Description
Technical field
The present invention relates to solar cell and assembly field, relate in particular to crystal silicon battery assembly and crystal silicon battery system.
Background technology
Along with the whole world stays in day by day urgent without the population power consumption demand of electricity or power-shortage area more than 1,000,000,000, the electrical problem that solves the short of electricity crowd has become very urgent.And the natural calamity that causes along with earth intensification is day by day serious, and people's environmental protection consciousness grows to even greater heights.Therefore, solar energy has obtained various countries researchers' extensive concern as reproducible clean energy resource, and solar cell industry has obtained fast development.
In recent years, solar cell application has obtained surprising progress.And crystal silicon solar batteries is because to have photoelectric conversion efficiency high, and the advantages such as production technology maturation are all the time in occupation of the overwhelming majority of world's solar cell total output.Although the production technology of crystal silicon solar batteries is always in continuous progress, the photoelectric conversion efficiency of crystal silicon solar batteries can not allow people satisfied at present.
Except the research to the manufacture craft of solar battery sheet own and material, the making of solar module and interconnection technique also can have a huge impact solar cell system.Improve assembly CTM(Cell to Module, battery is to the assembly transfer ratio) value, can improve the power output with the efficient cell piece, in other words, can improve the utilance of battery; And then can further reduce the photovoltaic electric power cost, accelerate popularizing of photovoltaic electric power application.Therefore, the research for solar module also is present photovoltaic industry practitioner's study hotspot.
Existing solar cell system adopts large-sized battery to be formed by connecting usually, although this large-sized battery connection number of times is less, also than being easier to operation, the assembly electric current is larger, and battery power consumption is also large, underaction.If connect into solar cell system with compact battery, the then electrical component reduction that fails to be convened for lack of a quorum, thermal effect also can correspondingly reduce, and then improves battery efficiency; But compact battery is connected into large solar cell system, need repeatedly to connect, complicated operation easily causes power loss at interface.
Therefore need a kind of higher assembly electric current that both do not had, the solar module that can also simplify the operation can be installed again flexibly.
Summary of the invention
Contradiction between the power that runs into when solving composition solar cell system of the prior art and the assembling flexibility the invention provides and a kind ofly can effectively reduce the assembly electric current, can take into account again the crystal silicon battery assembly of assembling flexibility.
