In my experiment I converted light into electricity using solar panels, which helped me learn how solar panels work.
In order to convert energy into electricity you have to use a method called the principle of photovoltaic conversion. According to Pavel Chrobak, this principle allows photovoltaic cells to convert light into electricity by releasing electrons. In my experiment I measured how electricity is produced when light was absorbed into solar panels. I collected data that shows how this principle works. In my experiment I learned that in order to convert light into electricity electrons have to be released. This can be done by using solar panels to turn sunlight into volts/power After I completed my experiment, I realized that I could probably have used the sun instead of lightbulbs. I could do this by measuring the power output of the sun at different times of the day. Next time I might try this to get a more exact understanding of how solar panels work. …show more content…
My experiment could have been better if the watts between the different light bulbs was more exact (20, 40, 60...). Also, my data results would have probably been more accurate if I had waited over a minute or more before measuring the voltage. I was worried the solar panel cells would overheat, since I had accidentally cracked one cell already, because I left the light on too long, so I measured the readings immediately. I could also add more solar panels to the experiment to see if I get a more consistent result. Lastly, I could switch my solar panel connections from a series circuit to a parallel circuit. This would change the power output from volts to amps.
I used the principle of photovoltaic conversion to test my hypothesis. According to Pavel Chrobak, this principle allows photovoltaic cells to convert light into electricity by releasing electrons. In my experiment I used different wattage lightbulbs to convert the light into electricity by releasing the electrons from the substrate (solar

hotline is, as Peak, Modest, and Spare. From 0 to 17, there are 18 numbers, hence we defined that, the numbers of calls received from 0 to 5 calls as a Spare time, from 6 to 11 it is Modest, and from 12 to 17 it is a Busy hour. Summing up the frequencies from 0 to 5, and further being divided by 7 days, staff answering very few phone calls are: (60 + 0 + 0 + 3 + 3 + 5) / 7 ≈ 10.14 employees This results indicates that in each day between Monday and Sunday, there are approximately 10.14 staff receives…

the yellow activates. The buzzer also cuts on and off at a frequency of 10 Hz. The alternation of on off for the buzzer is what actually generates the buzz instead of a single click. Since the voltage supplied from the Arduino pin is approximately 5 volts, I deemed the 300 ohm resistor to be sufficient. The photoresistor changes resistance when luminance is picked up. When the resistance is increased, the voltage drop changes because the current supplied is held…

Galileo signal plan is separated in major bands in which are broadcasted 10 different navigation signals. The Galileo E1-L1-E2 have a center frequency of 1575 MHZ with a code frequency 1.023MHz. band coincides with the GPS L1 band, but is wider. The E5 band is 92.07 MHz wide and centered at 1,191.795 MHz It is partitioned into E5a and E5b sub bands, with carrier frequencies of 1,176.45 and 1,207.14 MHz. The E5a sub band coincides with the GPS L5 band, while the E5b sub band overlaps the GLONASS L3…

(5) 2.These local means can be smoothed using moving average method to form a smoothly varying continuous local mean function. The envelope estimate is smoothed in the same way as the local means to get the the local envelope function. 3. Subtract the local…

The table below depicts that T4, T5, and T6 gave the lower mean number of branching points ranging from 17.55 to 26.77. Consequently, T2 which is the negative control had a higher mean number of branching points in the blood vessels of ducks CAM which is 52.10 As shown in the table, T6 which received the highest dose of 45µg/ml CLE exhibited the lowest mean branching frequency of blood vessels count which was 17.55. This was followed by the T5 with blood vessels count of 21.33 and T4 which has a…
