Opis:: Availability of light to solar cells is crucial for the efficiency of photovoltaic systems. For this reason, even partial shading can result in significant reduction of generated electric power (loss of current). This paper examines the changes in the efficiency of multicrystalline silicon solar cells which are caused by different kinds of shading. Full and partial shading were simulated by the use of three types of shutter-foils printed in a gray and black scale. The measurements of current-voltage characteristics show that totally or partially shaded modules can drastically reduce the generated power. Short circuit current decreases from about 8100 to 100 mA that in the case of the series connection of cells in a module, lead to the shift of the point of the maximum power and finally to the considerable reduction of nominal system photovoltaic power.

Opis:: Eight organic dyes are used as sensitizers for dye-sensitized solar cells. These dyes are eosin Y, aniline blue, bromophenol blue, alcian blue, methyl orange, crystal violet, fast green, and carbol fuchsin. The absorption spectra of these dyes are carried out by UV–VIS spectrophotometry. Dye-sensitized solar cells are assembled using nanostructured, mesoporous TiO2 films. Photovoltaic parameters of the fabricated cells are investigated and the highest overall conversion efficiency of 0.399% is obtained for the dye-sensitized solar cell sensitized with eosin Y.

Opis:: The rapid technological development necessitates the creation of increasingly new and more efficient solutions in photovoltaics, where the concept of perovskite solar cells is playing an ever-growing role. Perovskites, as an extensive and diverse group of chemical compounds characterized by a specific ABX3 crystal structure, exhibit exceptional electrical and optical properties, making them one of the most attractive groups for applications in modern photovoltaics. The following review article illustrates how the understanding of perovskite solar cells has evolved over the past decade. It emphasizes the significant role that scientists worldwide have played in addressing various challenges, such as the stability and durability of perovskites under harsh conditions. The research findings also highlight the importance of designing new perovskite compositions that exhibit increased stability and lower degradation rates. Scientists are also exploring innovative encapsulation techniques to protect the perovskite layers from environmental factors, which is crucial for ensuring their long-term performance. As a result of their research, there has been an improvement in the efficiency of solar energy conversion in modern cells, enabling them to compete with conventional silicon technologies, while the potential of tandem solutions presents new opportunities for their development.

Opis:: One of the crucial parameters affecting the solar cell efficiency is the absorption rate versus solar spectrum. Metallic nanoparticles deposited on the cell surface can mediate this process. Main mechanisms of absorption enhancement due to metallic nanoparticle plasmons were proposed: (1) the scattering of incident solar light causing increase of the optical path length inside active layer and local enhancement of the electric field; (2) near field coupling between plasmon and semiconductor and the direct generation of electron-hole pairs in the semiconductor. The field concentration effect can be described by classical electrodynamic theory, the coupling between metallic nanoparticle plasmons and band electrons in semiconductor substrate must be captured upon quantum mechanics. In this paper we took the challenge to develop fast and reliable method for calculation of device optical properties by application of COMSOL system appropriately configured to take into account these quantum effects, via the quantum modification of the dielectric function of semiconductor substrate and metallic components. The presented results indicate that the efficiency of energy transfer due to near field coupling of metallic nanoparticle plasmons with semiconductor substrate is much more effective than the absorption increase due to metallic nanoparticle plasmons scattering only.

Opis:: The nanoparticles of CH3NH3PbBr3 hybrid perovskites were synthesized. These perovskite nanoparticles we embedded in polymethyl methacrylate (PMMA) in order to obtain the composite, which we used as light converter for silicon solar cells. It was shown that the composite emit the light with the intensity maximum at about 527 nm when exited by a short wavelength (300÷450 nm) of light. The silicon solar cells were used to examine the effect of down-conversion (DC) process by perovskite nanoparticles embedded in PMMA. For experiments, two groups of monocrystalline silicon solar cells were used. The first one included the solar cells without surface texturization and antireflection coating. The second one included the commercial cells with surface texturization and antireflection coating. In every series of the cells one part of the cells were covered by composite (CH3NH3PbBr3 in PMMA) layer and second part of cells by pure PMMA for comparison. It was shown that External Quantum Efficiency EQE of the photovoltaic cells covered by composite (CH3NH3PbBr3 in PMMA) layer was improved in both group of the cells but unfortunately the Internal Quantum Efficiency was reduced. This reduction was caused by high absorption of the short wavelength light and reabsorption of the luminescence light. Therefore, the CH3NH3PbBr3 perovskite nanoparticles embedded in PMMA matrix were unable to increase silicon solar cell efficiency in the tested systems.

