possible in multijunction solar cells by the insertion of selective photon reflectors at the back of each junction [7] but is more challenging than in single-junction cells because of the inacces sibility of the rear surface of all but the bottom junction. The keys to achieving these high efficiencies include: 1) use of multiple materials that span the solar spectrum, 2) growth of these materials with near-perfect quality by using epitaxial growth on single-crystal substrates, and 3) use of concentration. 0000285983 00000 n
These high efficiencies are possible due to the ability of stacking solar cells made of different III–V semiconductors. The efficiency of single-junction solar cell at standard test condition (STC) is 22 %. Multijunction and gallium arsenide solar cells weigh more than silicon solar cells and cost approximately five times as much per unit power at the cell level. This is over two times as efficient as a single junction solar cell. 0000284424 00000 n

High-efficiency multijunction devices use multiple bandgaps, or junctions, that are tuned to absorb a specific region of the solar spectrum to create solar cells having record efficiencies over 45%. Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials.Each material's p-n junction will produce electric current in response to different wavelengths of light.The use of multiple semiconducting materials allows the absorbance of a broader range of wavelengths, improving the cell's sunlight to electrical energy conversion efficiency. 0000288398 00000 n

Efficiency can vary with the amount of equivalent suns the cell is exposed to, the crystalline structure of the layers, and the structure of adjacent layers. Multijunction (MJ) solar cells achieve very high efficiencies by effectively utilizing the entire solar spectrum. A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
