Description
Technical field
The utility model relates to solar cell.
Background technology
Perovskite since two thousand nine starts to be used to solar cell.Perovskite solar cell not only has the feature of first generation solar cell height transformation efficiency, also has the feature of third generation solar cell film, flexibility, can be used for solwution method volume to volume and produces.
Perovskite battery (PVSK) is a kind of organic-inorganic compoiste, take MAPbX3 as light absorbent, coordinates the novel solar battery of electronics and hole mobile material.Thickness before its encapsulation only has several microns, and be far thinner than the conventional films such as amorphous silicon, CIGS solar cell, cost is also only 1/3rd of other silicon solar cell assembly.
But in traditional perovskite battery production, because perovskite contains lead, plumbous have harm to human body and environment.
Summary of the invention
1, technical problem to be solved:
Containing lead human body and environment being had to harm in the solar cell of perovskite structure.
2, technical scheme:
In order to overcome the above problems, the utility model provides a kind of solar cell of tin perovskite structure, is followed successively by electro-conductive glass, TCO anode, electron transfer layer, tin perovskite absorbed layer, hole transmission layer, silver from top to bottom.
TCO anode is zinc oxide.
Electron transfer layer is titanium oxide electron transfer layer.
The thickness of described tin perovskite absorbed layer is 300-500 nanometer.The thickness of described tin perovskite absorbed layer is 350 nanometers.
3, beneficial effect:
The solar cell of the tin perovskite structure that the utility model provides, perovskite is replaced to do absorbed layer with tin perovskite, the solar cell of tin perovskite energy structure at utmost absorbs visible ray in solar spectral and part infrared light, do not need heating just can directly melt simultaneously, replace with tin plumbous, decrease plumbous use, this tin perovskite structure solar cell, stable chemical nature and preparation process are simple, effectively reduce the cost of manufacture of battery, reduce plumbous use.
Accompanying drawing explanation
The structural representation of the solar cell of Fig. 1 perovskite structure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of solar cell of tin perovskite structure, is followed successively by electro-conductive glass, TCO anode, electron transfer layer, tin perovskite absorbed layer, hole transmission layer, silver from top to bottom.Wherein TCO anode is zinc oxide, and electron transfer layer is titanium oxide transport layer.
The thickness of described tin perovskite absorbed layer is 300-500 nanometer.The thickness of described tin perovskite absorbed layer is 350 nanometers.
Electronics is transferred to the electron transfer layers such as titanium oxide from tin calcium titanium ore bed, is finally collected by electro-conductive glass, and hole is transferred to hole transmission layer from tin calcium titanium ore bed, is finally collected by metal electrode.
The solar cell of the tin perovskite structure that the utility model provides, perovskite is replaced to do absorbed layer with tin perovskite, the solar cell of tin perovskite energy structure at utmost absorbs visible ray in solar spectral and part infrared light, do not need heating just can directly melt simultaneously, replace with tin plumbous, decrease plumbous use, this tin perovskite structure solar cell, stable chemical nature and preparation process are simple, effectively reduce the cost of manufacture of battery, reduce plumbous use.
The solar cell of tin perovskite structure of the present utility model can as solar module: the multiple solar cells utilizing the utility model to produce, by going here and there and connecting, and vacuum pressure-bearing, produce as solar module, by the string of solar module also, composition photo-voltaic power generation station.
The solar cell of tin perovskite structure of the present utility model can as at solar lawn lamp: the solar-electricity tank discharge utilizing the utility model to produce, coordinates energy-storage battery, be applied to solar lawn lamp, street lamp etc.
Although the utility model with preferred embodiment openly as above; but they are not of the present utility model for limiting; anyly have the knack of this skill; not departing from the spirit and scope of the utility model; can make various changes or retouch from working as, what therefore protection range of the present utility model should define with the claims of the application is as the criterion.
