as solar cell efficiency, open circuit voltage, short circuit current, maximum effect and fill factor.It is expected that the BIPV systems will improve in the years to come, regarding both device and manufacturing efficiency. The future seems very promising in the BIPV industry, both concerning new technologies, different solutions and the variety of BIPV options.
