Funds projects advancing scalable, innovative tandem PV technologies to strengthen EU solar manufacturing and support the solar energy innovation agenda.

--- ## Description This European Commission call supports research and innovation actions aimed at advancing industrial processes and equipment for innovative, reliable, and scalable tandem photovoltaic (PV) technologies. The goal is to accelerate the commercialisation of competitive tandem PV technologies, contributing to the EU’s solar deployment and manufacturing targets, supporting the EU Solar PV Industry Alliance, and aiding the joint solar energy research and innovation agenda. Projects should demonstrate technologies with lifetimes comparable to silicon, higher efficiencies, large-scale engineering, and readiness for industrial deployment. A strong business case and exploitation strategy are required, including plans for scalability and commercialisation. Projects must report on key performance indicators to the European Partnership for Innovation in Photovoltaics (EUPI-PV). --- ## Due Dates - December 1, 2027: Full application submission deadline (single-stage) --- ## Funding Amount - Total available: €28,500,000 (2027 call) - Typical project grant: ~€9,500,000 - Expected number of grants: 3 --- ## Eligibility - Open to legal entities from EU Member States and countries associated with Horizon Europe (see [Annex B](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/wp-call/2026-2027/wp-15-general-annexes_horizon-2026-2027_en.pdf)) - Additional eligibility and admissibility conditions apply as per the [Horizon Europe General Annexes](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/wp-call/2026-2027/wp-15-general-annexes_horizon-2026-2027_en.pdf) - Proposals must address the demonstration of tandem PV technologies at scale, with clear plans for exploitation and commercialisation --- ## Application Process - Single-stage submission via the [EU Funding & Tenders Portal](https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-details/HORIZON-CL5-2027-07-D3-16?isExactMatch=true&status=31094501,31094502&order=DESC&pageNumber=1&pageSize=50&sortBy=startDate) - Application form and templates are available in the portal's Submission System ([Standard application form](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/temp-form/af/af_he-ria-ia_en.pdf)) - Proposals must include a detailed exploitation and dissemination plan, business case, and preliminary plans for scalability and commercialisation - Evaluation criteria and scoring as per [Annex D](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/wp-call/2026-2027/wp-15-general-annexes_horizon-2026-2027_en.pdf) - Consult the [Online Manual](https://webgate.ec.europa.eu/funding-tenders-opportunities/display/OM/Online+Manual) for step-by-step guidance --- ## Additional Information - Projects are expected to support EU solar manufacturing goals and contribute to the resilience and competitiveness of the European PV value chain - Reporting to the EUPI-PV partnership is required for monitoring progress and KPIs - For further guidance, see the [Horizon Europe Programme Guide](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/guidance/programme-guide_horizon_en.pdf) --- ## External Links - [Call Details & Application Portal](https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-details/HORIZON-CL5-2027-07-D3-16?isExactMatch=true&status=31094501,31094502&order=DESC&pageNumber=1&pageSize=50&sortBy=startDate) - [Horizon Europe General Annexes](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/wp-call/2026-2027/wp-15-general-annexes_horizon-2026-2027_en.pdf) - [Horizon Europe Programme Guide](https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/horizon/guidance/programme-guide_horizon_en.pdf) - [Online Manual](https://webgate.ec.europa.eu/funding-tenders-opportunities/display/OM/Online+Manual) --- ## Contact Information | Type | Details | |-------------------------|------------------------------------------------------------------------------------------------------------| | Funder | [European Commission](https://commission.europa.eu/index_en) | | General Enquiries | [Contact the European Commission](https://commission.europa.eu/about-european-commission/contact_en) | | Phone | +32 2 299 11 11 | | Research Enquiry Service| [Research Enquiry Service](https://research-and-innovation.ec.europa.eu/contact-us/research-enquiry-service_en) | | National Contact Points | [Find your NCP](https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/support/ncp) |
