“…It can be observed that the PCE obtained for the AM1.5g spectrum is greater than that for the black body radiation spectrum, which is in agreement with the results reported in (Belghachi 2015), given that the bandgap of the analyzed perovskite E g =1.55 eV. PCE for cases where there are interference effects has pronounced maxima for certain thicknesses of the perovskite layer.…”

Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost photovoltaic modules. In this paper we have determined the ideal power conversion efficiency and quantum efficiency of PSCs with the p-i-n device structure, where p is the hole transport layer, i is the perovskite absorber layer, and n is the electron transport layer. The absorption of incident light occurs in a thin perovskite layer, the thickness of which is comparable to the wavelength of absorbed light. We take into account interference effects when the PSC structure is represented by a Fabry-Perot resonator. The optical flux within the absorbing layer is calculated as a function of the spatial coordinate (in the direction of the layer thickness), for a certain wavelength, at the normal incident light. The power quantum efficiency is calculated assuming that the incident light source is a blackbody at the temperature of the Sun, as well as for the AM1.5g standard solar spectrum. The results obtained by using the derived expressions that take into account the interference effects are compared with those obtained by neglecting these effects.

“…In previous studies [30][31][32], the conversion efficiency of solar cell is calculated by utilizing Shockley-Queisser theory. The previous results qualitatively consistent under a blackbody with temperature 6000K and AM1.5 standard, which have minor numerical differences because spectral power density have minor differences.…”

“…where E g is the bandgap of the absorber and N ph is the number of incident photon per unit area per unit time with energy above E g . At a first approximation, the N ph can be calculated using the Planck equation [23]. However, for a more reliable estimation, a common standard solar spectra model used as reference to allow comparison of solar cell models and devices is the air mass 1.5 global spectrum referred to as AM1.5G spectrum [24,25].…”

Using the Spectroscopic Limited Maximum Efficiency, and Shockley and Queisser predictor models, we compute the solar efficiency of the chalcopyrites AgMX 2 (M=In,Al; X=S,Se,Te). The results presented are based on the estimation of the electronic and optical properties obtained from first principles density functional theory as well as the many-body perturbation theory calculations. The results from this report were consistent with the experimental data.The optical bandgap was accurately estimated from the absorption spectra, obtained by solving the Bethe and Salpeter equation. Fitting the Tauc's plot on the absorption spectra, we also predicted that the materials studied have a direct allowed optical transition. The theoretical estimations of the solar cell performance showed that the efficiencies from the Shockley and Queisser model are higher than those from the spectroscopic limited maximum efficiency model. This improvement is attributed to the absorption, the recombination processes and the optical transition accounted in the calculation of the efficiency.
