Abstract
This invention relates to solar energy battery especially to solar energy battery set by complexing crystal silicon solar energy battery single-board and noncrystalling silicon solar battery single-board, the crystal silicon solar energy battery charges the battery for a few hours about fine day non and noncrystalline silicon solar battery charges the battery for the rest time and cloudy rainy days to make the battery at floating state often, so as to prolong the life time of the battery.
Description
Technical field
The present invention relates to solar cell, particularly with crystal silicon solar energy battery and the compound composition solar battery group of non-crystal silicon solar cell.
Background technology
Crystalline silicon (containing monocrystalline silicon and polysilicon) solar cell in the time is converted to solar energy the ability of electric energy about former and later two hours at high noon of fine day higher, thereby be used widely.It is then lower to reach cloudy power supply capacity at this moment beyond the section.
Non-crystal silicon solar cell about former and later two hours at high noon of fine day in time photoelectric conversion efficiency be low far beyond crystal silicon solar energy battery, but long period and cloudy day beyond fine former and later two hours at high noon, comparing with crystal silicon solar energy battery has higher power supply capacity.And the non-crystal silicon solar cell of equal-wattage than crystal silicon solar energy battery price low nearly half.
Crystalline silicon (containing monocrystalline silicon and polysilicon) solar cell spectral response characteristic curve such as Fig. 1, its peak in the spectral response is near 860nm, in near infrared spectral range and higher near the ability that in the infrared limit of visible spectrum is electric energy with transform light energy, conversion efficiency is about 13-15%, is fit to use about fine former and later two hours at high noon.Non-crystal silicon solar cell spectral response characteristic curve such as Fig. 2, its peak in the spectral response is near 530nm, transfer capability is lower near infrared, thereby fine former and later two hours at high noon opto-electronic conversion ability is starkly lower than crystal silicon solar energy battery, be about 50% of crystal silicon solar energy battery with area non-crystal silicon solar cell conversion efficiency, quite a while beyond fine former and later two hours at high noon and cloudy day (this moment, infrared light was weak), its opto-electronic conversion ability is then far beyond the crystal silicon solar energy battery height.The characteristic of above-mentioned two class solar cells has been limited to the application degree of depth and range separately.
In addition, the charge-discharge characteristic of the employed charging accumulator of solar cell is: the life-span is generally and discharges and recharges for 500 times (a year and a half approximately), if can make storage battery always be in floating charge state, then the life-span can prolong greatly, when storage battery is in floating charge state fully, the life of storage battery is about 10 years, as long-time only discharge, do not charge, make accumulator electric-quantity emptying, then storage battery will significantly reduce the life of storage battery because of recovering charging ability again.
Summary of the invention
The objective of the invention is to have above-mentioned problem and shortage, a kind of composite solar battery group is provided, utilize two class solar cells characteristic separately, mate with compound in order to overcome two class solar cells.Solar battery group after compound, overall efficiency are much higher than crystalline silicon or amorphous silicon monomer solar cell, and can both effectively power under multiple weather conditions.Fine former and later two hours at high noon, all the other times were based on the non-crystal silicon solar cell generating based on the crystal silicon solar energy battery generating.Make it reach best configuration, system cost then reduces more than 25% with crystal silicon solar energy battery more separately.
Technical solution of the present invention is:
A kind of composite solar battery group, it is characterized in that at least one crystal silicon solar energy battery veneer 1 with after anti-reverse charge road connects, at least one non-crystal silicon solar cell veneer 2 with after anti-reverse charge road connects, is combined with each other two battery veneer parallel connections and forms a composite battery group.
With the crystal silicon solar energy battery veneer and the non-crystal silicon solar cell veneer of various area ratios, be encapsulated on the same solar panel side by side or encapsulate separately and form a composite battery group more side by side.
Also the PN junction of non-crystal silicon solar cell veneer can be shaped at plated film on glass, rete is transparent, and the compacting that again non-crystal silicon solar cell veneer and the good crystal silicon solar cell sheet array of a welding superposeed up and down is packaged into a composite solar battery group.
Composite solar battery assembly spectral response characteristic curve such as Fig. 3 are combined with each other both effectively, performance effect separately.Press the crystal silicon solar energy battery power generation characteristics, charged a battery several hours normal fine high noon daytime every day, the discharge in night, and the life-span is generally 500 times and discharges and recharges; And overcast and rainy for a long time, crystal silicon solar energy battery can't charge, accumulator electric-quantity emptying, and the life of storage battery significantly reduces.The crystal silicon solar energy battery group is having continuous overcast and rainy area to tend to that this thing happens.And the present invention with overcast and rainy can both make storage battery often is in floating charge state in the some time with non-crystal silicon solar cell and crystal silicon solar energy battery combination before and after high noon, and the life of storage battery is prolonged several times.Greatly reduce system cost, improved efficient, increased adaptability.Thereby make the solar photoelectric product more the district be applied.
