有助于了解染料敏化太阳能电池的原理和制备过程.
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”
