Preface

Abstract

This Proceedings contains the selected papers of the 2023 3rd International Conference on Energy Engineering, New Energy Materials and Devices (NEMD 2023), which was held via virtual form in Guangzhou, China from March 24th to 26th, 2023.NEMD 2023 is aimed at the academic and scientific community and the productive sectors of the region, with the aim of disseminating academic and research work; moreover, promotes the exchange of experiences between researchers as well as the participation of the productive sectors in research, extension, technological development, and innovation activities, contributing to the strengthening the relationship between universities, enterprises and institutions.This Conference was articulated with different topics around the themes of Energy Engineering, New Energy Materials and Devices to discuss on the research findings, their possibilities and challenges. The relevance of the NEMD 2023 conference theme to a wide range of disciplines is reflected in the papers that have been submitted for publication. The topics covered in the Proceedings includes: Solar Photovoltaic Power Generation System, Principle and Technology of Solar Cell, Distributed Energy System Technology, Energy Conversion and Application, Green Energy Materials, etc.. All the papers, being reviewed through a double-blind review process, are original contributions to the topics and shown the research works that are doing in the field of the described theme.We had about 60 participants all around the world. The scientific program of the Conference was composed of keynote speech, oral presentation, and academic investigation. Assoc. Prof. Jing Guo from Xi’an Jiaotong University, China, who has published more than 80 academic publications, over 4600 SCI citations, with an H-factor of 40 (Google Academic), made a keynote speech on Ceramic-Polymer Composites Prepared via Cold Sintering Process. Ceramicpolymer composites have attracted much attention due to the excellent combined physical and chemical properties. However, most of the ceramics are sintered at high temperatures, typically higher than 1000 °C, which are not compatible with the processing temperatures of polymers. Thus, it is challenging to integrate ceramics with polymers in a onestep sintering process. Cold sintering process proposed in 2016 provides a route for the densification of ceramics at temperatures lower than 350 °C. He discussed the recent development of cold sintered electronic materials based on ceramic-polymer composites. The brilliant speeches of each speaker provided a feast of knowledge for all the participants, allowing them to communicate with each other and get some academic advice or suggestion.Our sincere thanks and gratitude to all the participants for making such a comprehensive NEMD Conference and Proceedings, which contribute to the enhancement and development in related fields. We are grateful to the Technical Program Committee for their valuable time and advice. Special thanks to the members of the Journal of Physics: Conference Series for making this Proceedings published. We appreciate the effort from those involved and look forward to a more successful conference next year.The Committee of NEMD 2023Committee Member are available in the pdf
