Dependence of the absorption coefficient of a perovskite/Si 
solar cell on wavelength 
According to the result presented by Figure 1.b, the short-
circuit current of the ZnO/Si solar cell in the range of 
nanoparticle radius (9 nm, 21 nm) varies according to the 
exact law depending on the periodicity of nanoparticles. 
However, in the range of nanoparticle radius (4 nm, 9 nm) it 
was found that it does not obey the rules. Therefore, Figure 
4 shows the dependence of the short-circuit current of a 
ZnO/Si solar cell with a nanoparticle with a radius of 6 nm 
and 11 nm on the nanoparticle periodicity. The short-circuit 
current of a ZnO/Si solar cell with a size of 11 nm 
nanoparticles varied periodically depending on the distance 
between the nanoparticles, like a perovskite/Si solar cell. 
There was an unusual shift in the short circuit current at 6 nm 
of nanoparticle size. With a separation of 120 nm between 
nanoparticles, the short circuit current drops to 2.13 mA/cm
2
. 
It was found that the short-circuit current of the ZnO/Si solar 
cell without nanoparticles was 8.11 mA/cm
2
. Hence, when 
gold nanoparticles with a size of 6 nm were introduced into 
a ZnO/Si solar cell with a periodicity of 120 nm, the short 
circuit current decreased by a factor of 3.81.
