6 FAQs about [Multi-junction solar cell conversion efficiency]

How efficient is a multijunction solar cell?

A team of researchers of the Fraunhofer Institute for Solar Energy Research (ISE, Freiburg) and AMOLF (Amsterdam) have fabricated a multijunction solar cell with an efficiency of 36.1%, the highest efficiency ever reached for a solar cell based on silicon.

What is a multi-junction solar cell structure?

Multi-junction solar cells structure is multi-layers of single-junction solar cells on top of each other. Band gap of the materials form the top to the bottom going to be smaller and smaller. It allows to absorbs and converts the photons that have energies greater than the bandgap of that layer and less than the bandgap of the higher layer.

What is the output current of a multijunction solar cell?

The output current of the multijunction solar cell is limited to the smallest of the currents produced by any of the individual junctions. If this is the case, the currents through each of the subcells are constrained to have the same value.

How do multi-junction solar cells work?

Multi-junction solar cells consist of some single-junction solar cells stacked upon each other, so that each layer going from the top to the bottom has a smaller bandgap than the previous, and so it absorbs and converts the photons that have energies greater than the bandgap of that layer and less than the bandgap of the higher layer .
