Leave it in the berry juice to soak for 5-15 minutes. The longer you leave the cell in the dye, the better it will work! https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/4e93d005-280c-4c92-901d-c362d10835c0/films2.jpg How to Make a Berry Cell - PREPARING THE WORKING ELECTRODE Take 2 or 3 raspberries and put them in the crystallising dish. Using a spatula or glass rod, crush the raspberries to release the berry juice. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/d7faf4f6-b3c4-435e-ad20-bb37605cc769/electrolyte.jpg How to Make a Berry Cell - ADDING THE IODINE SOLUTION (ELECTROLYTE) Using a pipette, take up a small amount of iodine solution. Place 2 drops of iodine solution on top of the spacer on your working electrode. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/de15725e-24ef-4308-a8a9-f600e32b074f/paint.jpg How to Make a Berry Cell - Preparing the ‘counter electrode’ Use a pencil to colour in the conducting side of the glass. Be sure to cover all of the conducting side of the glass in pencil. Once you’ve done this, carefully remove the tape cover from the glass slide. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/b42e89a4-69b3-47ad-a167-c7852755a36a/spacer.jpg How to Make a Berry Cell - ADDING THE SPACER Place a spacer of tissue paper on top of the coloured-in glass. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/936edbe7-ee00-40a3-84ac-7128a9b2693c/wash1.jpg How to Make a Berry Cell - REMOVING WORKING ELECTRODE FROM DYE BATH Use tweezers to lift the ‘working electrode’ out of the dye bath, being careful not to scratch the titania layer. Rinse any excess dye from the working electrode by dipping it in the water beaker. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/52414798-8727-4838-b19e-bd6556f00070/assem1.jpg How to Make a Berry Cell - ASSEMBLING THE BERRY CELL Take the counter electrode and place it graphite side down on top of the working electrode, so that the graphite and the dyed titania are touching. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/acae9705-861e-4f45-ac0e-ff35145fcca0/comp2.jpg How to Make a Berry Cell - DRYING THE WORKING ELECTRODE Gently pat the glass slide with a paper towel to dry it. Don’t rub the glass slide as this will remove the titania layer. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/3f7d6d52-81bc-47b2-ab9a-95566ea8bdd1/press.jpg How to Make a Berry Cell - IMPORTANT! The position of the slides should be slightly offset (as in the photo) as this will allow you to connect crocodile clips in the next step. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/b3a7e485-541b-4d49-a5e5-3d35b5c97a81/measure1.jpg How to Make a Berry Cell - TESTING THE BERRY CELL Once you’re happy with the position of the slides, carefully place a crocodile clip on each side of the long edges of the cell to hold it together. ‘W’ to working electrode and ‘C’ to counter electrode. Once your Berry Cell’s connected, you can test it by pressing the red Berrybutton. https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/968bb830-8974-4ab9-bade-ac8219a5a906/comp.jpg How to Make a Berry Cell - GETTING YOUR RESULTS If it’s working correctly, it should print a sticker with the Current-Voltage Characteristics and the Power Output ! https://images.squarespace-cdn.com/content/v1/625e9ceb6b414b0ba4d9d1ef/069e1cfb-6e70-4851-b337-027d2f40114c/twitter.jpg How to Make a Berry Cell - CONFIRMING YOUR RESULTS Use the QR code to see your tweet!
