0:00:00my name is bayes advantage you in my project is titled portable charger case then
0:00:05found and you know technology
0:00:07solar energy is defined as radiant light and heat from the sun that's harness using
0:00:12a range of technologies such as solar heating solar thermal electricity solar architecture and artificial
0:00:17for the synthesis in sp triple low solar suitable takes
0:00:21right now let me us the primary source of electricity school utilized feeling about thirty
0:00:27nine percent of electric production
0:00:29during a production carbon dioxide a greenhouse gas no for tracking he is released into
0:00:34the air
0:00:34although called accounts for only eighteen percent of also feel usage in the us it
0:00:39counts for thirty one percent of carbon dioxide emissions these greenhouse gases are primary cost
0:00:45for climate change and extreme weather conditions the temperature anomaly or deviation from the average
0:00:51from nineteen o one to twenty twelve in forty eight states of the us is
0:00:55shown in this graph
0:00:56as one can see the average temperature and one year has progressively gone up starting
0:01:00around the nineteen eighties solar panels on the other hand provide a clean source of
0:01:05electricity without emissions that lead to climate change
0:01:08a solar panel is an electrical device that converts light energy usually from the sign
0:01:12directly into electricity like from the centres absorbed by the panel and it excites electrons
0:01:17in the semiconductor which then produce and direct electric current sometimes in burgers are included
0:01:23to change the current to an alternating current
0:01:26the difference between types of solar panels lie in the semiconductors
0:01:29traditional solar panels use chris on silicon
0:01:32you semiconductors make the panels rigid you have a range of thickness is in a
0:01:36range of efficiencies highest recorded efficiencies for these kernels and the forty percentile then some
0:01:41solar panels range from two hundred fifty eight hundred microns that flexible and you that
0:01:46scratch as easily as traditional panels
0:01:48the incorporation of nanotechnology a new branch of technology utilizing the manipulation of atoms and
0:01:54molecules
0:01:55in solar panel research
0:01:56is a new one upcoming thing
0:01:58according to come up on engineering news northwestern has been researching pair of skis cells
0:02:03which utilise calcium tiny and order to increase efficiency of solar panels while keeping both
0:02:08prices and thickness down in only one here the efficiency percentage of these cells has
0:02:13increased from one percent to sixteen percent for my experiment i just a test crybaby
0:02:17cells
0:02:18because of price availability and toxicity
0:02:21cell phones are then the fastest adopted piece of technology and the world in the
0:02:25us according to the pew research centre the percentage of american adults the on the
0:02:29cellphone in two thousand four close to sixty five percent and in twenty thirteen it
0:02:34was recorded to be ninety one percent
0:02:36it just fifteen to fifty four thing to have the highest percentage of adulthood cell
0:02:40phones
0:02:41looking at the breakdown of demographics
0:02:43the current model for solar panel case on the market is called that you timed
0:02:47movie as
0:02:48in case is probably kristen's telecon as a semiconductor
0:02:51for my project michael's were to create both a regular thin film based phone case
0:02:56and that in some case that you realise carbon for higher efficiency rate
0:03:00i also wanted my keys to be efficient then and cheap to make
0:03:06for my experiment i set up for solar powered phone cases ten centimetres away from
0:03:10a twenty while bold in order to control the environment
0:03:13to the case is that you realise kristen's solar panels remote controls
0:03:17the first is that you time will be s
0:03:18we just say before uses probably crystalline
0:03:21as a semiconductor
0:03:23is that can control case uses monica still and bass solo piano that is connected
0:03:27in parallel with the found in order to charge
0:03:29it to experimental some cases i made consisted of three ten times solar panels connected
0:03:33in parallel
0:03:34the carbon based one
0:03:35han additional layer
0:03:37one being carbon and grapheme sheets and the topping in the in turn oxide plastic
0:03:42that acted as an electrode experiment contained one trial with checkups every fifteen minutes
0:03:46over the course of four hours and fifteen minutes and one over the course of
0:03:50an hour
0:03:52the result of my controls over the four and fifty minutes setting are shown below
0:03:56in percentage versus time graphs
0:03:58e time will be is the case currently on the market should very poor results
0:04:02a phone kept running on and off
0:04:04second control the case utilizing monarch response telecon was pretty successful it was the only
0:04:09case had a positive correlation between percentage and time over the four hour and fifteen
0:04:13minute period
0:04:15well my experimental cases had a negative correlation between percentage in time but they also
0:04:20boasted a better job of keeping the phone on the case currently on the market
0:04:24although the carbon be sell did not and charge the phone as expected it at
0:04:28the phone on for longer than the regular panels which shows that the incorporation nanotechnology
0:04:32in solar panels is something that needs to be research more in order to increase
0:04:36efficiency of then from solar panels and solar panels in general
