The present invention impinges upon solar energy on the little silicon photocell plate by a concentrator with converging, has significantly reduced the area of electrooptical device, has made full use of the generating capacity of photovoltaic cell module, thereby has reduced the cost of system.
Figure 3 shows that the equivalent electric circuit of silicon photocell S, its battery equation is as follows:
Each symbol is defined as follows in the formula:
A-arbitrary curve fitting constant, it is worth between 1-5;
R
SThe series resistance of-battery;
R
SHThe parallel resistance of-battery;
The output current of I-battery;
I
L-photogenerated current;
I
O-diode saturation current;
The e-electron charge;
The terminal voltage of V-battery;
The K-Boltzmann constant;
T-absolute temperature.
According to the equivalent electric circuit of silicon photocell, parallel resistance R under a standard sun light intensity usually
SHValue very big, and series resistance R
SValue changes very little with light intensity.So V/R in the aforesaid equation
SHCan ignore for one.
But under the optically focused condition, parallel resistance R
SHValue can sharply descend owing to the surge of photoproduction minority carrier quantum count in the P-N knot, thereby the output current of battery is reduced.This deduction can be by following 5 experiment confirms:
Experiment one: the silicon photocell of common 125mm * 125mm is under a sunlight, and its output voltage is 0.55V, and output current is 4A, and power output is 2.2W.Under 10 times of optically focused conditions, its output voltage is 0.6V, and output current is 8.5A, and power output is 5.1W, and power output is brought up to 2.3 times.
Experiment two: the silicon photocell of common 125mm * 125mm is cut into the fritter battery of 31mm * 31mm, 4 series connection, under a sunlight, its output voltage is 2.2V, and output current is 0.29A, and power output is 0.64W.Under 10 times of optically focused conditions, its output voltage is 2.4V, and output current is 2.25A, and power output is 5.4W, and power output is brought up to 8.4 times.
Experiment three: with 4 parallel connections of above fritter battery, under a sunlight, its output voltage is 0.55V, and output current is 1.14A, and power output is 0.63W.Under 10 times of optically focused conditions, its output voltage is 0.61V, and output current is 2.7A, and power output is 1.65W, and power output is brought up to 2.7 times.
Experiment four: above fritter battery is cut into the fritter battery of 7.75mm * 31mm again, and with its series connection, under a sunlight, its output voltage is 2.2V, and output current is 0.07A, and power output is 0.15W.Under 10 times of optically focused conditions, its output voltage is 2.4V, and output current is 0.63A, and power output is 1.5W, and power output is brought up to 10 times.
Experiment five: will test four series-connected cell sheet, under 20 times of optically focused conditions, its output voltage is 2.4V, and output current is 0.95A, and power output is 2.3W, and power output is brought up to 15 times.
By above five experiments, confirm that the ordinary silicon photocell is under the high power concentrator condition, its parallel resistance can sharply reduce, and ordinary silicon photocell (size 103mm * 103mm, 125mm * 125mm, 152mm * 152mm) can regard the parallel connection of polylith small size battery as, so, can increase its parallel resistance, at this moment just can be used under the optically focused condition as long as large-sized battery is cut into small pieces, size is more little, and the light concentrating times of tolerance is big more.For the ordinary silicon photocell (as grating spacing 2mm, 3mm etc.) of different upper surface gate electrode density, experiment shows that the relative efficiency under high light intensity that upper surface gate electrode density is big is higher.
Further experiment shows, the ordinary silicon photocell that ordinary silicon photocell of making for polysilicon and monocrystalline silicon are made has above same experimental result.
And the wider range that allows for the resistivity of making photronic silicon materials, the scope that allows for the surperficial square resistance of P/N knot is broad also, and these parameters can be the same with the ordinary silicon photocell.
In addition, under same light concentrating times, the concentrator cell size is more little, and is favourable more to heat radiation, but unfavorable more for being packaged into the concentrator cell assembly.After weighing the advantages and disadvantages, get 10 times of optically focused conditions, ordinary silicon photocell (125mm * 125mm) be cut into 16 little side's sheets to be advisable with a slice, the corresponding concentrator of each little side's sheet, as long as the hot spot that converges of concentrator drops on little side's sheet battery,, power output there is not influence substantially if hot spot is more a little bit smaller than little side's sheet cell area, if hot spot than little side's sheet cell area more greatly, power output can corresponding reduction.In this case, power output is as testing as described in two, and efficient is approximately 8.4 times.If the solar tracking system precision is higher, also 1/16 small pieces can be cut into 2 again, become 1/32 small pieces, these 2 series connection, its efficient rises to 10 times, is a kind of comparatively ideal state.
The corresponding a slice concentrator of each baby battery sheet, this is not high to the uniformity requirement that converges hot spot, and is insensitive to converging the hot spot off-center yet.If corresponding concentrator of four small pieces battery series component that cuts into according to experiment three method, then the inhomogeneities of optically focused hot spot will have a strong impact on electric current output, if at this moment will test little side's sheet that four described small pieces make 15.5mm * 15.5mm into, corresponding concentrator of generous group that four little side's sheet batteries like this are composed in series, it is insensitive then concentrator to be converged the inhomogeneities of hot spot, but still to hot spot off-center position sensing.
