Solar Photovoltaic Cell Basics

Multijunction solar cells can reach record efficiency levels because the light that doesn''t get absorbed by the first semiconductor layer is captured by a layer beneath it. While all solar cells with more than one bandgap are multijunction solar cells, a solar cell with exactly two bandgaps is called a tandem solar cell.

A roadmap for tandem photovoltaics

Considering these requirements, several materials could make good top cells for a tandem. III–V absorbers (e.g., GaAs and GaInP) have the highest power conversion efficiency (PCE) of single-junction devices and are components of high-efficiency multijunction solar cells. Their main drawback is the high cost of fabrication.
