The production of high power modules in limited area requires high efficiency solar cells. Shingled photovoltaic modules can be made by divided solar cells, which can be produced by the laser scribing process. After dividing the 21% PERC cell using laser scribing, the efficiency decreased by approximately 0.35%. However, there was no change in the efficiency of the solar cell having relatively lower efficiency, because the laser scribing process induce higher heat damages in solar cells with high efficiency. To prove this phenomena, the J0 (leakage current density) of each cell was analyzed. It was found that the J0 of 21% PERC increased about 17 times between full and divided solar cell. However, the J0 of 20.2% PERC increased only about 2.5 times between full and divided solar cell.","PeriodicalId":17325,"journal":{"name":"Journal of The Korean Institute of Electrical and Electronic Material Engineers","volume":"15 1","pages":"291-296"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78852410","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}

CNT fuses were fabricated in the form of universal modular fuse (UMF) with different diameter of CNT fibers defined by multiplying the CNT threads. Electrical properties of the CNT fuses were measured such as resistance, rated current, and operation time with current. Resistance of the CNT fuse decreased and rated current increased with the diameter of the CNT fuses, respectively. Consequently, the operation time with current increased with the diameter of the CNT fuses. The CNT fuses fabricated in this work had broad range of low rated current from 0.05 to 1.25 A by multiplying the CNT threads. Operation time was measured about 3.6ms which was applicable to the UMF.","PeriodicalId":17325,"journal":{"name":"Journal of The Korean Institute of Electrical and Electronic Material Engineers","volume":"19 1","pages":"45-49"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83354872","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}

The crystal structure of the polymer material is advantageous for mechanical properties and heat-resistance. However, the polymer acts as an inhibitor to the dispersibility of carbon black. The purpose of this study is to develop a TPE semiconductive compound technology. The high heat resistance and ultra-smoothness characteristics which are required for high voltage and ultra-high voltage cables should be satisfied by designing and optimizing the structure of a non-crosslinking-type eco-friendly TPE semiconductive compound. The application of excess TPE resin was found to not only inhibit the processability in the compounding process, but also reduced the dispersion properties of carbon black due to higher crystallinity. After the crystallinity of the compound was identified through DSC analysis, it was compared with the related dispersion characteristics. Through this analysis and comparison, we designed the optimal structure of the eco-friendly TPE semiconductive compound.","PeriodicalId":17325,"journal":{"name":"Journal of The Korean Institute of Electrical and Electronic Material Engineers","volume":"8 1","pages":"400-404"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79427125","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}
