The present scientometric study assesses the publication output of the scientists of Indian Association for the Cultivation of Science (IACS) during 2008 to 2017 as reflected in the Web of Science database to figure out the research performance, scholarly communication behaviour and its citation impact. The scientists of IACS contribute total 4,304 research articles including 22.58 percent international collaborated articles. Further, the publications have been evaluated in terms of year, types of collaboration, authorship pattern, source journals, impact factor, collaborating institutions, collaborating countries and citations. It is found that majority of the published articles are produced by three authored and the international collaborated articles which receive wider citation impact. The developed countries like USA, Japan, Germany and England are found as the most favoured countries by the scientists of IACS for research collaboration and the Journal of Physical Chemistry C shares maximum research articles. Further, Pareto’s 80/20 principle has also been applied to examine the scattering of journals as well as articles and the VOS viewer software has been used for mapping the network of collaborating countries.

Web of Science (WoS) is covering Biointerface Research in Applied Chemistry (BRIAC) from 2015 onwards. However, we performed its 1st bibliometric analysis of the last five years (from 2016 to 2020). The data from WoS was retrieved on 8th February 2021. In this period, BRIAC has published seven hundred and fifty-seven documents (n=757), majorly comprising research articles (n=665), reviews (n=86), and editorials (n=6). In all publications, exactly 2519 authors, 838 institutes or departments, and 77 countries have contributed. For numerical representations, we designed the publication and citation clubs. One thousand four hundred and thirty-four (n=1434) citations were noted. The total h-index was found to be 11, while the citation per item was recorded to be 1.89. The unofficial impact factor is 1.93. The calculation is based on citations in 2020 (498), divided by papers published in 2018-2019 (258). By VOSviewer analysis, we also represented the co-authorship network for authors, institutes, and countries. Four thousand nine hundred and thirty-eight (n=4938) keywords were noted in all publications. By co-words analysis, we represented the trends in publications. From WoS, we retrieved the per year h-index, citation per item, and total citations of BRIAC. It is worthy to note that BRIAC has accepted 600 research articles for the year 2021. All issues in 2021 are already published in advance. The present research article (bibliometric report) is paper number 600th, and it is closing the year. Based on the data, it can be concluded that in a short span of the last five years, BRIAC showed positive growth.

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]fluorene which can be synthesized via mildly air-sensitive techniques and the end products handled readily under atmosphereic conditions. Through transmetallation via diarylzinc reagents a series of derivatives were sythesized which show broad absorption profiles that highlight the versatility of this backbone to be used in organic solar cell devices. These compounds can be synthesized in large yields, in alow number of steps and functionalized at many stages along the way providing a large depth of possibilities. Exploratory device paramaters were studied and show PCE of 2%.

Abstract Conventional series resistance imaging methods require electrical contacts for current injection or extraction in order to generate lateral current flow in the solar cell. This paper presents a new method to generate lateral current flow in the solar cell without any electrical contacts. This reduces the sample handling complexity for inline application and allows for measurements on unfinished solar cell precursors.

This paper numerically explores the possibility of ultrathin layering and high efficiency of graphene as a back surface field (BSF) based on a CdTe solar cell by Personal computer one-dimensional (PC1D) simulation. CdTe solar cells have been characterized and studied by varying the carrier lifetime, doping concentration, thickness, and bandgap of the graphene layer. With simulation results, the highest short-circuit current (Isc = 2.09 A), power conversion efficiency (h = 15%), and quantum efficiency (QE ~ 85%) were achieved at a carrier lifetime of 1 × 103 ms and a doping concentration of 1 × 1017 cm−3 of graphene as a BSF layer-based CdTe solar cell. The thickness of the graphene BSF layer (1 mm) was proven the ultrathin, optimal, and obtainable for the fabrication of high-performance CdTe solar cells, confirming the suitability of graphene material as a BSF. This simulation confirmed that a CdTe solar cell with the proposed graphene as the BSF layer might be highly efficient with optimized parameters for fabrication.

Crucial Parameter

In this paper, a randomly distributed plasmonic aluminum nanoparticle array is introduced on the top surface of conventional GaAs thin-film solar cells to improve sunlight harvesting. The performance of such photovoltaic structures is determined through monitoring the modification of its absorbance due to changing its structural parameters. A single Al nanoparticle array is integrated over the antireflective layer to boost the absorption spectra in both visible and near-infra-red regimes. Furthermore, the planar density of the plasmonic layer is presented as a crucial parameter in studying and investigating the performance of the solar cells. Then, we have introduced a double Al nanoparticle array as an imperfection from the regular uniform single array as it has different size particles and various spatial distributions. The comparison of performances was established using the enhancement percentage in the absorption. The findings illustrate that the structural parameters of the reported solar cell, especially the planar density of the plasmonic layer, have significant impacts on tuning solar energy harvesting. Additionally, increasing the plasmonic planar density enhances the absorption in the visible region. On the other hand, the absorption in the near-infrared regime becomes worse, and vice versa.
