To date, many methods have been suggested to improve the performance of materials in various applications by applying new physical and chemical properties at the nanometer scale in the form of nanodots, nanowires, and nanofi lms. However, most of the proposed methods are diffi ...
All-perovskite tandem solar cells (TSCs) show great potential for achieving effi ciencies beyond the Shockley–Queisser limit owing to their excellent photovoltaic properties and cost eff ectiveness. In this review, the current status of all-perovskite TSCs as well as recent re...
In this study, carbon black was used to manufacture electrical conductive mortar, and the carbon black and mixing water were controlled. In carbon black, secondary particles were formed with primary particles sized 100 ~ 300 nm and the electrical conductivity was measured at 19...
