Photovoltaics today in Daejeon: WCPEC-9 2026

A global photovoltaic gathering held every four years

In its 18 August press release, Daejeon Metropolitan City described the event as an international gathering held every four years that brings together major photovoltaic conferences from the United States, Europe and Asia. The official website lists the Ministry of Climate, Energy and Environment, Daejeon Metropolitan City and the Korea Photovoltaic Society as hosts. The academic conference runs for six days, while the exhibition is open only from 16 to 19 November, so plan the two parts of your visit around the dates that interest you.

Solar & Green-Energy Show: 16–19 November at DCC2

The exhibition runs daily from 10:00 to 18:00 in Halls 1–4 of DCC Exhibition Center 2. Its main fields include solar cells and modules, materials, power conversion systems, photovoltaic mounting structures and installation, and energy storage systems. Hydrogen fuel cells, wind power, smart grids and environmentally friendly mobility will also be introduced.

Advance exhibition registration has closed, so exhibition visitors must now register on site. Exhibition registration does not provide admission to the academic conference in DCC1. Participants who have completed paid conference registration can visit the exhibition without registering for it separately.

Register for the academic conference on site and check the conditions first

Online academic registration closed on 30 October; registration after that date is available only on site. According to the attachment to the 29 October notice, on-site registration costs KRW 900,000 for regular participants and KRW 300,000 for students. On-site payment is by credit card in Korean won only. Students must bring a student ID or proof of enrolment. Some programmes, such as tutorials, the welcome reception and the banquet, may be unavailable once they reach capacity, so check the programmes that interest you first.

If you have already registered, check the cancellation deadline too. Cancellations made by 4 November receive a full refund of the registration fee; no refunds are available from 5 November. Exceptions apply to cancellations caused by infectious disease or visa issuance problems. A cancellation is confirmed only after you submit the cancellation form by email and receive a confirmation reply from the secretariat. Registration cannot be transferred to another participant.

Visit IEA PVPS and the industry forum together

The International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS) will introduce international collaborative research, its latest publications and ongoing research at Booth W-30 from 16 to 19 November. At 14:50 on 18 November, Executive Secretary Emily Mitchell will introduce the programme and its international cooperation at the exhibition’s industry forum. If you are interested in research collaboration, you can plan to attend the presentation and visit the booth together. If products or installation are your focus, choose relevant companies from the official exhibitor list.

Check these details before your visit

If you are visiting only the exhibition, you can register on site in the first-floor lobby of DCC2. Exhibition visitor registration runs from 09:00 to 17:00, which differs from the exhibition’s opening hours. If you registered in advance, bring the Smart Pass QR code received by email or text message and collect your wristband at the registration desk.

For enquiries, email registration@wcpec-9.com for registration or exhibition@wcpec-9.com for the exhibition, or call the secretariat on 02-6918-2554.
