I MADE A BERRY CELL

HERE’S WHAT THE POWER PROFILE OF MY CELL LOOKED LIKE…

STEP 1

I PREPARED A WORKING ELECTRODE

  • I placed my ‘working electrode’ in a crystallising dish with crushed raspberries, making sure the entire white titania layer was covered in berry juice.

  • And I left it to soak in the berry juice for a few minutes.

STEP 2

I prepared the ‘counter electrode’

  • With a pencil I coloured the conducting side of the glass with graphite.

  • And I added a spacer and some electrolyte.

STEP 3

I ASSEMBLED THE BERRY CELL

I assembled the Berry Cell after rinsing and drying the working electrode.

STEP 4

I TESTED MY BERRY CELL

  • It produced a few milliwats of power, which is enough to replace 2 coin cells a year.

  • The most efficient 'Berry Cells' (dye-sensitised solar cells) can replace around 100 batteries every year. The average British person uses around 10 batteries every year.

STEP 5

 


I CERTIFIED MY RESULTS

  • I pressed the big red Berrybutton and got a sticker to certify that my Berry Cell is working!

I TWEETED MY RESULTS

  • The yellow line with squares shows how much current the cell produced.

  • The purple line with circles shows the power under different loads.

  • Maximum power is what we always want to use.
