How Do Tandem Structures Work?

The fundamental working principle of tandem structures is based on the combination of materials with different bandgaps. By layering materials with different bandgaps, tandem structures can capture a broader spectrum of light or energy. For instance, in solar cells, a tandem structure might include a top layer that absorbs high-energy photons and a bottom layer that absorbs lower-energy photons. This allows for more efficient energy conversion than a single-junction device.
