Description
[technical field]:
The present invention relates to the organic photoelectric field, relating in particular to a kind of is the organic photovoltaic battery and preparation method thereof of cathodic modification layer with the cesium acetate.
[background technology]:
Along with exhausting of global petroleum resources, the exploitation of new forms of energy seems and becomes more and more important.Solar cell is the device that luminous energy is converted into electric energy.As a feasible method that solves the world energy sources crisis, the utilization of solar energy becomes the frontier nature problem of a broad research.Therefore, greatly develop the solar cell industry, utilize solar power generation to become the new forms of energy strategy of countries in the world sustainable economic development.Scholarly forecast, to the year two thousand thirty photovoltaic generation will account for 50% of world generating total amount.The research and development of solar cell launch around following two key issues all the time: (1) improves photoelectric conversion efficiency and life-span (2) new material prepares to reduce cost.Up to the present, be the conversion efficiency that the photovoltaic cell of representative can reach 10-20% usually with the inorganic silicon material.Yet inorganic photovoltaic cell required high temperature, high vacuum in preparation process makes that the production cost of inorganic photovoltaic cell is very high, and this makes its application be very restricted.
1992, N.Sariciftci etc. found the ultrafast charge transfer phenomenon of the photoinduction between polymer/C60 first.Nineteen ninety-five A.J.Heeger etc. has proposed " body heterojunction " notion (BHJ), and " body heterojunction " type single polymer layer/C60 photovoltaic cell of invention has improved the contact area of D/A heterojunction greatly.And conjugated polymer/C60 body heterojunction solar cell is because simple in structure, easy preparation has caused people's extensive concern.Around the efficient that improves organic photovoltaic battery, the optimization people that leniently absorb, the design of narrow band gap polymer are synthesized to device architecture have carried out a large amount of exploratory developments.To have made energy conversion efficiency (PCE) be 3.3% polymer solar battery to C.J.Brabec in 2002 etc. by insert the LiF material between metal electrode and active layer, again energy conversion efficiency brought up to 3.85% in 2004.Professor A.J.Heeger of University of California at Santa Barbara in 2005 waits and has obtained 5% efficient by heat treatment P3HT:PCBM active layer.K.Lee in 2007 etc. have reported and have adopted transparent TiOx as the heterojunction that the cascade material forms laminated construction machine battery to be arranged that efficient is up to 6.5%.Adding oleic acid (oleic acid) and heat treatment in P3HT:PCBM after, Cao of South China Science ﹠ Engineering University a large bell academician seminar obtained 4.3% electricity conversion.On December 9th, 2008, Konarka company announces that the said firm has cooperated to obtain 6% conversion efficiency with A J Heeger seminar.On August 1st, 2010, Solarmer Energy announces that Li doctor Gang of the said firm leader's seminar has obtained the conversion efficiency of 8.13% organic polymer photovoltaic cell, and passes through the confirmation in American National regenerative resource laboratory (NREL).The efficient of the heterojunction battery that novel receptor the material ICBA and the P3HT of Beijing chemistry Li Yongfang of institute professor seminar of Chinese Academy of Sciences report formed reaches 6.5%.Organic photovoltaic battery with low, nontoxic, the easy preparation of its cost, be easy to the chemical constitution that realizes flexible device, can change organic material easily and effectively with control best can band, charge mobility, solubility even degree of orientation improve the characteristics such as efficient of battery and become hot research in recent years.If the photoelectric conversion efficiency of organic photovoltaic battery reaches 10%, just might realize commercially producing.
Device architecture is to influence the key factor that the photocell energy conversion efficiency improves.Solar cell performance can obtain in various degree improvement by electrode modification or other modifying interfaces.The purpose of electrode modification layer is that the highest occupied molecular orbital (HOMO) that makes its work function and donor material or the minimum not occupied orbital (LUMO) of acceptor material are complementary, to improve the electric charge ejection efficiency and to stop the transmission of exciton and non-collection charge carrier.Comparatively general cathodic modification material is a metal fluoride at present.Brabec etc. have studied influence (Brabec, the C.J. of lithium fluoride (LiF) cathodic modification layer to polymer solar battery; Shaheen, S.E.; Winder, C.; Sariciftci, N.S.; Denk, P.Appl.Phys.Lett.2002,80,1288).The insertion of LiF has increased fill factor, curve factor, short circuit current and the energy conversion efficiency of device, has reduced the series resistance of device.This is because LiF itself is the stronger ionic compound of a kind of polarity.It may be arranged in order on the interface and form a bed boundary dipole layer, thereby has reduced the work function of metal, makes to form good Ohmic contact between organic layer and the electrode.So just reduce the series resistance of device, increased the fill factor, curve factor and the short circuit current of solar cell.Other decorative material comprises TiOx (Hayakawa, A.; Yoshikawa, O.; Fujieda, T.; Uehara, K.; Yoshikawa, S.Appl.Phys.Lett.2007,90,163517), 2,9-dimethyl-4,7-diphenyl-1,10-phenanthrolene (BCP, bathocproine) (Vogel, M.; Doka, S.; Breyer, C.; Lux-Steiner, M.C.; Fostiropoulos, K.Appl.Phys.Lett.2006,89,163501).These inorganic matters (LiF, TiO
x) film forming need use expensive electron beam and vacuum deposition apparatus, method is comparatively complicated, and thickness is difficult for accurately control.Organic material BCP need be by the method film forming of vacuum evaporation, and thickness is relevant with experiment condition, costs an arm and a leg, can't large-area preparation.Angle from practicability is unfavorable for industrialized mass production.Li Yongfang etc. have studied influence (Tan, the Z. of solwution method TIPD cathodic modification layer to MEH-PPV photovoltaic cell device performance; Yang, C.; Zhou, E.; Wang, X.; Li.Y.Appl.Phys.Lett.2007,91,023509).At AM1.5G (100mW/cm
2) under the illumination, Jsc, Voc, FF, PCE are respectively by original 4.29mA/cm
2, 0.84V, 0.46,1.66% increases to 5.73mA/cm
2, 0.87V, 0.51,2.52%.Lee etc. are complementary the spatial distribution of light and the position of active layer as optical confinement layer with the TiOx of solution methods preparation, increase the absorption of light, help to improve the photoelectric current of device.Under AM1.5 illumination, Jsc, Voc, FF, η p are respectively by original 7.5mA/cm
2, 0.51V, 0.54,2.3% increases to 11.1mA/cm
2, 0.61V, 0.66,5% (Kim, J.Y.; Kim, S.H.; Lee, H.H.; Lee, K.; Ma, W.; Gong, X.; Heeger, A.J.Adv.Mater.2006,18,572).Therefore, seek cheap cathodic modification layer material or the machinable cathodic modification layer material of solution and just become problem demanding prompt solution in the organic photovoltaic battery preparation.