Opis:: The technology of manufacturing silicon solar cells is complex and consists of several stages. The final steps in succession are the deposition of antireflection layer and discharge contacts. Metallic contacts are usually deposited by the screen printing method and then, fired at high temperature. Therefore, this article presents the results of a research on the effect of heat treatment on the properties of the Al2O3 thin film previously deposited by the atomic layer deposition method. It works well as both passivating and antireflection coating. Moreover, heat treatment affects the value of the cell short-circuit current and, thus, its efficiency. The surface morphology, optical and electrical properties were investigated, describing the influence of heat treatment on the properties of the deposited layers and the manufactured solar cells.

Opis:: We tried to fabricate the Ge/TiO2 composite films with the differential pressure (pumping) co-sputtering (DPCS) apparatus in order to improve the optical properties. In the study, the micro structure of these thin films has been evaluated. TEM image revealed that the thin film was alternately layered with TiO2 and Ge, lattice fringes were observed both of Ge layer and TiO2 layer. There were portions that lattice fringe of Ge was disturbed near the interface of Ge and TiO2. X-ray photoelectron spectroscopy elucidated that there were few germanium oxides and a part with the thin film after annealed.
W pracy przedstawiono rezultaty badań mających na celu wytworzenie warstw kompozytowych Ge/TiO2 wykorzystując aparaturę do różnicowo-ciśnieniowego współrozpylania jonowego (DPCS) w celu poprawy właściwości optycznych. Mikrostruktura warstw została zbadana z zastosowaniem mikroskopii TEM. Analiza TEM wykazała, że cienki film składał się z naprzemiennie ułożonych warstw TiO2 oraz Ge, a dodatkowo zlokalizowano krawędzie sieci przestrzennych Ge i TiO2. Rentgenowska spektroskopia fotoelektronów wykazała niewielkie ilości tlenków germanu oraz występowanie cienkiego filmu po procesie wyżarzania.

Opis:: Organic solar cells have drawn intense attentions in recent years due to their inherent advantages. But the relatively low power conversion efficiency is the main obstacle in the way of organic solar cell commercialization. One of the main reasons that limit the power conversion efficiency is the mismatch between electrical transmission properties and light absorption properties in an organic active layer. In this work, a highly efficient light trapping scheme with a hybrid microlens array is proposed to resolve this contradiction. This structure can achieve broadband absorption enhancement in the spectrum of interest by chromatic aberration correction and hole parameter adjustment. And the light trapping element can be separated from cells to avoid direct contact with an organic layer that may cause electrical defects. Moreover, it is also compatible with low cost manufacturing technologies.

Opis:: Al₂O₃/TiO₂ thin films were deposited onto monocrystalline silicon surfaces using an atomic layer deposition. Their surface morphology and optical properties were examined for their possible use in solar cells. The surface condition and chemical composition were characterized using a scanning electron microscope and the thickness was measured using a spectroscopic reflectometer. The refractive index and the reflection characteristics were determined. First, the optical properties of the Al₂O₃ thin filmand its influence on recombination in the semiconductor were examined. In this way, it can fulfil a double role in a solar cell. Since reflection reduction was only achieved in a narrow range, it was decided to use the Al₂O₃/TiO₂ system. Thanks to this solution, the light reflection was reduced in a wide range (even below 0.2%).
