“…In [34], they propose a complete method for studying long-term light entrapment, the use of quantum efficiency data, and expressions of the calculation of Z0 and RBACK (reflectivity of the rear reflector defined in [10] for any solar cell), where Z0 is the optical path of short band length factor Z0 of Rand and Basore [35], and it is a multiple of the thickness of the cell necessary to generate equal to that found in the device. Although there are not very relevant nodes as compared to the others, it should be noted that the publications of the most cited nodes in Scopus for this scientific community in order of size are:…”

This paper describes the characteristics of contributions that were made by researchers worldwide in the field of Solar Coating in the period 1957–2019. Scopus is used as a database and the results are processed while using bibliometric and analytical techniques. All of the documents registered in Scopus, a total of 6440 documents, have been analyzed and distributed according to thematic subcategories. Publications are analyzed from the type of publication, field of use, language, subcategory, type of newspaper, and the frequency of the keyword perspectives. English (96.8%) is the language that is most used for publications, followed by Chinese (2.6%), and the rest of the languages have a less than < 1% representation. Publications are studied by authors, affiliations, countries of origin of the authors, and H-index, which it stands out that the authors of China contribute with 3345 researchers, closely followed by the United States with 2634 and Germany with 1156. The Asian continent contributes the most, with 65% of the top 20 affiliations, and Taiwan having the most authors publishing in this subject, closely followed by Switzerland. It can be stated that research in this area is still evolving with a great international scientific contribution in improving the efficiency of solar cells.

“…Initial theoretical analysis based on thermodynamic considerations (Brendel 2003) suggested that rough surfaces and an asymmetric cell structure would effectively enhance optical absorption in the cell. Surface texturing, which was initially introduced to reduce surface reflectance for broadband illumination, also resulted in an increase in the optical path of light transmitted into a Si wafer (Yablonovitch 1986;Sopori 1988;Barnett et al 1991;Abenante 2006;Mutitu et al 2008). Following the initial success, texture etching became a standard process step for fabricating Si solar cells, both in the laboratory and commercially.…”

“…This implies that the wafer thickness for sufficient absorption of the solar spectrum is >700 μm. This is quite a large thickness for a Si wafer and is not desirable for commercial production of solar cells for two reasons: the wafer cost can be very high and its effectiveness for collection of photogenerated carriers will be small because it is difficult to have a minority-carrier diffusion length comparable to such a large wafer thickness (Yablonovitch 1986;Sopori 1988;Barnett et al 1991;Abenante 2006;Mutitu et al 2008). Thus, for practical reasons, wafer thickness must be less than this value.…”

In this work, the construction of an (Al + Ag)/n + -Si/p-Si/Al thin-film silicon (TF-Si) solar cell is presented. The maximum achievable current density generated by a planar solar cell, with an optimum antireflection coating, for different values of the cell thickness are analysed. Both electrical and optical properties of (Al + Ag)/n + -Si/p-Si/Al TF-Si solar cell have been studied, which assumes the generation of one electron-hole pair per photon and a collection efficiency of unity. A reduction in thickness can lead to an increase in V OC , it can have the opposite effect if surface recombination is not reduced simultaneously. Thin-film solar cell has an absorbed photon flux density about three times higher at each interface, implying that carrier generation at the interfaces of the thinner cell is about three times higher. Finally, for larger grain size, the recombination at the grain boundaries (GBs) of Si will mainly degrade V OC , and not J SC . From the obtained results, it is evident that the larger the grain size, the better the performance of the device. However, the interface recombination has a strong influence on each parameter.
