“…Nowadays, several ways of classifying the technologies for manufacturing photovoltaic cells exist, depending on the characteristics to highlight (thickness, efficiency, cost… etc). A typical classification will be made on the basis of the semiconductor element/s and of their thickness [17,18,19]. For that reason, the technologies are divided as follows: thin layer with tracking systems for solar concentration: based in alloys of III-V elements (the most common alloys are made by using the following elements: Al, As, Ga, In y P) these cells are very expensive, but since they are the most efficient, specially when using tandem technology and solar concentration and tracking systems, they can be cost competitive with the above mentioned technologies • A 5 : Manufacturing technology with advanced, low cost, thin layers (Organic and hybrid cells): two classes, hybrid technology based in inorganic TiO 2 network sensityzed with organic dyes and embedded in an electrolite; or the full organic solar cells based in polymeric layers offer the possibility of large cost reduction in the manufacturing process.…”

The aim of this paper is the study and analysis of the decision criteria to be used when searching for the best technology for manufacturing photovoltaic modules, considering both technical and non-technical criteria such as social and environmental factors. Multi-criteria decision making (MCDM) methods will be used for the modelling of the selection problem of the best technology for manufacturing photovoltaic cells. Combining these techniques with the use of fuzzy sets will mean that linguistic labels can be used to value the criteria used.

Abstract. With more penetration of solar power plants, photovoltaic generation will be exerting more influences on the power system. The main purpose of this paper is to study the dynamic characteristics of the power system with photovoltaic generation. First, power flow and bus voltage variations of the system with photovoltaic generation are calculated. Then according to the related interconnection criteria, the voltage variation and cable loading are inspected to determine whether the system complies with relevant specifications. Finally, the dynamic responses of the system are analyzed. This paper focuses on a sample power system with photovoltaic generation. The system dynamic characteristics are examined when three-phase faults occur, and the system voltage variations subject to illumination change are investigated. Results show that photovoltaic generation has less impact on system because the capacity of the photovoltaic generation is not high. The illumination change does affect both voltage and frequency of the system, and the system will return to a normal operating state after a period of time.

“…As a source of heat for thermoelectric generators (the thermoelectric method of thermal energy conversion into electric energy) involves unconventional renewable sources of thermal energy: from solar energy to the heat of human body. [1,2] Currently, for thermoelectric conversion of heat most widely used approach based on the Seebeck and Peltier effects created at the interface of two materials with different values S of the Seebeck coefficient. Such devices are commonly referred to as a thermocouple.…”

Enhanced spin figure of merit in a Rashba quantum dot ring connected to ferromagnetic leads Abstract. At room temperature we have investigated the transverse thermopower in thin single-crystal bismuth microwires for the purpose of using a microwire of bismuth to design an anisotropic thermoelectric generator.The singlecrystal nanowire samples in the diameter range 2 -15 μm were prepared by the high frequency liquid phase casting in a glass capillary using an improved Ulitovsky technique; they were cylindrical single-crystals with (1011) orientation along the wire axis. Bismuth microwire was placed between two polished aluminum plates, which were at different temperatures. At relative displacement of the plates the microwire was rotated around its axis. Transverse thermoelectric power varied by rotating microwires. The maximum thermoelectric power (S max ~ 200 -600 μV/K at the length of the plates L = 4.5 cm) occurred at the direction of the transverse temperature gradient along the C 3 axis. For the first time significant difference was found in the values of the thermoelectric power after turning micrwires at 180 degrees (i.e. when the direction of the temperature gradient is reversed). The value of this switching effect, defined by us as (||S max |-|S min ||) / (|S max |+|S min |), depends on the diameter d microwire and varies from 0.4 (for microwires with d = 14 μm) to 0.75 for microwires with d = 5 μm. Different assumptions about the nature of the observed effect will be discussed.
