Today, the need for primary and secondary energies is always increasing to meet the energy needs of mankind. In recent years, solar cells have been used as an alternative to produce renewable, sustainable, and pollution-free energy. Various materials have been used as the transfer layer in cells. TIO2 is one of these materials that has been widely used as the electron transfer layer, but currently, ZnO is another significant material. is more recently used than TIO2. Also, perovskite solar cells are (...) the new generation of solar cells that belong to the nano family. Currently, perovskite solar cells (PSC) as a promising cell in the electronics industry, due to the high-power conversion efficiency, as well as the relatively lower cost of manufacturing a silicon solar cell, and such high flexibility that leads to the use of Perovskite is on different types of substrates. Also, the use of graphene as the most important fundamental photovoltaic material for photovoltaic energy conversion has emerged and been used. Graphene is used as a transparent electrode, as an active layer between layers, as an electron and hole transfer layer, or as an electron and hole separator layer in the construction of solar cells. In this article, the goal is to find the best structure with the highest power conversion efficiency in solar cells, and we will see further that by using perovskite, ZnO, and graphene, we will achieve a power conversion efficiency of 16% with a low manufacturing cost.

BackgroundMedical education is currently more considerate about the human dimension. The present qualitative study aimed to explain the experiences of clinical professors with regard to humanism in clinical education in Iran.MethodsThis mixed methods study had two phases, a quanitative phase of scientometrics and a qualitative phase of a content analysis. In the scientometrics phase, Ravar PreMap and VOSviewer software programs were utilized for plotting the conceptual networks. The networks were analyzed at the micro-level based on centrality indices. The conceptual network (...) was plotted and the prominent topics in clinical education were identified using co-word analysis. In the second qualitative phase on the topic, based on the scientometrics phase, semi-structured interviews were conducted with clinical professors. The interviews were transcribed verbatim and analyzed.ResultsOn the basis of the analysis of titles, abstracts, and keywords of the retrieved articles on clinical education from ISI Web of Science, Scopus, and PubMed, 1412 keywords were extracted. After the refining process, 356 keywords with 6741 relations remained. Upon plotting the conceptual network, 19 conceptual clusters related to clinical education were obtained. Then, micro-level network analysis indicated that the keyword humanism with the frequency of 137 had the highest rate, closeness, and betweenness. Moreover, from the interview data analysis, two themes of “intertwined nature of the human spirit in clinical education” and “humanistic behavior of professors in clinical education” were extracted.ConclusionAs a part of the educational culture, humanistic values must be intertwined with the medical education curriculum. In this regard, humanism and clinical reasoning are the two major clusters of clinical teaching; moreover, altruism and adherence to humanistic values, and scientific qualification are other main pillars that should be considered as the criteria for the selection of clinical professors and medical students.
