MULTIJUNCTION CELLS
1.
Single junction cells rely on photons whose
energy is equal to or greater than the
band gap.
2.
Multijunction cells consist of at least 3 cells
and at the most 10
3.
Placing several cells together allows the collectors
to catch a wider width of the band
gap, because they convert more of the
energy spectrum’s light into electricity.
3.
Typical Multijunction cell works by stacking
them one on top of the other. the top
cell contain the largest band gap and the
highest energy photons are absorbed. Photons
not absorbed in the first cell continue
on to the second cell, which absorbs
the higher-energy portion of the remaining
radiation.
