In this process, incident light stimulates the oscillation of conduction electrons at interfaces containing metal nanoparticles or nanostructures of subwavelength size.
Q5. What is the effect of g() at higher wavelengths?
Further absorption enhancement g(λ) is decreased at higher wavelength range with an increment of TiN nanparticles diameter above 110 nm.
Q6. What is the effect of the plasmonic nanoparticle on the absorption of light?
If the plasmonic nanoparticledeposited between the air-glass interface then preferential scattering would be into the glass due to its higher refractive index [52, 53].
Q7. What is the effect of the higher order mode excitation on the absorption of light?
The further increment of metal nanoparticle size, higher order mode excitation will take place, which light scatter can enhance or decrease the light trapping efficiency into the substrate depending upon the order of modes excited [22, 44, 45, 13, 48].

The insights in this paper suggest that TiN can be a potential plasmonic material for thin film photovoltaics, Visible and infrared applications and optoelectronics.
Q9. What is the effect of interference between incident and scattered light?
In addition, destructive interference between incident and scattered light are not in phase which results the reduction in absorption enhancement.
Q10. What is the absorption enhancement g() of a metal nanoparticle?
The absorption enhancement g(λ) with the optimum size of the metal nanoparticle 100 nm in their case, the forward scattering efficiency of the particle enhances due to the excitation of quadrupole resonances.
Q11. How big is the cross-section area of the metal nanoparticle?
It is well known that around 100 nm size of spherical plasmonic nanoparticles usually having the large cross-section area of scattering.
Q12. How can the absorption enhancement peak be tuned to the desired position of the solar spectrum?
The absorption enhancement peak can be tuned to the desired position of solar spectrum by adjusting the size of TiN nanoparticles.
Q13. What is the effect of the antireflection effect on the silicon nanoparticles?
Besides this antireflection effect, constructive interference between the directly transmitted light at the Silicon interface and reradiated or scattered incident light by the nanoparticles when they are in phase which also results the absorption enhancement [16, 20, 54, 55].
Q14. What is the absorption peak of TiN nanoparticles?
Meanwhile the absorption peak red-shifts and also broadening in wavelength range with the increment of TiN nanoparticle diameter from 40 to 200 nm.
Q15. What is the absorption enhancement spectrum for the solar cell?
The absorption enhancement spectrum g(λ) for the wavelength range 300 nm to 1100 nm as written as follows;g (λ) = QENP (λ) QEbare (λ) = PNP (λ) Pbare (λ) (3)g was calculated for each nanoparticle diameters simulated via the computation of quantum efficiencies.
Q16. What is the effect of LSPR scattering on thin film solar cells?
In this paper, the authors numerically studied how the plasmonic material TiN nanopar-ticles influence the light trapping and absorption enhancement in thin film silicon solar cells.
Q17. What is the effect of the interference between an incident and scattered light?
In addition destructive interference between an incident and scattered light are not in phase and also parasitic absorption of higher order resonance modes [38, 42, 43].
Q18. What is the absorption of TiN nanoparticles in the near infrared?
In Figure 2, it can also observe that in the near infrared wavelength range, the absorption peaks are enhanced which influenced by forward scattering effects due to LSPR [36, 38].
