Embedded metal nano-tube and textured silicon wafer reduces the optical loss of solar cell

Abstract: The objective of this work is to study the reflectivity and absorption of silicon wafer in respect of efficiency of solar cell. The efficiency of solar cell can be increased, by minimizing the optical loss of solar light. The study is carried out in two parts: in the first part, Lumerical FDTD solution software is used to find out the reflectivity of textured silicon wafer with antireflection coating. In the second part, physical surface texturization of silicon wafer has been done with a new recipe of NaOH and IPA in different percentages and ratios. In the first part of work, it is observed that the platinum nano-rod also improves the expected phenomenon of higher absorption of light in the range of 300–900 nm wavelength. The reflectance can be brought down to 17–19% in comparison with plain silicon substrate 30–35%. The absorption of light is also increased 80–82% in comparison of 44–65%. In the second part, mono-crystalline silicon wafer of 0.7 Ω to 3.5 Ω has been textured with 1% NaOH and 5% IPA in a temperature of 85 °C with the duration of 88 min, which shows the reflectance of 13% in newly textured silicon wafer. The reflectance of textured surfaces is optimized and validated with the result of FESEM.

Synthesis, characterization and photovoltaic studies of 2,2′;6′,2ʺ-terpyridine-based ruthenium complexes with phenylamino, anthranyl and furfuryl substitutions at the 4′-position

Abstract: A series of two heteroleptic ruthenium complexes of the type [Ru(X-tpy)(bpy-COOH)(NCS)](PF6) (where X-tpy = 4′-(4-N,N-dimethylaminophenyl)-2,2′:6′,2ʺ-terpyridine for complex 1 and 4′-(9-anthryl)-2,...

Hybrid Quantum Cloning Machine

Abstract: In this work, we introduce a special kind of quantum cloning machine called Hybrid quantum cloning machine. The introduced Hybrid quantum cloning machine or transformation is nothing but a combination of pre-existing quantum cloning transformations. In this sense it creates its own identity in the field of quantum cloners. Hybrid quantum cloning machine can be of two types: (i) State dependent and (ii) State independent or Universal. We study here the above two types of Hybrid quantum cloning machines. Later we will show that the state dependent hybrid quantum-cloning machine can be applied on only four input states. We will also find in this paper another asymmetric universal quantum cloning machine constructed from the combination of optimal universal B-H quantum cloning machine and universal anti-cloning machine. The fidelities of the two outputs are different and their values lie in the neighborhood of ${5/6} $

Two Party Non-Local Games

Abstract: In this work we have introduced two party games with respective winning conditions. One cannot win these games deterministically in the classical world if they are not allowed to communicate at any stage of the game. Interestingly we find out that in quantum world, these winning conditions can be achieved if the players share an entangled state. We also introduced a game which is impossible to win if the players are not allowed to communicate in classical world (both probabilistically and deterministically), yet there exists a perfect quantum strategy by following which, one can attain the winning condition of the game.
