• Biological approaches to artificial photosynthesis, fundamental processes and theoretical approaches

Key points for discussion will include learning, understanding, and modifying nature to approach artificial photosynthesis:
How does nature exert efficient water oxidation?
What is the structure of the reaction centre? 
How does nature protect the reaction centre? 
How can we couple light harvesting with electron transfer, proton-coupled electron transfer?
How can we utilize theoretical analysis and prediction for designing systems?​

• Molecular catalysts for artificial photosynthesis

Crucial points for discussion are water oxidation, hydrogen evolution, and CO2 reduction catalysis:
What are the bottleneck subjects and how can we get through them? 
How can we get electrons from water for CO2 reduction?

• Inorganic assembly catalysts for artificial photosynthesis

Key points for discussion are visible light responsive semiconductors, polyoxometalates, organic/inorganic hybrid compounds:
How can we improve charge separation?
How can we reduce the effect of defect? 
How do hot electrons behave in the conduction band and how can we control the flow of the electrons?​

• Integration of systems for demonstrating realistic devices

Important points for discussion are systemization, coupling with solar cells, thermal decomposition of water by sunlight, energy payback time, cost payback time, science communication among general society:
How can we design, assemble, and integrate systems? 
What is the time schedule?
When will industry join?
How and when does the general public choose to adopt technologies?
