How specific and measurable should a PhD research objective be‑ Can an objective be too detailed?

I'm an Engineering PhD student. My objective is "To improve the efficiency of solar cell design." My supervisor said it's too vague, but I'm worried that being too specific like "To increase efficiency by 2.3%" will box me in if I can't hit that exact target.

In Engineering, objectives must be quantifiably measurable, but the metric can be comparative or methodological, not just a numeric target. Instead of a vague "improve" or a rigid "2.3%," frame it as: "To design and fabricate a novel multi-junction solar cell architecture and evaluate its efficiency gain against industry-standard silicon cells under AM1.5 illumination." This objective is specific (multi-junction architecture, specific benchmark), measurable (efficiency gain will be evaluated), and flexible (it doesn't pre-judge the result). The action is "design, fabricate, and evaluate." The outcome is a measured comparison. This gives you a clear success criterion (you conducted the evaluation) without boxing you into an arbitrary performance number you can't control. Objectives should define the task and the standard of assessment, not guarantee an exact outcome.
