in this paper, the performance evaluation of a two-way hybrid photovoltaic/thermal (pv/t) solar collector was analytically and experimentally carried out. mathematical expressions for operating parameters in glass to glass and glass to tedlar pv/t solar collectors were developed and experimentally validated by a glass to tedlar pv/t solar collector system. also the influence of air flow rate on...

We demonstrated plasmonic effects in an inverted tandem polymer solar cell configuration by blending Au nanoparticles (NPs) into the interconnecting layer (ICL) that connects two subcells. Experimental results showed this plasmonic enhanced ICL improves both the top and bottom subcells' efficiency simultaneously by enhancing optical absorption. The presence of Au NPs did not cause electrical ch...

Colloidal CdSe quantum dots (QDs) of different sizes, prepared by a solvothermal route, have been employed as sensitizers of nanostructured TiO(2) electrode based solar cells. Three different bifunctional linker molecules have been used to attach colloidal QDs to the TiO(2) surface: mercaptopropionic acid (MPA), thioglycolic acid (TGA), and cysteine. The linker molecule plays a determinant role...

As a new-style solar cell, copper indium gallium selenide (CIGS) thin-film cell owns excellent characteristics of energy absorption, and it is one the widely used cells. This paper mainly focuses on research progress this type cell. Firstly, its theoretical principles are briefly described. Then, materials, configuration fabrication procedure introduced. Subsequently, remarkable work about CIGS...

Working paper developed for a NASA-sponsored study of solar cells Significance Part 6: Tutorials, textbooks and reviews Lightning interception by an unprotected building 30 feet high x 45 feet long on flat land, in the Cleveland area, can be estimated at one strike per 200 years on the average. However, peculiar configuration can easily affect this estimate upward or downward. Means are availab...

The design of an interface unit is described, in which RS232 serial data is converted to latched parallel data on 22 independent lines. The data direction of each line is programmable through the serial port. Two picocontrollers are employed in a parallel processing mode to give the required number of I/O pins, and data on the shared serial line is coded to separate data streams to the individu...

in the present study we focus on the effect of donor/acceptor composition on the conjugation and ordered structure of the donor-polymer in the most common organic solar cell based on a bulk heterojunction of regioregular poly(3hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM). In addition, we try to illustrate the effect of composition, over a wide range, on the inter...

We report observations of a relatively long period 3 He-rich solar energetic particles (SEPs) measured by Solar Orbiter. The consists several well-resolved ion injections. high-resolution STEREO-A imaging reveal that the injections coincide with extreme ultraviolet jets and brightenings near east limb, not far from nominal magnetic connection originated in two adjacent, large, complex active re...
