Student Guide (IB Design Technology)

Simple Explanation: Even though we've learned a lot about using sunlight to split water, we still need more basic science work to make these devices good enough to sell.

Why This Matters: This shows that innovation isn't just about building something new, but also about understanding and solving the deep problems that stop new ideas from becoming real products.

Critical Thinking: To what extent should a design project prioritize fundamental scientific breakthroughs versus immediate engineering solutions for market entry?

IA-Ready Paragraph: The development of solar-driven water-splitting devices, as highlighted by McKone, Lewis, and Gray (2013), necessitates a strong foundation in basic research to address inherent design constraints. Their perspective underscores that while progress has been made, significant challenges remain before commercial viability can be achieved, emphasizing the need for continued exploration into critical research areas and device components.
