2. POLYMER-BASED SOLAR CELLS: For Dr.Peel Material Science By Carmen M.Thomas

3. WHAT POLYMER-BASED MEANS thin film polymer to change energy from the sun to electric current Materials –Donates electrons –Accepts electrons Two possible processes –Photosynthesis approach –Full organic approach Photosynthesis –Highly porous film –Electrolytes Full-Organic –Electron acceptor and an electron donor

4. THIN FILM (pros-cons) Problems –Present problem with high temperatures Highlights –Less costly than present options –Can make any size needed –Can change the shape and color –Light weight

5. USAGE EXAMPLES Cell phones –Recharge less often Houses –Less costly electricity(supplement) Portable radios and laptops
