DIY染料敏化太阳能电池(图解)
|
||||
|
１．We start with 2 glass plates. Each plate is coated with TCO (or Transparent Coated Oxide). This is a thin coating which is electrically conducting in much the same way as metal wire. The TCO consists of SnO2:F (:F indicates that the tin oxide is doped with a very small amount of Fluor). The coating is transparent to enable light to pass through without loss. Doping is the process where small quantities of foreign atoms are introduced to control the electronic properties of semi conductors. The function of the TCO is to transport the current produced from the solar cell to the power consuming device. The Minus electrode goes by the name of ‘Photo electrode”  ２．A thin layer of TiO2 is coated on the photo electrode. This layer consists of a spongy 3 dimensional nano crystalline network. The layer itself has a thickness of 10 micrometer and is randomly stacked. Nano technology lies at the heart of this type of solar cell. The TiO2 particles are ‘grown’ from around 3 nm to approx. 20 nm which appears to be the most optimal size for this type of dye solar cell.  3.The dye molecules attach to the TiO2 particles.  4. The plus or counter electrode is provided with a thin graphite layer. The purpose of the graphite is to act as a catalyst.  5. The electrolyte is added. The electrolyte consists of Iodine (I2) and Sodium Iodide (NaI) dissolved in ethanol.  [ Last edited by leotron23 on 2006-8-23 at 18:45 ] |
