Therefore, high-efficiency solar cells will have a substantial economic advantage over low-efficiency solar cells, as the cost of fabricating the former is low enough. Additionally, efficiency improves the environmental impact of photovoltaic modules as less materials are needed to produce them.
Multi-junction solar cells are capable of absorbing different wavelengths of incoming sunlight by using different layers, making them more efficient at converting sunlight into electricity than single-junction cells.

Many MJ photovoltaic cells use III–V semiconductor materials. GaAsSb-based heterojunction tunnel diodes, instead of conventional InGaP highly doped tunnel diodes described above, have a lower tunneling distance. Indeed, in the heterostructure formed by GaAsSb and InGaAs, the valence band of GaAsSb is higher than the valence band of the adjoining p-doped layer. Consequently, the tunneling distance dtunnel is reduced and so the tunneling current, which ex…
