The present study deals with the effect of the presence of cylindrical aluminum nanoparticles on the parameters of short circuit current density and absorption in the active layer of ITO/PEDOT:PSS/P3HT:PCBM/ZnO/Al organic solar cell by means of the Finite-Difference Time-Domain (FDTD) method. The nanoparticles are located in a hexagonal pattern inside the P3HT:PCBM layer and on its border with ZnO. During the simulation, the AM1.5 standard sun spectral pattern has been used in the spectral range of 300-1200 nm. Calculations have shown that the presence of nanoparticles causes a considerable improvement in the values of the parameters. This increase is especially noticeable in the range of high wavelengths. Given the results, when the nanoparticle height is changed, the optimal thickness is also changed, where the short circuit current density and the absorption have the highest values, in a way that at the heights of 50, 100 and 150 nm for nanoparticles, the P3HT:PCBM layer is optimal in the thicknesses of 150, 200 and 250 nm. These results are independent of the radius of nanoparticles. Comparison of calculation results in different conditions shows that both the short circuit current density and the absorption will have the highest values for 150 nm thickness of P3HT:PCBM layer and for nanoparticles with 50 nm height.

“…Resonant architectures have the potential to promote a more efficient light incoupling and increased optical path length at specific wavelength values, when compared with the microscale approach. Here, configurations such as periodic gratings, [128][129][130] plasmonic NPs, [70,[131][132][133][134][135][136][137][138] and dielectric nanostructures [70,[139][140][141] are included. Morphology-dependent light scattering and/or localization can be achieved through schemes exploiting resonant photonic or plasmonic effects.…”

[41,70,[131][132][133][134][135][136][137][138]141] Plasmonic architectures present additional benefits, as compared with the typical periodic mesoscale gratings.

“…Further improvements on the used light-trapping architecture are required, as Au or Ag NPs with smaller dimensions can provide a higher scattering performance, when compared with Mo spheres. [138,146,148,222] Nonetheless, Au and Ag will diffuse during the high-temperature absorber growth, if not properly encapsulated. [43,65,70,148,191] One of the proposed architectures uses a TCO rear contact to encapsulate the metallic NPs.…”

Light management strategies are of utmost importance to allow Cu(In,Ga)Se2 (CIGS) technology market expansion, as it would enable a conversion efficiency boost as well as thinner absorber layers, increasing sustainability and reducing production costs. However, fabrication and architecture constraints hamper the direct transfer of light management architectures from other photovoltaic technologies. The demand for light management in thin and ultrathin CIGS cells is analyzed by a critical description of the optical loss mechanisms in these devices. Three main pathways to tackle the optical losses are identified: front light management architectures that assist for an omnidirectional low reflection; rear architectures that enable an enhanced optical path length; and unconventional spectral conversion strategies for full spectral harvesting. An outlook over the challenges and developments of light management architectures is performed, establishing a research roadmap for future works in light management for CIGS technology. Following the extensive review, it is expected that combining antireflection, light trapping, and conversion mechanisms, a 27% CIGS solar cell can be achieved.

“…Computational simulation, or also called in-silico experiments, has become widely accepted as "Third Pillar of 21 st Century Science", along with theory and experimentation. Within this framework, the CIGS technology has used accurate and efficient optical and electrical simulations to better understand and overcome the complexity of the CIGS solar cell system and for orientation through novel research directions [7][8][9][10][11][12][13][14] . To extend the CIGS understanding from the thin to an ultrathin thickness range, while maintaining the performance of the solar cell, optical and electrical simulations play a key role on understanding the difference in several phenomena, such as, light propagation, interface scattering, and carrier dynamics.…”

One of the trends making its way through the Photovoltaics (PV) industry, is the search for new application possibilities. Cu(In,Ga)Se2 (CIGS) thin film solar cells stand out due to their class leading power conversion efficiency of 23.35 %, flexibility, and low cost. The use of sub-µm ultrathin CIGS solar cells has been gaining prevalence, due to the reduction in material consumption and the manufacturing time. Precise CIGS finite-difference time-domain (FDTD) and 3D-drift diffusion baseline models were developed for the Lumerical suite and a 1D electrical model for SCAPS, allowing for an accurate description of the optoelectronic behavior and response of thin and ultrathin CIGS solar cells. As a result, it was possible to obtain accurate descriptions of the optoelectronic behavior of thin and ultrathin solar cells, and to perform an optical study and optimization of novel light management approaches, such as, random texturization, photonic nanostructures, plasmonic nanoparticles, among others. The developed light management architectures enabled to push the optical performance of an ultrathin solar cell and even surpass the performance of a thin film solar cell, enabling a short-circuit current enhancement of 6.15 mA/cm 2 over an ultrathin reference device, without any light management integrated.
