Abstract
The invention relates to a high performance modular solar energy photovoltaic cell assembly, characterized in that: detecting all solar energy silicon chips in output characteristic, connecting in series with a single solar energy silicon chip of the current and connecting in parallel with a single solar energy silicon chip of the voltage. The solar energy silicon chip clusters output in same voltage are connected in parallel to form a small unit. The small units with same current output characteristic are connected in series to form a middle unit. The middle units with same voltage output characteristic are connected in parallel to form an output unit. The advantages of the invention are that the output efficiency of a power output unit formed by the solar energy silicon chips with near performance is maximal.
Description
Technical field
The present invention relates to a kind of high performance modularization solar photocell assembly.
Background technology
At present along with oil, the exhaustion of coal resources, and people are to the growing interest of carbon emission, green solar energy is subjected to favoring widely, because solar power generation can solve many problems, therefore each state is all greatly developing solar photocell now, because the electric power that the solar silicon wafers in the unit are can send is smaller, and be limited to the restriction of manufacturing technology, general solar silicon wafers 100 redress centimetre about, the electric power that it can send is generally at 3V, electric current is at tens MA, therefore when practicability, will be with the requirement of solar silicon wafers according to power output, carry out series-parallel connection and form a frame unit then, basically form an electric power output unit of one 2 square metres, usually under normal solar radiation, can export tens V, the electric power of several thousand MA, because the technology content of the processing process of solar silicon wafers is higher, production cost is bigger, therefore present every watt price is about 200 yuan, therefore under existing technical conditions, should increase the power output of each electric power output unit as much as possible, but at present when the solar silicon wafers connection in series-parallel of carrying out an electric power output unit, the output characteristic of solar silicon wafers is not screened, and owing to the solar silicon wafers external performance index separately of each sheet of producing is not quite similar, if therefore that current characteristics is different solar silicon wafers strings together, then cause whole a string solar silicon wafers electric current to be output as minimum, and in case when the solar silicon wafers of the different voltages of some strings output is connected in parallel, its voltage is output as in the string minimum, therefore existing screening the and the outside of solar power silicon chip arrays after processing be output as the poorest.
Summary of the invention
The objective of the invention is to solve in the prior art and in producing solar battery cell, cause the outside of the solar battery cell of making to be output as the poorest problem, a kind of method of making the high-performance solar photocell assembly is provided because of solar silicon wafers not being screened.The present invention designs a kind of method of making the high-performance solar photocell assembly, it is characterized in that: all solar silicon wafers are carried out the detection of output characteristic, with the single solar silicon wafers series connection bunchiness of electric current, in a row in parallel with the single solar silicon wafers of voltage.The solar silicon wafers string one-tenth junior unit parallel with one another of identical voltage output.The junior unit of same current output characteristic is connected into middle unit.The middle unit of identical voltage output characteristics also is unified into output unit.Advantage of the present invention is the power output maximum that enables an electric power output unit of the approaching solar silicon wafers composition of performance.
Description of drawings
Accompanying drawing is a solar silicon wafers catenation principle schematic diagram of the present invention,
Below in conjunction with drawings and Examples the present invention is elaborated,
Embodiment
1 is solar silicon wafers among the figure, all solar silicon wafers are carried out the detection of output characteristic with accurate instrument, detect electric current, the voltage output parameter of every solar silicon wafers, single solar silicon wafers series connection bunchiness with same current, then with the solar silicon wafers string one-tenth junior unit parallel with one another again of identical voltage output, the junior unit of same current output characteristic is connected into middle unit again, at last with the middle unit of identical voltage output characteristics and be unified into final output unit.Because through screening, therefore can get rid of the power output that the most bad collocation is formed, thereby can obtain optimum power output, the power output that can screen an electric power output unit of forming after testing in identical solar silicon wafers can be greater than 3% of the power output that obtains without sieve, and each electric power output unit can obtain to overflow 2 watts.One loses, and single output unit is may gap not obvious, but then the gap of power output is just very objective for large-scale solar array, may be exactly thousands of watts.
