How does a thin sheet of glass and silicon turn sunlight into electricity, with no moving parts, no fuel and no noise? In this animated explainer, we follow a single ray of sunlight from the Sun all the way to the socket in your wall.

You'll learn:
☀️ Why light is made of photons, and why color matters
🔬 What makes silicon a semiconductor (and what the band gap is)
⚡ How N-type and P-type doping create the P-N junction
🔋 The photovoltaic effect: how electrons are pushed into a current
🏠 How cells become panels, and how inverters deliver AC power to your home
📉 Why panels are ~20–23% efficient, and how tandem cells beat 33%
