Modelling of thin–film tandem solar cells
Numerical modelling of thin–film tandem solar cells is investigated using PC–1D program. The program is adapted to simulate the performance of multi–junction solar cells. Cadmium–zinc telluride (Cd0.6Zn0.4Te) is chosen as an absorber layer material for the wide band gap top cell and copper indium diselenide (CuInSe2) is chosen as an absorber layer material for the bottom cell in the whole tandem ...

The comparison of several silicon solar cells
The solar cell is also known as the "solar chip", it is a kind of photoelectric semiconductor wafer that works by solar energy. Solar energy refers to solar radiation energy. Since the formation of the earth, organism mainly light and heat, provided by the sun to survive, and as a method of food preservation, such as salt and salted fish. But nowadays, the application of solar energy gathered ...

Solar Cell Thin Film Analysers from Hiden Analytical
Solar cell thin film analysers are used to facilitate research and development (R&D) into novel photovoltaic architectures by monitoring the processing conditions for epitaxial deposition of photovoltaic materials. These growth methods cover a range of advanced techniques, such as plasma-enhanced chemical vapour deposition (PECVD) and radio frequency sputtering, which are used to generate a ...

In situ indium–induced crystallisation of low temperature nano–poly silicon (LTNPS) thin film on ITO glass substrate
For the first time, the low temperature nano–poly silicon (LTNPS) thin films were formed on indium tin oxide (ITO) glass with a temperature of ∼200ºC using the in situ indium–induced crystallisation of the plasma enhanced CVD (PECVD) deposited a–Si. Compared with the conventional method for transfer of the PECVD formed amorphous structure to the nano–poly one, the technology features a low ...

Transparent conducting oxides superstrate for thin film solar cells: an industrial prospective
The demand for a TCO coated glass substrate as a base material and front electrode of the solar cells is expected to grow very strongly in the next few years. Therefore it is crucial to prepare the industrial tools and proper glass compositions to meet this very impressive demand. Mass production of extra clear glass and atmospheric pressure thermal CVD tool installed directly on the float glass ...

Solar Cell Thin Film Analysers: The Basics
Global energy consumption is rapidly outstripping the available supply. When we factor in that over half of the world’s electricity is generated by non-renewables and that the global population growth remains incredibly high, concerns about the energy sector’s ability to provide for future generations seem well-founded. A gradual pivot towards renewables seems both inevitable and ...

Water vapour permeation measurement for PV Solar Cell packaging
With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries. As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies. At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter technology ...

Solar`s Time to Rise and Shine.
Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the photons ...

Nanoscale Research on Kilometre Scale Solar Panels
Now that solar energy has a larger share in our energy supply, it is becoming more important that solar panels are reliable and behave predictable. To be able to predict when solar panels will fail, insight into the failure mechanism is essential. This knowledge is used to improve the quality and longevity. Scientists at TNO Energy Transition and Solliance Solar Research have developed a ...

Record sales for solar PV cells in 2009
Manufacturers of solar PV cells produced 10,700 MW of product around the world in 2009, setting a new record, according to a recent Eco-Economy Indicators Report by the Earth Policy Institute (Washington, DC). The 10,700 MW represented a 51% increase over 2008 production levels—less than the dramatic 89% growth in 2008 but still continuing the rapid industry growth since 2004. As of the end ...

Solar Energy Advantages and Disadvantages
Electricity is essential to every household. But what happens to those households in remote areas where electrification on the grid is not possible? The off grid home solar power system becomes very important in providing electricity in such homes. It is a stand-alone photovoltaic system which offers a cost-effective means of delivering a facility for lighting and appliances in the rural homes. ...

Why Are Solar Lights for Pathways Superior to Alternative Lighting?
Public lighting isn’t something that’s thought about very often–we doubt you’re raving about how there’s a new light system with a Type V light fixture at your favorite park. But something as mundane as a pathway light can actually be quite marvelous, especially if the light in question is an outdoor solar pathway light. These kinds of lights are highly ...
