“…Both methods have been widely used to simulate the optical properties of artificial subwavelength nanostructures and are in good agreement with the experiment [42][43][44]. In addition to the bionic moth eye structure, researchers have designed a series of artificial nanostructures with good antireflection effects, including nanowires [45,46], nanocones [47,48], nanoholes [49,50], nanopyramids [51,52], and some complex composite structures [53,54]. Micronanomanufacturing technology is the key to realizing that artificial antireflection nanostructures can be applied to silicon solar cells.…”

Due to the ongoing depletion of fossil energy, alternative energy-sources and their respective conversion technologies have become very essential. An inexhaustible and clean energy form, which is already widely used, is solar energy. However, despite much progress in recent decades, due to the limitations of materials and manufacturing technology, the ability of solar cells to convert light into electrical energy is still not very high. Enhancing light absorption and reducing electric loss are the keys to improving the overall conversion efficiency of solar cells and reducing raw material costs. The former can be achieved by using micro/nanostructures and other surface features, while the latter can be realized by surface passivation. Researchers have developed different silicon-surface texturing methods to fabricate random or periodic micro/nanostructures on the surface of silicon wafers. Thanks to the special and efficient light-trapping effects of silicon micro/nanostructures, both full angle and wideband light absorption can be achieved. Different passivation methods and materials have also been widely studied, which helps to improve the surface recombination of photogenerated carriers caused by light trapping structure and significantly enhance the power conversion efficiency of Si solar cells. In this work, theoretical studies of enhanced light-trapping in micro/nanostructures are introduced. In addition, several advanced methods for preparing micro/nanostructures on the surface of monocrystalline silicon are discussed. These can be classified as top-down and bottom-up approaches. Furthermore, passivation methods for micro/nanostructures on the surface of monocrystalline silicon solar cells are reviewed, including chemical passivation and field-effect passivation. Finally, advantages and disadvantages of the micro/nanostructure preparation technologies, and light-trapping effects of the micro/nanostructures, which were fabricated using these manufacturing technologies were summarized. Moreover, the effects of different passivation technologies on the optical properties and electrical properties of these micro/nanostructures are studied. An outlook of expected and emerging research directions for monocrystalline silicon solar cells concludes this study.

“…Such materials described by non-ideal band edges with significant density of states ,this materials including the presence of tail states(shallow trap states)extending into the bandgap.the tail states have some charactristics like trap depth and density that effect on the devive performance of organic solar cells devices [12][13][14].for example charge trapping into any state effect on charge transport and inc rease recombination.To enhance the absorption of the PM6:Y6 active layer, plasmonic nanoparticles (NPs) and refractory metals play an important role to boost the PCE of OSCs [11][12][13][14][15][16][17][18][19][20]. The most used Plasmonic NPs in literature were gold (Au) and silver (Ag) embedded into one of the OSC layers like the active layer [21][22][23][24][25][26][27][28][29][30][31]. Refractory metals like TiN have good properties that affect the performance of OSCs, which have chemical and heat stability at high temperature s, and they have a high melting point [15].…”

Organic solar cells (OSCs) are characterized by their low cost, flexibility, compact size, and solution processing. OSCs are created utilizing a nontoxic technology that employs bulkhetrojunction (BHJ) structures. The photo conversion efficiency (PCE) of OSCs has been boasted in the last decades. BHJ fullerene-based OSCs have low open-circuit voltages and poor photo absorption. In this study, the recent non-fullerene acceptor (Y6), which has an electron-deficient core-based central fused ring, has been used. The promising PM6:Y6 material is used as an active layer in the proposed OSCs. The light trapping of the OSCs is enhanced by embedding plasmonic nanoparticles (NPs) in one of its layers. This could be a long-term approach to collecting more light in the photoactive layer. Au and Ag NPs have been employed the most in plasmonic OSCs. They improve PCE due to their plasmonic properties, strong localized surface plasmonic resonance (LSPR) in the visible region of the light spectrum, on-toxicity, and oxidation resistance, although Ag NPs are prone to oxidation. However, they have high costs and thermal instability. Alternative plasmonic materials such as refractory metals with high melting temperatures exceeding 2000°C and high thermal and chemical stability are employed in this work holding a comparative study between them.

The present study is focused on investigating the mechanical properties of hybrid polymer composites. The reinforcement materials are animal bone (ox) particulate and E-glass fiber. The matrix material is epoxy resin. The following combinations are considered for investigation: (a) bone particulate weight percent (20%, 30%, and 40%), (b) E-glass fiber weight percent (20%, 30%, and 40%), and (c) bone particulate (10%, 20%, and 30%) and E-glass fiber (30%, 20%, and 10%) with epoxy resin 60% by weight percent. The test specimens are prepared as per the required ASTM standard for tensile, compressive, and flexural tests. The test results show that maximum tensile and compressive strength observed in 40% of E-glass fiber with 60% of epoxy matrix, correspondingly, is 254.964 MPa and 37.52 MPa. The maximum flexural strength observed in E-glass fiber reinforced composites is 250.43 MPa.
