Put.The principle of this scheme is：Incident sunshine is converted to electric energy after translucent perovskite solar cell part is absorbed,
And by absorb conversion 550~780nm range sections visible ray and infrared light, account for altogether incident solar energy 36~
40%, the energy can be first converted into after heat energy being converted to electric energy by thermo-electric device after collector lens focus, can significantly carry
The solar energy conversion efficiency of high whole system；In addition, solar power generation/frequency dividing/optically focused sub-device is due to frequency dividing optically focused work(
It can assemble solar energy, bring up to up to the solar energy current density on silicon solar cell, photoelectric transformation efficiency can be improved,
And reduce solar cell consumption.It can easily show that different band gap coordinate the thermoelectric material of different ZT values by Fig. 6
Hybrid system gross efficiency.If the perovskite solar cell battery for being 1.5eV with band gap, ZT values are 2 thermoelectric material, are combined
The gross efficiency of system is 40.5%.It is the Xiao Keli limit conversion efficiencies of the photovoltaic cell of different band gap as shown in Figure 8, Fig. 8 is
The limit conversion efficiency of thermoelectric generating device in the case of the different pyroelectric material performance figures of merit.By Fig. 7,8 as can be seen that thermoelectric power generation
The conversion efficiency of device is not as photovoltaic cell like that with the limiting efficiency with band-gap, as seen from Figure 9 with difference
The solar cell of band gap is combined, and the contribution rate of thermoelectric power generation can be between 6~18%, than battery stack improved efficiency space more
Greatly, it is compound by two kinds of different energy conversion regimes in addition, thermoelectricity has obvious complementary relationship with photoelectric energy on
Solar energy can be utilized by spectrum entirely, improve whole system efficiency, efficiency can reach more than 42%, be selected according to this figure most suitable
The cell band gap being combined with thermoelectric power generation unit, and draw optimal combined efficiency, the band gap of the solar cell material of matching
Scope is between 1.4~1.7eV.It is perovskite photovoltaic frequency dividing beam condensing unit preparation process flow chart shown in Figure 10.It was prepared
Cheng Wei:(1) frock/equipment and fixture are got out, the shaping of Fei Nier lens angles has prepared mainly by the grinding tool of different angles
Cheng Hou, is waited；(2) the transparent organic silicon glue of liquid is poured on mould；(3) vacuum mo(u)lding technique is used by perovskite solar-electricity
Pond is pressed on the mould for being marked with organic silica gel；(4) under conditions of middle low temperature, wait to be solidified, be stripped after solidification, form calcium titanium
Ore deposit spectrum divides beam condensing unit advantages:Organic silica gel is in cell backside, and part ultraviolet light is by glass filtration, and silica gel is indirect
Contact solar ultraviolet irradiation, the problem of reducing organic silica gel aging；Organic silica gel lens perovskite solar cell is whole
Body covering can also play battery secondary encapsulation protective effect.
Translucent perovskite solar cell, Fei Nier lens are followed successively by from top to bottom along sunshine incident direction, gathered
Light reflection mirror, thermoelectric generating device.Thermoelectric generating device can using 200~300nm solar spectral and 800~2500nm
Solar spectrum energy.Multistage high power concentrator is carried out through inverted conical " light funnel " condenser mirror and makes high energy current density luminous energy
It is uniformly distributed in receptor surface, recipient is thermoelectric generating device.
Device of solar generating of the invention based on translucent perovskite battery, not only significantly simplifies full spectrum solar energy
The structure of set composite generator unit, and solar energy is transmitted in photoelectricity compound power-generating unit, energy absorption with
The process of conversion is more reasonable, first, and sunshine, by sorption enhanced, can make full use of the scattered light in sunshine before optically focused,
The utilization rate of solar energy is improved, secondly, it is impossible to after the lower energy photon frequency dividing transmission changed, reduce perovskite thin film too
The thermic load of positive energy battery, reduces influence of the temperature to battery conversion efficiency, finally, employs Fei Nier lens and adds inversion to bore
Shape closed cavity limits the design of light, can reduce the reflection loss of infrared light.
