PSCs possess qualities that find applications in civilian and military sectors.

This correspondence seeks to shed light on the current Department of Defense (DoD) efforts in PSCs, as well as demonstrate reduction in cost, environmental impact, and CO2 footprint. Successes in stabilization of the materials and challenges to be overcome for perovskites are discussed. This work shows the possibility of integrating perovskite materials with existing mature solar panel technologies for successful marketization of perovskites and diversification of applications. Furthermore, this work demonstrates the opportunities that are presented by perovskite materials to the DoD community and unique challenges that are overcome with the application of this technology.","PeriodicalId":145218,"journal":{"name":"Organic Photonics + Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129586440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Learning about how measurable signals can indicate the growth status of various plants will be beneficial for designing plant health monitoring systems (PHMSs) that can be used around the globe for the efficient growth of plants. In this work, we have designed and employed an array of gas sensors, acting as an electronic nose, to monitor the health status of lettuce being grown in a chamber by measuring the emission and consumption of various gases and volatile organic compounds (VOCs). While emission of ethylene is a strong indicator, we have found that accurate concentration measurements of CO2 and alcohols can also be used to assess the health status of the plant at its different stages of growth, particularly at the seedling and vegetative stages. ~20% change in the alcohol concentration and more than 2 folds increase in the equivalent CO2 level was observed when brown leaves started growing before the plant died. The results of the studies can help to design a simple PHMS that can help grow vegetables at a high yield with minimum supervision","PeriodicalId":145218,"journal":{"name":"Organic Photonics + Electronics","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128778573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here in this work we have synthesized and characterized a novel double perovskite material Cs2CuBiCl6 for the first time through an easy and commercial chemical route at ambient temperature. Further, we have investigated the morphological and optical behavior of synthesized double perovskite material. To check the crystallinity, phase formation, and purity of the DP, X-Ray diffraction (XRD) spectroscopy has been done at room temperature. A good crystalline and rhombohedral phase has been observed from the XRD plot, which is in good agreement with the reference data (ISCD#239874). Moreover, photoluminescence (PL) spectroscopy at room temperature (300K) of synthesized DP material has been done to observe its optical properties. A broad peak around 500 nm has been observed from the PL spectra corresponding to the energy of 2.5 eV, which further suggests the usefulness of the DP for visible range applications. The observed peak in the PL spectra is due to band-to-band transition and phonon-assisted carrier recombination of the excitons trapping. This novel study on the double perovskite material Cs2CuBiCl6 has opened a new path to develop optoelectronic devices based on non-toxic double perovskite material having better efficiency than the toxic counterpart.","PeriodicalId":145218,"journal":{"name":"Organic Photonics + Electronics","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123211831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colour conversion can be achieved by colour converting materials such as quantum dots (QDs) or light-emitting polymers. More efficiency and light intensity can be achieved using this colour conversion technique as compared to the mass transfer technique. The colour conversion technique works with a GaN-based blue colour chip and we don’t require the other two-colour diode chips which will ultimately save time and production cost by avoiding mass transfer for the fabrication of Micro-LED. In this experiment, we evaluated organic dye for red (DCJTB) and green (C545T) emitters in a water-resistant, strong binder like PVB as a host material under different solvents resulting in rare-earth element-free fluorescent films. These polymers generally contain polyols that have long chains of carbon and can be extended into the solvent easily and they act as an anchoring group. PVB being water repellent helps in moulding the film with higher efficiency (~ 90%) and enhanced stability under normal and humid conditions, resolving the issue of device degradation in the presence of water content in the case of OLED. The synthesis process is very simple, cost-effective, and non-toxic.","PeriodicalId":145218,"journal":{"name":"Organic Photonics + Electronics","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134181962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
