In 2025, the UK generated over 14 billion kilowatt-hours of solar electricity, enough to power more than 5 million homes. With solar technology evolving faster than ever, could the next leap in solar power come from labs pushing the boundaries of energy science?

Host - Prof. Christos Markides - Clean energy technologies in the department of Chemical Engineering at Imperial

Guest  - Dr Flurin Eisner - Lecturer and researcher in Green Energy and Sustainable Engineering at Queen Mary University

Topics Discussed 

• Technology improvements in solar cells
• Generation capacity for manufacturing solar technologies
• Growth rate of PV industry
• Technical dive into converting solar power to energy
• Solar heat converted to cooling technologies
• UK’s Solar PV generation vs that of Europe.
