The figure below presents the EQE of a triple junction solar cell with junctions A, B and C under short circuited (V = 0 V) condition.
a) What is the bandgap (in eV) of the absorber layer of the junction A?
b) What is the bandgap (in eV) of the absorber layer of the junction B?
c) What is the bandgap (in eV) of the absorber layer of the junction C?
d) Which of the following statements is TRUE?
1)Junction C acts as the top cell, Junction B as the middle cell, and Junction A as the bottom cell.
2)Junction B acts as the top cell, Junction C as the middle cell, and Junction A as the bottom cell.
3)Junction A acts as the top cell, Junction B as the middle cell, and Junction C as the bottom cell.
Each junction is illuminated under standard test conditions. Given the photon fluxes below, calculate the short-circuit current density (in mA/cm2) of each (separate) junction (A, B and C):
ϕ=9.3∗1020m−2s−1 for 300nm<λ<650nm
ϕ=8.4∗1020m−2s−1 for 650nm<λ<850nm
ϕ=1.4∗1021m−2s−1 for 850nm<λ<1250nm
e) Jsc of Junction A:
f) Jsc of Junction B:
g) Jsc of Junction C:
h) The Voc of each junction in V can be roughly estimated by the equation
Voc=Egap(J)2q=Egap(eV)2
where q is the elementary charge, Egap(J) is the bandgap energy expressed in Joules, and Egap(eV) is the bandgap energy expressed in eV. Assume a fill factor of FF=0.75. What is then the efficiency (in %) of the triple junction solar cell?

To find the answer is pretty simple. E= h*c/λ*q
Where,
h is the planck's constant
c is the speed light in vacuum
λ is the wavelength
q is the elementary charge
