Description
Technical field
The present invention relates to area of solar cell, more particularly, to a kind of DSSC Ag8GeS6To electrode
Preparation method.
Background technology
In recent years, with increasingly serious, the dye sensitization as one of third generation solar cell technology of energy problem
More concerns that solar cell is subject to, and with assembling, simple, cost is more low excellent than traditional silica-based solar cell
Gesture.Typical dye-sensitized cell is made up of three parts, including light anode, electrolyte and to electrode, forms traditional three
Mingzhi's structure battery.Light anode is mainly made up of TiO 2 porous layer absorption N719 dye molecules, when sunshine irradiation
When, N719, which absorbs sunshine, to be inspired electronics and is passed to external circuit by TiO 2 porous layer.The master of electrolyte
It is to restore dyestuff and transmission electric charge to want function.After dyestuff discharges electronics in absorption photon, electrolyte must provide as soon as possible
Electronics, by the reducing dyes in oxidation state to middle condition.Now widely used is liquid electrolyte, by redox
I-/I3 -Electricity forms to, organic solvent and additive.Preferably should possess following condition to electrode material：(1) there is high electricity
Muonic catalysis activity, beneficial to catalysis I3 -Ion reduction is into I-；(2) resistance of electronics transfer is small；(3) in the environment of electrolyte, tool
There is good electrochemical stability.What is be currently widely used for is the electro-conductive glass that surface is coated with one layer of platinum to electrode, and due to platinum
The influence of the factors such as cost, abundance and the long-time stability of metal, limit large-scale industrialization application.Therefore, substitute expensive
Metal platinum turns into an important job in the application of field of dye-sensitized solar cells.
Up to now, researcher is prepared for a series of non-platinum to electrode material, such as carbon material
