Vacuum vapor deposition protocols were less studied, but have nevertheless received increasing attention from industry and academia due to the great potential for large-area module fabrication, facile integration with tandem solar cell architectures, and compatibility with industrial manufacturing approaches.

Predicting the relative permittivity of particle/polymer nanocomposites from the microstructure is of great significance. However, the classical effective medium theory and physics-based numerical calculation represented by finite element method are time-consuming and cumbersome for complex structures and nonlinear problem. The work explores a novel architecture combining the convolutional neural network (ConvNet) and finite element method (FEM) to predict the relative permittivity of nanocomposite dielectrics with incorporated barium titanite (BT) particles in polyvinylidene fluoride (PVDF) matrix. The ConvNet was trained and evaluated on big datasets with 14266 training data and 3514 testing data generated form a programmatic algorithm. Through numerical experiments, we demonstrate that the trained network can efficiently provide an accurate agreement between the ConvNet model and FEM by virtue of the significant evaluation metrics \u0000<tex>$R^{2}$</tex>\u0000, which reaches as high as 0.9783 and 0.9375 on training and testing data, respectively.

In particular, there has been a major focus placed on the carbon produced through electricity generation, as it is responsible for roughly 30% of emissions globally, per the United States Environmental Protection Agency (EPA). When renewable energy solutions are advanced very heavily, that raises the level of tension among competing interests. This needs to be navigated very carefully if we are to meet carbon reduction targets, which in turn need to be shared based on historical contributions and current emission levels. A nuanced approach to navigating this tension will see industrialized nation states collaborating with emerging economies to deploy a portfolio of solutions with low-carbon generation, storage and demand side management with advanced technology focusing on energy efficiency. To more efficiently facilitate the global shift towards renewable energy adoption, the below six areas should be our priority.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"1 3","pages":"269-269"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9732629/9954281/09954353.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50209232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
