Q

What is the photoconductive effect?

🔍 Key Concepts

• Photon as a packet of light energy • How light affects the electrical properties (resistance/conductivity) of semiconductors • Difference between creating voltage and changing conductivity

💭 Think About

• When light hits a semiconductor, what happens to the number of charge carriers (electrons/holes)? Does that make it easier or harder for current to flow? • Which options describe making electricity from light (like a solar cell), and which describe just changing how well something conducts? • If something is called photoconductive, focus on the meaning of the word: what does photo- mean, and what does -conductive refer to?

✅ Before You Answer

• Identify which choices describe conversion of energy (light to electricity or electricity to light) versus change in conductivity. • Decide whether illumination should logically cause more or less conduction in a photoconductive material. • Make sure the chosen option matches the idea of a material whose resistance changes when exposed to light.
