LED Band Gap & ColorLive
590 nm
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.

Wavelength590 nm
Regionvisible
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.

Governing equation

Reading this result: A 4.0 kW array in 5-sun-hour sun yields about 19.2 kWh/day — roughly 0.7 average homes.

Frequently asked questions

What is the Photovoltaic Physics multi-solver?
Photovoltaic Physics is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
Is it free to use?
Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
