Although inorganic solar cells presently provide higher efficiencies, the high cost and energy-consuming production process limit their wide application. Therefore, extensive studies have investigated new inexpensive organic photovoltaic systems. Recently, polymers have been studied widely in this promising area owing to their versatile and adjustable physical and chemical properties, among which organic solar cells (OSCs) and perovskite solar cells (PSCs) have attracted considerable attention due to their advantages of low cost, lightweight, and flexibility. Especially in the photocatalysis area, polymers can be used to modify photo-corrosive semiconductors to improve the efficiency and stability of solar hydrogen production. Therefore, based on the important roles that polymers play in high-efficiency solar cells and solar hydrogen generation, we herein provide a mini review on the major applications of polymers in energy conversion and storage fields.","PeriodicalId":175500,"journal":{"name":"Annals of Chemical Science Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130831025","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}

Secondary batteries are superior to other energy storage technologies due to their high energy density and conversion efficiencies (Figure 1). In recent years, secondary lithium-ion batteries become an integrated part of our life due to its widespread use in consumer electronics, medical devices and electric vehicles [1]. However, implementation of current generation lithium-ion batteries (LIBs) in commercial electric vehicles are limited by their low energy density (100-250Wh kg-1) and power density (250-400W kg-1) [2]. Pack level energy density exceeding 350Wh kg-1 is necessary for electric vehicles with a driving range of 500km [3]. In this regard, many approaches are being pursued to improve the electrochemical performance of Li-ion battery electrochemistry with the use of high-performance nanostructured electrode materials.","PeriodicalId":175500,"journal":{"name":"Annals of Chemical Science Research","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114584166","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}

Uses of polymer in perovskite material lead to crystallization processes and work as an additive to adjust the nucleation. These polymers are generally used as an electron transfer material, hole transfer material or interface layer and work like to reduce the recombination rate and improves the separation efficiency of the charge carriers [1]. Polymers are often used as buffer layers or donor layers in inorganic solar cells. Some polymer nanostructured are used to enhance device performance [2,3]. Some low bandgap polymer materials are used as a hole transporting material in perovskite solar cells (PSC) to optimize efficiency as well as prevent cell degradation. Researchers are using a polymer-perovskite composite material to fabricate hybrid structures that are widely used in perovskite-based light-emitting diode (LED). Polymers encapsulated perovskite solar cell has a comparative longer lifetime and less degradation of materials than without encapsulation [4]. The light absorption of Perovskite layer is less impacted by the polymer coating. Though polymers have a lot of advantages for uses in perovskite solar cell some issues like thermal stability in high temperature, water permeability through polymer layer and adhesive property of thin layer is challenging and lot of research work is going on to address the challenges [5]. Recent trends of polymers application in perovskite-based solar cells and its achievements are reviewed and discussed in this article. Moreover, the practical challenges of polymer layered perovskite solar cell and implementation techniques are addressed.","PeriodicalId":175500,"journal":{"name":"Annals of Chemical Science Research","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124408900","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}

It is a hybrid of quantum mechanics and molecular mechanics. It utilizes quantum mechanics to describe regions of high priorities in a system. This method is usually very accurate when the right parameters are used. Additionally, DFT uses molecular mechanics force fields to describe the remaining atoms in the system [2]. This method does not need to be as accurate since it is not used on the region of focus. The improvements made to DFT during the late twentieth century have expanded its application across the disciplines of chemistry and physics. Most recently, these calculations have been used to describe biological molecules. However, even the simplest biological molecules tend to be large compared to those studied in physical science. Therefore, the computational cost would be exuberant if other Ab inito methods were used. DFT can be applied to these large systems because it offers a good balance between accuracy and computational cost.","PeriodicalId":175500,"journal":{"name":"Annals of Chemical Science Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131355512","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}
