Gold nanoparticles introduced ZnO/Perovskite/Silicon heterojunction solar cell

FIGURE 4.
 
Dependence of thef short-circuit current of the gold 
nanoparticles with radius of 6 nm and 11 nm introduced ZnO/Si solar cell 
on periodicity 
The minimum value of the short-circuit current of the 
ZnO/Si solar cell with a nanoparticle of 11 nm radius was 
equal to that of the ZnO/Si solar cell without the 
nanoparticle. The maximum value was 1.29 times greater 
than that of the ZnO/Si solar cell without the nanoparticle. In 
experiment [55], it was found that silver nanoparticles can 
boost efficiency of ZnO/Si heterojunction solar cell. In 
addition, the short-circuit current of the ZnO/Si solar cell can 
also be determined by formula 1. Figure 5 shows the 
dependence of the absorption coefficient of the ZnO/Si solar 
cell on the wavelength. The reason for the sharp decrease in 
the short circuit current of ZnO/Si solar cell with gold 
nanoparticle (dp=120 nm, r=6 nm) is the sharp decrease in 
the absorption coefficient in the wavelength range of 535-
900 nm. Its absorption coefficient is almost reduced from 
that of the ZnO/Si solar cell without nanoparticle.

cell on the wavelength 
Figure 6 shows the dependence of the open circuit voltage 
and fill factor of perovskite/Si and ZnO/Si solar cells on 
nanoparticle size and periodicity. The open circuit voltage of 
perovskite/Si (Fig. 6.a) and ZnO/Si (Fig. 6.a') solar cells also 
changed depending on the nanoparticle size and periodicity, 
as did the short-circuit current. For the perovskite/Si solar 
cell, the maximum value of the open circuit voltage was 
0.384 V, the minimum value was 0.366 V, and for the 
ZnO/Si solar cell, it was equal to 0.306 V and 0.27 V, 
respectively. The open circuit voltage of Perovskite/Si and 
ZnO/Si solar cells without nanoparticles is 0.3 V. Therefore, 
when a gold nanoparticle is introduced into a perovskite/Si 
solar cell, the efficiency increases significantly.
