INTERNATIONAL ENERGY AGENCY IEA PVPS The International Energy Agency (IEA), founded in November 1974, is anautonomousbody within the framework of the Organisation forEconomic Cooperation and Development(OECD), which carries out acomprehensive programme of energy cooperation among its member The IEA Photovoltaic Power Systems Programme (PVPS) is one of theTechnology Collaboration Programmes (TCP) established within theIEA, and since its establishment in 1993, the PVPS participants have Theoverall programme is headed by an Executive Committeecomposed of representatives from each participating country and The IEA RD&D activities are headed by the Committee on Research andTechnology(CERT),supported by the IEA secretariat staff,withheadquarters in Paris. In addition,fiveWorking Parties onIndustrialDecarbonization,Building and Transport,FossilEnergy and CarbonManagement, Renewable Energy Technologies and Fusion Power, are By the beginning of 2026, twenty Tasks were established within the PVPSprogramme, of which nine are currently operational. The thirty-onePVPS membersinclude twenty-eight countries: Australia, Austria,Belgium, Canada, China, Denmark, Finland, France, Germany, India,Israel,Italy,Japan,Korea,Lithuania,Malaysia,Morocco,the The Renewable EnergyTechnologiesWorking Party (REWP) overseesthe work oftwelverenewable energy agreements and is supported by CURRENT TERM 2023-2028 MISSION AND OBJECT IVES In its 7th term from 2023 to 2028 IEA PVPS continues its commitment toadvancinginternational cooperation in the field of photovoltaictechnology. With 31 member countries contributing to its success overthe past33 years, PVPS outlines a strategic orientation aimed atsupporting the overarching goals of IEA in terms of energy security, The mission of the IEA PVPS programme is: Enhance the international collaborative efforts which facilitate The IEA PVPS programme aims to realise its mission through thefollowing objectives related to reliable PV power system applications,contributing to sustainability in the energy system and a growing The significance of photovoltaic technology has been steadily rising,withits emergence as one of the most cost-effective means ofelectricity production. Its attributes,including rapid deployability, easeof installation, and minimal maintenance costs,have positioned it as a •PV technology development •Competitive PV markets •An environmentally and economically sustainable PV industry •Policy recommendations and strategies IEAPVPSparticipantsareundertaking collaborative effortsencompassing research, development, demonstration, analysis, andinformationexchange related to photovoltaic power systems.Emphasizing both technical and non-technical aspects, the aim is to •Impartial and reliable information. Lookingbeyond 2030,the strategic plan anticipates addressingforthcoming challenges such as physical, technical, and economicintegration,alongside policy,regulatory,and social acceptanceconsiderations. Collaboration with stakeholders from diverse energy RESEARCH HIGHLIGHTS 2025 In 2025 there were over 350 Experts from 29 countries participating inthe global collaborative research activities of IEA PVPS. In total, theypublished 30 reports and 7 Fact Sheets during
