Description
Technical field
The present invention relates to technical field of solar batteries, and in particular to a kind of solar cell synergistic film.
Background technology
Perovskite solar cell and organic solar batteries are that the class risen in recent years has the promising sun very much
Energy battery, they all have the outstanding advantages such as photoelectric transformation efficiency is high, cost is low, making is simple.Therefore, it is this kind of in recent years too
The research of positive energy battery associated materials and device technology turns into the forward position studied both at home and abroad and focus.The perovskite sun is improved at present
The technological means of the photoelectric transformation efficiency of energy battery is main by following two aspects：First, the material composition of perovskite battery is adjusted, is ground
The more excellent material of volatility substitutes original hole transmission layer, calcium titanium ore bed or electron transfer layer, or to original thing
Matter composition carries out structural behaviour adjusting and optimizing；2nd, the pattern of optimization structure or regulation and control each layer of perovskite battery is interface characteristics to optimize
Energy.These measures cause the photoelectric transformation efficiency of perovskite solar cell to bring up to 20.1% rapidly from 3.8% in 5 years；
And organic solar batteries then have synthesis cost is low, function is easy to modulation, pliability and good film-forming property all features, and it is made
Making technique can be using film techniques such as spin coating or inkjet printings, it is easy to accomplish large area is manufactured, the light of organic solar batteries
Photoelectric transformation efficiency has been also up to 9%-10%.
Although perovskite solar cell has reached more than 20% photoelectric transformation efficiency, the light of organic solar batteries
Photoelectric transformation efficiency has been also up to 9%-10%, still, because the light-sensitive material that single battery is used is single, its theoretical effect
Rate is determined by its band gap, therefore can have theoretical limit, and the theoretical limit of the photoelectric transformation efficiency of such as crystal silicon solar batteries is about
For 30%.Because the Energy distribution in sunshine spectrum is wider, existing any material can only all absorb energy in sunshine
Amount can be worth high photon than its gap.Less photon will pass through battery in sunshine, and larger photon can not obtain profit
With.These energy losses limit heightening for the efficiency of solar cell.Therefore, by the solar cell of different band gap widths,
The many knot laminated cells of composition that gather into folds of being gone here and there from top to bottom according to band gap width are to increase substantially solar cell photoelectric conversion effect
The most direct means of rate.
The optical band gap of perovskite material is 1.55eV, and photoresponse scope is 300nm-800nm or so, organic solar electricity
The optical band gap in pond is by the structures shape of the polymeric material based on its photolytic activity coating, the light of existing organic solar batteries
Learn band gap also narrow, and the band gap of silicon is 1.12ev, and good complementation can be formed with perovskite energy gap, can also be with
The optical band gap organic solar batteries different from silicon form good complementation；Existing perovskite or organic polymer and silicon
Laminated cell is (such as Application No. 201510270147.7《Lamination solar cell based on perovskite battery and HIT batteries and
Preparation method》, Application No. 201310684058.8《A kind of complementary silicon thin film/organic lamination film sun of absorption spectrum
Can battery》) it is that perovskite battery or organic polymer battery are connected with silion cell, due to perovskite battery or organic
The electric current that polymer battery is produced is flowed directly into silion cell, and the stability of silion cell can be impacted；Perovskite battery or
Connected between organic polymer battery and silion cell by conductive layer, with the growth of use time, the element of conductive layer can occur
Infiltration, has influence on the normal operation of perovskite battery or organic polymer battery and silion cell；Perovskite or organic polymer with
The laminated cell of silicon is with the growth of use time, and the reason such as oxidation of its electrode also results in the phototranstormation efficiency of laminated cell
It is gradually reduced；And the service life of perovskite battery or organic polymer battery and silion cell is simultaneously differed, because
Each layer that this above-mentioned setting significantly limit in the laminated cell all reaches most long service life.Due to existing solar energy
The overwhelming majority in battery is silicon solar cell, therefore design one kind based on existing silicon solar cell and can improve light
The solar energy enhancing device of photoelectric transformation efficiency can not only avoid changing existing solar product, save huge be produced into
This, and quickly can promote and popularize, and have great society and economic implications.
