Study Of Polymer Solar Cell Devices Performance

Polymer solar cells have manufacturing process simple, low cost, high security and curly, preparation of large area etc, and can have broad application prospects, more and more people's attention. This paper focuses on the development history of polymer solar cell development, the present situation and existing problems were discussed, introduces the related knowledge of polymer solar cells.In order to obtain high energy conversion efficiency, this paper studies the annealing temperature on the influence of polymer solar cell device, and annealing, and on the basis of the active layer in solar cells and the cathode joined a thin layer of ZnO between as hole linings. Through the experiment, we get: annealing temperatures affecting polymer solar cells directly with the energy conversion efficiency, P3HT: PCBM as polymer solar cell activity in the annealing temperature layers for 130℃works best when 2.65%, energy conversion efficiency reached; After adding ZnO layer device, the energy conversion efficiency was improved obviously, from originally of 2.65% non-smooth higher.We adopt a new electronic give body materials, and electronic receptors materials PCDTBT PC₇₁BM mixes of polymer solution as solar cells were active layer, four kinds of different structure of the solar cell device with traditional activity, through P3HT: PC₆₁BM material of comparison, found PCDTBT: spin coating PC₇₁BM active layer thickness of 80nm, batteries for the performance of the new materials, best can make battery energy conversion efficiency greatly improved, and its battery 100mw/cm² devices in the light intensity, open 0.89 V, voltage of short-circuit current density of cm², averaged 12.3 mA/energy conversion efficiency for 5.38%.This paper also studies the electrode modified layer of polymer solar energy conversion efficiency, we the influence of the same structure, preparation of polymer hole-transporting layers of organic solar battery device of the device, found the performance and hole-transporting layer on conductivity. Along with the increase of hole-transport layer conductivity, the device short-circuit current density increases, open the voltage and the fill factor decreased. As with PEDOT: PSS hole-transport layer, the performance of the device, the energy conversion efficiency achieve best 5.03%.
