Proceedings of 9-th European conference on renewable energy systems (ECRES 2021), 21-23 April 2021, Istanbul , Turkey
The event has been organized in Istanbul/Turkey on 21-23 April 2021 by the local organizers ECERG – Electrical and Computer Engineering Research Group at Gazi University and PROJENIA in the virtual format. Besides, many institutions world-widely took a part as the cooperating institutions including many international refeered academic journals.
Historically, the first, second, third, fourth, fifth, sixth, seventh and eighth conferences were completed very successfully in Alanya/Antalya (2012), Antalya (2013), Kemer/Antalya (2015), Istanbul (2016), Sarajevo / Bosnia and Herzegovina (2017), Istanbul (2018), Madrid (2019), Istanbul-remote (2020), respectively.
Many of the extended forms of selected papers were puublished in SCI, E-SCI and SCOPUS indexed reputable journals following the previous events. This year, 225 papers have been received world-widely. Among them, 146 papers from 40 countries have been accepted by the scientific committee. Following the virtual presentation of the authors, these papers are put into the proceedings. We gratitute all authors, keynote speakers, special session organizers, reviewers, session chairmen and scientific board for their precisious contribution aand hope to extend these cooperation for the next events, too.
The purpose of the ECRES is to bring together researchers, engineers and natural scientists from all over the world, interested in the advances of all branches of renewable energy systems such as wind, solar, hydrogen, hydro-, geothermal, solar concentrating, fuel-cell. It aims to present and disseminate the cutting-edge results to the international community of energy in the form of research, development, applications, design and technology. It is thereby expected that it can assist researchers, scientists, manufacturers, companies, communities, agencies, associations and societies to keep abreast of new developments in their specialist fields and to find innovative solutions in their problems.
For effective design of betavoltaic structures with trenches the original TCAD-model was designed and verified. The standard TCAD optical generation model “optical beam” was adopted for simulation of electron-hole generation for beta particles irradiation in element structure with 5-um width vertical micro trenches.
