“…When the efficiency of a porous one-dimensional (1D) SiO 2 /TiO 2 photonic-crystal-coupled ZnO-Pt dye-sensitized solar cell was investigated, it was discovered that the required integrated system allows for optimal absorption in the selected spectrum area (i.e., 400-900 nm), resulting in a maximum efficiency of 4.5% for a ZnO-Pt dye-sensitized solar cell with a 1D SiO 2 /TiO 2 photonic crystal [24].…”

“…The value of V oc can be obtained from Eq. 16, which is as follow [50,51] V oc = ln (16) Where, K B , T, e, and J o represent Boltzmann's constant, room temperature, electron charge, and reverse saturation current (dark current), respectively. As the bandgap widens, J sc drops while V oc widens.…”

We propose a highly efficient, low-cost metamaterial absorber of nickel (Ni) metal-based cone-shaped resonators with a silicon dioxide dielectric layer (SiO2). The proposed absorber exhibits an average absorption of 97% for the transverse magnetic (TM) and transverse electric (TE) modes over the visible region which is simulated by CST software. The nickel-metal impedance coincides with the impedance of free space and makes the proposed design an effective broadband absorber in the visible region. The average absorption with different incidence angles obtains over 90% and shows the polarization angles' independence. The average absorption spectra are also examined for the absorber with different noble metals. In addition, short-circuit current densities (Jsc) are calculated at different incidence angles for both modes under a global air mass of 1.5 (AM1.5). We have also plotted the J–V curve to obtain the values of the open-circuit voltage (Voc), Fill Factor, and conversion efficiency (η), whose values are 0.563V, 81.86%, and 11.68%, respectively. The proposed metamaterial absorber can be utilized to develop more reliable, highly efficient, cost-effective, and maximum-power extraction photovoltaic systems.

“…While DSSCs have unique advantages, their lower absorption of incident light by sensitizer dye molecules, accompanied by recombination of photo-generated charge carriers at the photoanode-electrolyte interface, limits their power conversion efficiency (PCE). Several modifications to the structure of DSSCs have thus been researched to improve light harvesting and reduce recombination reactions, raising their PCE [9][10][11][12]. Optical modifications, like reflective layers, enhance light harvesting by reflecting unabsorbed photons back into the photoactive layers, recycling them into the system [13].…”

Dye-sensitized solar cells (DSSCs) hold unique promise in solar photovoltaics owing to their low-cost fabrication and high efficiency in ambient conditions. However, to improve their commercial viability, effective, and low-cost methods must be employed to enhance their light harvesting capabilities, and hence photovoltaic (PV) performance. Improving the absorption of incoming light is a critical strategy for maximizing solar cell efficiency while overcoming material limitations. Mesoporous silica nanoparticles (MSNs) were employed herein as a reflective layer on the back of transparent counter electrodes. Chemically synthesized MSNs were applied to DSSCs via bar coating as a facile fabrication step compatible with roll-to-roll manufacturing. The MSNs diffusely scatter the unused incident light transmitted through the DSSCs back into the photoactive layers, increasing the absorption of light by N719 dye molecules. This resulted in a 20% increase in power conversion efficiency (PCE), from 5.57% in a standard cell to 6.68% with the addition of MSNs. The improved performance is attributed to an increase in photon absorption which led to the generation of a higher number of charge carriers, thus increasing the current density in DSSCs. These results were corroborated with electrochemical impedance spectroscopy (EIS), which showed improved charge transport kinetics. The use of MSNs as reflectors proved to be an effective practical method for enhancing the performance of thin film solar cells. Due to silica’s abundance and biocompatibility, MSNs are an attractive material for meeting the low-cost and non-toxic requirements for commercially viable integrated PVs.
