 How you tackle a problem.

I have been doing research work all week on a very interesting topic name Dye Sensitized Solar Cells (DSSCSs) which is a photovoltaic cell that is environmentally friendly, sustainable and produces no CO2 emission. A DSSCs is considered good if can produces at least 1.4 Volts of electricity per cells (Kakiage et al, 2016). So, all this week I was trying very hard to tackle a problem of coming up with a method to make a working DSSCs that works right to produce electrical energy to power up a mini motor or an LED. The method had to be easy enough for anyone to do and even high school students that I am going to be teaching. My situation was to come up with my own method to make a working DSSCs. So, I spent lots of time on researching and read about many types of information and ideas available on the world wide web about making a working DSSCs. I gained knowledge about DSSCs from many researchers in forums on researchgates.com, journal articles in science direct, google scholar and watching YouTube videos. A working DSSCs had to produce at least 0.100 Voltage and most efficient produced over 1.4 Voltage per cells. My first task is to come up with my own method to make a working DSSCs from any components that are available at home, local supermarkets, and hardware stores. I thought it be difficult because I never knew that DSSCs can be made from house items such as fruits, veggies juices and ingredients in cosmetics products. So, I list down all the components already available in household items, laboratory, and local supermarket. Action, my instinct told me to use google to search up research by researchers/scientists to find out about any methods to make a working DSSCs and see if the components I have in the laboratory can be used. The reason why I decided used to google to search was because I can perform a search from any locations, allows to saved time and information about making a working DSSCs, which can be seen in some YouTube videos and some websites; just by typing into the search box/tab “do-it-yourself” dye sensitized solar cells. My alternate option to not using google to search would be to look up books in the Macquarie university library. I would have to go to the library to find books that show in detail how to make a working DSSCs, if it is where convenient to do so. So, as a result of my successful google this week, I was able to make my own method for making working DSSCSs, which is truly my own method because I am a scientist. The experience this week taught me that with google search I could find information about anything when brainstorm DSSCs topics such as solar power, natural dyes, and electrolytes. I discovered many websites and read about many interesting research about DSSCs because the world wide web is full of information. I felt such fascinated by DSSCs after using google to search due to it being simple and easy to find any information about DSSCs that kept me reading on and I grew in interest from anywhere I was.

How to make a working Dye Sensitized Solar Cells (DSSCs) Methods:

1. Measure the side of the FTO/ITO glass for conductance with a multimeter.

2. Use the cotton pads/swabs to clean the conductive glass plates with acetone, only touch the edges/sides.

3. Make the TiO2 paste using the demineralized water or white vinegar turn into a goo.

4. Apply plastic stick tape to the conducting side of the FTO/ITO glass plate.

5. Paste evenly thin layer of TiO2 paste using a spoon/glass rod on the conducting side of the FTO/ITO glass plate.

6. Now bake it onto a hotplate/cooktop for 20 to 25 minutes at 225 degrees Celsius to anneal the TiO2 paste on to the FTO/ITO glass plate.

7. Crush the berries in a plastic bag/mortar pestle.

 8. Pour the berries juice onto the side of the FTO/ITO glass plates with the annealed TiO2 layer, leave for 45 minutes.

9. Then rinse off excessive berries juice with water (be gentle).

10. Then rinse with ethanol to remove any residue of berries juice chemicals (dry in air).

11. Now built a layer of soot on the none conducting side of the other FTO/ITO glass plate using the graphite/lead pencils.

12. Use cotton pads/swaps/Kim wipes to remove excess soot.

13. Apply the iodide/iodine solution onto the glass plate with the anneal TiO2 plus Dye and then place the other glass plate clip together using 2 binder clips/alligator clips.

14. Place a multi meter clip on each end of the glass plates to measure its conductance.

15. Attach dye sensitized solar cells to mini motor or LED to see it working right
