The Journey of Sunlight Photons to Electricity. Solar power starts with sunlight hitting materials like CdTe in solar panels. CdTe is popular because it''s cheap to make. When sunlight hits these materials, it turns into an electric charge. This is how we get solar power. Fenice Energy uses this process to bring cheap, clean energy to rural India.
Transistors are smaller, cheaper and consume less power and generate less heat. That means you can pack them closer together. Transistors can also be etched directly on a wafer of silicon, meaning you can manufacture a single chip with billions of transistors connected together.

Think of a ball at the top of a hill: It can move from the top to the bottom while spontaneously releasing energy, but some other process must provide the energy to take it from the bottom to the top. And this analogy provides a basic explanation for why a diode conducts in one direction, but not in the other.
