Pv Module

Solar modules are being built with nearly the same configuration for decades now. The front is covered with a tempered glass pane. The performance of a PV module can be increased by the texturation of the front side. One of the major requirements for front cover glasses is their high optical transmission. One option to boost transmission is texturing the front surface in a similar manner to crystalline solar cell. Another advantage of a textured glass is the fact that the reflected light beam at normal incidence has a second chance of being transmitted to the solar cell. Furthemore, the texturation of front cover glass might collect more dust and soiling than a flat glass surface. Due to this concern, the soiling effect of module covered with textured cover Alberino P glass after long-term exposed will investigated in this work. The modules presented in this work have the same characteristics in STC (i.e short circuit current, open circuit voltage and maximum power point). Electroluminescence, I-V and P-V characteristic are the method used to detect faults on the PV module. The results show a loss of PV performance with textured cover glass is l,72% higher than the reference module in other hand the increase of serie resistance is also observed in both modules

Tracing Method

A flat-type concentrator for circular solar cells has been proposed to improve the performance for a conventional flat-plate module with perfectly circular and semi-square Cz silicon cells. Fundamental optical properties of various V-grooves for concentrator modules with circular cells are calculated using a ray-tracing method to optimize the shape of V-groove. Based on these results, yearly-integrated irradiance ratios of the concentrator to a conventional flat-plate module are calculated using meteorological data. By the use of a reflection material with a reflectivity of 94%, yearly-integrated irradiance ratio of an optimized light-trapping type concentrator (LTC) module with circular cells attains to 1.18. Suppose that the LTC module and a conventional module gain the same amount of irradiance, the area of solar cells in the PV module can be reduced to 84.7% compared with the conventional flat-plate module. A LTC module with semi-square solar cells is designed and simulated for module fabrication. Yearly-integrated irradiance ratio attains to 1.25 using a reflectivity of 80%. The area of solar cells in a PV module can be reduced to 80% compared with a conventional flat-plate module.

An examination of some specialized lunar and planetary ephemerides has revealed inconsistencies in the adopted planetary masses, the presence of non-gravitational terms, and some outright numerical errors. They should be considered of temporary usefulness only, subject to subsequent amendment as required for the interpretation of observational data.

Electron Microscopes

Solid state x-ray sensing systems have been used for many years in conjunction with scanning and transmission electron microscopes. Such systems conveniently provide users with elemental area maps and quantitative chemical analyses of samples. Improvements on these tools are currently sought in the following areas: sensitivity at longer and shorter x-ray wavelengths and minimization of noise-broadening of spectral lines. In this paper, we review basic limitations and recent advances in each of these areas. Throughout the review, we emphasize the systems nature of the problem. That is. limitations exist not only in the sensor elements but also in the preamplifier/amplifier chain and in the interfaces between these components.Solid state x-ray sensors usually function by way of incident photons creating electron-hole pairs in semiconductor material. This radiation-produced mobile charge is swept into external circuitry by electric fields in the semiconductor bulk.
