Solar panels are built with materials that physically interact with certain wavelengths of solar energy. This enables them to transform solar energy into electricity. Here’s how solar panels absorb and store energy. What’s in a solar panel? Traditional solar panels are made with silicon crystals. Silicon is a very special material.
When photons, particles of light, strike the solar cell, they can be absorbed if their energy matches or exceeds the band gap energy. Shorter wavelengths, such as UV and blue light, carry higher energy photons. Silicon solar cells are efficient at absorbing these shorter wavelengths.
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.
Silicon solar cells are efficient at absorbing these shorter wavelengths. Longer wavelengths, including infrared, carry lower energy photons and are less efficiently absorbed by silicon solar cells. Let’s delve into the physics behind it to understand solar cells’ spectral absorbance better.
But if you want to go a bit deeper into the process of how solar panels create electricity, we'll explain what you should know. Solar cells are typically made from a material called silicon, which generate electricity through a process known as the photovoltaic effect.
Instead, the solar panels, known as "collectors," transform solar energy into heat. Sunlight passes through a collector's glass covering, striking a component called an absorber plate, which has a coating designed to capture solar energy and convert it to heat.
