Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is physical structure three-view diagram of the present utility model.
Fig. 2 is electrical connection diagram of the present utility model.
Embodiment
As depicted in figs. 1 and 2, constitute the plate condenser close with conventional photovoltaic battery unit 1 geomery by pole plate 1, pole plate 26, dielectric substance 5, be connected with lead 8 between photovoltaic cell unit sensitive surface electrode 2 and the capacity plate antenna pole plate 26, be connected with lead 7 between photovoltaic cell unit shady face electrode 3 and the capacity plate antenna pole plate 1, form the novel photovoltaic cell unit that the conventional photovoltaic battery unit is in parallel with plate condenser, i.e. a utility model.
After the conventional photovoltaic battery unit completes, make a capacitor according to the principle of plate condenser at its back side, plate condenser is made of three parts: intermediary dielectric materials 5, each capacitor plate 4 and 6 of both sides.Production order is: the plate condenser material that cutting is close with photovoltaic cell cell configuration size, cover a capacitor plate 4 close with photovoltaic cell cell configuration size at the back side of photovoltaic cell unit earlier, and the electrode backlight 3 of photovoltaic cell unit is electrically connected with it, cover the dielectric 5 of plate condenser again, for making capacitance enough big, preferentially select high dielectric constant materials such as conjugated polymer, heterojunction etc. for use, make another piece capacitor plate 6 at last and make it and link to each other with photovoltaic cell unit sensitive surface 2 electrodes.Be attached to the back side of photovoltaic cell unit again after three parts of plate condenser of also can completing earlier and be electrically connected.Like this, just made successfully a kind of novel photovoltaic cell unit with the energy storage capacity plate antenna, wherein photovoltaic cell is in parallel with capacity plate antenna.Its operation principle: after aforesaid a plurality of photovoltaic cell unit strings are unified into an assembly, produce electric power after receiving illumination, when the illumination of other unit of light application ratio of certain unit is strong, because the relation that photogenerated current is directly proportional with intensity of illumination, this element will produce the photogenerated current of Duoing than other unit, at this moment, unnecessary photogenerated current will be stored in the electric capacity, reduce constantly output automatically in next illumination; When a little less than the illumination that certain other unit of unit light application ratio is subjected to, because the plate condenser energy storage is arranged, this moment, not enough electric current was provided by plate condenser, alleviated the influence of hot spot effect; Be generalized to the situation of photovoltaic arrays similarly, the illumination of certain assembly fluctuation since its inside be the band energy storage the photovoltaic cell unit and can be at first after self balance, again with other assembly basically identical ground output power, thereby promote the power generation performance of integral body.
