Nanosolar Inc. Case Study Analysis Nanosolar is a start-up company and expects to be one of the first manufacturers to produce thin-film solar panels using copper indium gallium (di)selenide (CIGS) technology. Nanosolar is focused on selling a single type of thin-film Photovoltaic (PV) module called the “Nanosolar Utility Panel”. The utility panel is 50% less energy efficient than c-Si modules, but being 90% less expensive to produce.

I am taking solar cells to the Ellesmere Island, Canada. Ellesmere island is the third largest island in Canada and the 10th largest island in the world. It is Canada’s most northerly area that located in Nunavut and it is the most northerly island in the Arctic Archipelago. This polar
In this experiment, anthocyanin was extracted from organic mediums and explored to find which source of extraction contains the largest quantity of anthocyanin, and in turn generates the most power. Chromatography was used in this experiment to determine the amount and concentration of anthocyanin extracted from each source. Ethanol was used as the solvent in the chromatography, as well as the extraction catalyst. The purpose of this study was to determine which extraction medium for the photovoltaic pigment, anthocyanin, is the most effective at generating power in a Dye Sensitized Solar Cell (DSSC). Anthocyanin was chosen as the photovoltaic pigment because it has the appropriate chemical properties for organically dyed solar cells. Anthocyanin

Absorption Spectrum of Conjugated Dyes Bashar Baraz Lab Partners: whole class Physical Chemistry II 3/22/2015 Abstract: The highly conjugated system of the cyanine dyes makes it a very good compound in the development of more efficient solar cells. In this experiment, the maximum wavelength was measured for nine dyes using a UV-Vis spectrum. The result that were obtained agreed with Kuhn’s model for the less polarizable end groups such as 3,3 '-diethyloxadicarbocyanine and 3,3 '-diethyloxatricarbocyanine. That suggested that these two compounds were not as easy to polarize compared to the rest of the dyes. The rest of the dyes required the use of the empirical parameter α to provide more reliable predictions of the wavelengths. This was due to the highly polarized ends of the dyes which needed the adjustment of the parameter to get more accurate results. The series with the higher polarizable end groups’ absorbed higher wavelength light than the less polarized groups. This supported the idea of the one-dimensional box. Also, higher wavelength was determined to be associated with longer conjugated carbon methine chains between the Nitrogen atoms. Kuhn’s free electron model was very reliable for this system.
Positron Emission Tomography (PET) For many people activities of daily living are taken for granted, such as getting dressed and determining what to eat for breakfast, lunch and dinner. How about taking the necessary medications prescribed by a physician? These things are as natural as breathing for most people, but for some it can really be a chore; however, for a select group, just remembering what to do after waking up is the hardest thing in the world.
For this project, three solar water distillers were constructed. Distiller A was composed of a bowl, a sheet of plastic wrap, a cup, a rock, and a rubber band. Distiller B was made of an automatic, plastic pet food feeder, two sheets of plastic wrap, a container,
Luminescent Solar Concentrators Luminescent solar concentrators (LSCs) are devices for concentrating solar illumination for use in photovoltaics, with applications in a variety of other lighting purposes. Richard Lerner is credited with creating the original LSC in 1973, consisting of a solution of laser dye contained between two sheets of glass. However, his proposal was rejected by the National Science Foundation132. The first appearance of LSCs in the scientific literature is a proposal by Weber and Lambe (1976)133 who reported a ``planar solar collector utilising a luminescent medium to absorb radiation, which emits light at longer wavelengths for concentration onto a semiconductor solar cell ' '. They also compiled a list of the fundamental advantages to the LSC approach of solar concentration, namely: lack of solar tracking requirements, absorption of ambient light, reduced thermal load, and spectral narrowing of light, leading to the possibilities of spectral matching with coupled PV cells. In 1977 Goetzberger and
Surface attachment of the biological elements: Fiber Optic Sensor for bio-sensing has an important part which is to attach biological elements with the sensor surface. The easiest way for this is surface fictionalization for the biological elements coat. Aminosilane, Polylysine, and nitrocellulose or epoxy saline are being used in the case of glass silicon chips. This process can bond the biological agent some of its examples are fixed with layer by layer. Polymer coatings charge with the deposition. There are there the main ways for the chemical and physical entrap. Hydro gel is used most of the time is sol-gel. Silicate monomers of polymerization are generated with glassy silica.

They involve interdigitated fingers (IDT) to increase the edge coupling length. Also called as comb-drive device. This study involve fabrication of aluminium IDE because of it cost low and common electrode in biosensor technology. The design of IDEs consist of twin electrode which are arranged in a comb like finger structure between twin electrodes to form gap distance between electrodes as shown in figure 2. Technically, the IDEs structure is easy to fabricate, simple operation, ultra-sensitive and low cost is main point to develop of sensor for clinical application. In other word, IDEs sensor is expected to provide are better performance and ultrahigh sensitive and selective of biosensor detection in smaller gap sizes3.Literature review In multiple applications the interdigitated electrodes thin film are a useful tool for enhancing the analytical parameters and taking advantages of their inherent properties such as low cost & disposables, reusable, high fabrication resolution, high sensitivity, low reagent consumption as well as non-tedious pre-cleaning procedures Figure 3 shows the design structure of an IDE. There are two sets of electrodes are placed in the same plane to the substrate. Generally, it is referred to comb-drive device because it is shaped like tooth of combs. Figure 3: Geometric parameters of IDE structureIn this work, a sensor to evaluate sterilization processes with hydrogen peroxide vapor has been characterized. Experimental, analytical and
Large solar plants occupy a vast area of land and threaten wildlife because one square kilometer is needed to produce 40 megawatts of energy from solar power.4 British scientists are attempting to improve the effectiveness of photovoltaic cells by utilizing “copper indium diselenide and cadmium telluride to find an affordable and more sustainable way to make solar panels to convert light energy into electricity.”5
