“…Measurements and details are given in separate publications; hence, we mentioned only some of the details of interest. Testing of the WFL system was conducted in parallel on several solar cells: four commercial ones (monocrystalline Si, KXOB22-01X8F and KXOB22-12X1F, and amorphous Si, AM-5907 CAR and AM 1816 CA solar cells [35][36][37][38][39] ), as well as some of the laboratory-made solar cells, differently designed Sb 2 S 3 -based solar cells based on synthesized undoped and doped Sb 2 S 3 nanomaterials, [16,36,[39][40][41][42][43][44] and dye-sensitized solar cells (Dyesol/Greatcell Solar DSL 30 NRD-T). [45] As artificial light sources, tungsten lamps (ULTRA-VITALUX 300-280), halogen lamps (Osram ELH 120 V 300 W), and xenon lamps (Newport 91 160 solar simulator) were used, while outdoor tests were conducted in July with the sun's rays falling vertically on the solar cell and the WFL system.…”

The basic function of the water flow lens (WFL) system is to cool, decrease, and increase light intensity with inevitable spectral oscillations, but in reality, that manipulation helps to better understand the possible additional optical and light effects and, thus, the nature of light itself, in the hopes of making significant progress toward the use of solar energy. According to the published research on a variety of solar devices, including commercial monocrystalline and amorphous Si‐solar cells, differently designed Sb2S3‐based solar cells made of synthesized undoped and doped semiconductors, and dye‐sensitized solar cells (Dyesol/Greatcell Solar DSL 30 NRD‐T) with varying sensitizers and cosensitizers, photovoltaic performance using the WFL system can show significant improvements in all tested conditions. Based on all previous results on different solar devices, many potential explanations for demonstrating common extra‐light effects for an increase in the performance of solar cells are experimentally compared and discussed. The theoretical history of the nature of light is reviewed, and our findings are commented on along with new disclosure.

“…On the other hand, the truth is that in the indoor environment, the spectral composition deviates greatly from AM 1.5, which can be seen in Figure 1b, 16 where the deviations in their spectra are more than evident. In all our previous publications, 15–17,57–62 it has been seen that even tiny differences in the spectrum have quite a pronounced and improved influence, primarily on current, voltage, and efficiency, and these observations included our designed Sb 2 S 3 ‐based, dye‐sensitized, and silicon cells. As a result, the different spectra of each of these lamps, which “well simulate outdoor radiation,” can have a significant impact on photovoltaic performance.…”

The operating characteristics of a commercial monocrystalline and amorphous Sisolar cell for outdoor and indoor applications with and without the use of the water flow lens (WFL) system are explored and reported. The cells are tested in indoor conditions with halogen and tungsten lamps, and additionally, in outdoor sun radiation.Changes in the spectra, investigation of the influence of higher and lower lighting, and indirect cooling of the solar cell are possibilities in the application of the used WFL system. After achieving the highest level of development and improvement for the Si-solar cell, as well as approaching theoretical maximum efficiency, it is obvious that efficiency gains can be made by better understanding additional light effects.

“…Furthermore, in our case, films for use in solar cells were created through redispersion and deposition of synthesized nanoparticles. Because of this process, it is possible to combine modifications of the same material with different bandgaps and tunable electronic characteristics or combine this semiconductor with conductive polymers or dyes as absorption layer composites, thus expanding the range of useful photons by the absorbing layer [20,21,24,27,32,33].…”

Amorphous non-doped and Se-, Cu-, and Zn-doped Sb2S3 nanoparticles prepared by a hot-injection method: bandgap tuning and possible observation of the quantum size effect

The modified hot-injection method was applied for the synthesis of amorphous non-doped and copper (Cu) and selenium (Se) doped antimony (III) sulfide (Sb2S3) nanoparticles with reduced sizes. Moreover, zinc (Zn) doped Sb2S3 nanoparticles were synthesized for the first time by the same approach. High-resolution transmission electron microscopy (HRTEM) and TEM of amorphous undoped and doped samples revealed small spherical nanoparticles of a few (1-4) nanometers aggregated into larger spherical clusters, while introducing different dopant ions into the Sb2S3 structure did neither influence the spherical morphology nor the sizes of samples. The presence of the basic elements (S and Sb) and dopants (Cu, Se, or Zn) was confirmed by EDX analysis and mapping. Additionally, field emission scanning electron microscopy (FE-SEM) was performed on the Zn-doped Sb2S3 sample, confirming spherical morphology as well as quantitative incorporation of Zn in the Sb2S3 lattice. X-ray powder diffraction (XRPD) results of the non-doped and doped samples revealed an amorphous structure. The crystalline Zn-doped Sb2S3 samples obtained by heating the amorphous ones revealed well-defined peaks from only the Sb2S3 phase, confirming a successful doping process. Diffuse reflectance spectroscopy (DRS) revealed high optical bandgap energies (2.03-2.12 eV) in comparison to the values (1.6-1.7 eV) obtained for large spherical non-doped and doped particles. It was demonstrated that there is not only a significant reduction in particle size compared to previously synthesized non-doped and doped amorphous nanoparticles of the same composition, but that there is also a significant increase in the bandgap values of 0.4-0.5 eV, which could be attributed to a quantum size effect. X-ray photoelectron spectroscopy (XPS) measurements revealed pure phase composition without any impurities for the undoped sample, and characteristic peaks for copper 2p, selenium, and zinc Auger peaks for the doped samples, respectively. The XPS valence band measurements were performed due to the weak Zn Auger peak, confirming a shift towards lower binding energy compared to the non-doped sample, demonstrating the doping of the observed sample.Photoluminescence (PL) measurements show that embedding Zn into the Sb2S3 host lattice suppresses the wide luminescence band with peaks at 1.7 eV, 2.0 eV, 2.2 eV, and 2.4 eV, which is related to intrinsic defects. Furthermore, the energy dependence of the light emission on the size of the synthesized nanoparticles suggests that the quantum confinement effect causes the light emission.
