In today’s World the renewables are at the hub of almost all energy policy transitions to meet the increased needs of energy within the global developing economy and technology. Solar energy takes its part with largest growth rate of solar photovoltaic power plants. As the need for R/D on the subject is increasing and the steps are taken to improve the infrastructure, we organized the first of its series Photovoltaic Conference (PVCon) in July 2018 in Middle East Technical University Campus, Ankara, Turkey. The number of participants was 210, the proceedings are published in IEEE Xplore and the selected extended versions of articles are published in Renewable Energy Journal Special Issue. With the hope and willingness of the continuity of this conference we are pleased to announce second organization of the series: PVCon2020. The main aim is to present a well-established scientific and technical forum on solar photovoltaics (PV). We again plan to host international and national invited speakers, researchers, representatives of governmental bodies and private sector representatives. The participants will share the recent researches and developments of the science and technology about solar energy and solar PV, contributing to the development of the related R/D and infrastructure, and in the meantime establishing a fruitful platform of national and international collaborations.
