SOLAR CELL PROJECT: GADGET RESCUER Team of Tom Craven, Ahyeon Yoo, Nuri Kim, Rhys John, and San LeeModule: Balancing Studies


PROJECT BRIEF

Design a Product/System which will utilize solar energy through the use of solar cells. This Product/System should be efficient and effective at harnessing the suns power and storing it in a way that makes it easy to use.

The Product/System should be suitable for use within a range of applications such as mobile phones, I Pads, mp3 players and cameras and therefore should interact with such products with ease.

The Product/System should incorporate a Service that is aimed at people who require a power boost for portable electronic devices whilst out and about.

The Product/System should be aesthetically pleasing, a product that will be desirable and will stand out as a thing of beauty and not just another generic solar panel.

How the Solar panel technology works

Converting Photons to Electrons The solar cells that you see on calculators and satellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in one frame). Photovoltaics, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house. How do these devices work?

Photovoltaic (PV)cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductormaterial. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. For example, the current can power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.

TECHNICAL INFORMATION



The latest cutting edge materials

At the heart of Konarka’s technology is a photo-reactive polymer material invented by Konarka co-founder and Nobel Prize winner, Dr. Alan Heeger. This proprietary material can be printed or coated inexpensively onto flexible substrates using roll-to-roll manufac-turing, similar to the way newspaper is printed on large rolls of paper.

Power Plastic is thin, light-weight and flexiblePower Plastic is comprised of several thin layers: a photo-reactive printed layer, a transparent electrode layer, a plastic substrate and a protective packaging layer. Power Plastic can be manufactured up to 60” wide in virtually any length – and panels can be combined for greater power output.

Compared to the manufacture of traditional silicon-based solar panels, Konarka offers several advantages:Significantly lower cost for new plant constructionLower manufacturing energy costExisting facilities can often be retrofitted at much lower cost.

Total Energy Collected During morning hours, Power Plastic begins collecting energy earlier.

During midday hours, Power Plastic energy collection increases at a faster rate, due to our superior thermal coef!cient.

Power Plastic continues to collect energy later in the day, while others “"atline”.

MATERIALS

Solar panel materials Materials currently used for generating electrical power in solar panels include:-

Mono-crystalline SiliconHigh performance but has structural integrity issues. Has an efficiency of 17%. Internal use required so not to be damaged.

Polycrystalline SiliconHigh end products only as very expensive to produce. Can be used to make thin film, micro/macro.

Amorphous SiliconLots of uses within a variety of electric powered applications. Can be made really thin to save on material cost. Good all-rounder

Microcrystalline SiliconA mix between Mono-crystalline and Amorphous Silicon. Captures blue light. More efficient than other solar materials when no direct sunlight is falling on them.

Cadmium SiliconThe cheapest of solar panels are made from this. Cadmium is very rare to the Earth and will one day be exhausted, it is also toxic to humans in dust form.

Copper Indium Gallium Selenide Efficiency of 10% - 15%. Very strong light absorbency! 1-2 micrometers will absorb most sunlight.
