2.10 eV band gap

Controls

Presets

An LED emits light when electrons drop across the semiconductor's band gap, each releasing a photon of energy equal to that gap. Since photon energy fixes wavelength (λ = 1240/Eg in nm), the band gap directly sets the color — which is why blue LEDs needed a whole new material (gallium nitride) and a Nobel Prize to achieve.

MaterialGaP/AlInGaP (green-red)

Governing equation

Reading this result: λ = 1240/Eg puts this 2.10 eV gap at 590 nm — a wider gap means a bluer photon, which is exactly why blue LEDs needed the high-gap GaN family.

Presets

A solar array's output is its rated power (area × efficiency at 1000 W/m²) multiplied by the peak sun hours your location receives — the equivalent full-intensity hours per day. Tilt matters too: aiming the panels near your latitude maximizes annual yield. Real systems lose a bit more to heat, wiring, and inverters.

About this simulation

The full Photovoltaic Physics tool models a bouncing ball with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
