Abstract


Compared with traditional solar cells , polymer solar cells has its unique advantages , such as : low cost , simple preparation , lightweight and convenient , these advantages it is expected to become the future of alternative energy . Many research groups have committed to the development of polymer solar cells . P3HT and PCBM battery active layer of donor material and acceptor material , a detailed study of the Al electrode deposition annealing method and improve the structure of polymer solar cells , and a preliminary study of the impact of different solvents on the active layer . The study found With the improvement of the deposition rate and the deposition thickness in the experimental range , the degree of crystallinity of the Al film is enhanced, the grain size becomes larger ; application in the battery, an appropriate increase in the deposition rate can improve the performance of the battery . Increase the thickness of the Al deposition Jsc can increase the battery , but the battery Voc and FF but a decreasing trend with increasing thickness of the recession ultimately the performance of the battery . Battery annealing , and found that after annealing than before annealing is more conducive to improve the performance of polymer solar cells . After annealing , the cell efficiency of 1.93% ( V oc = 0.60V , J sc = 5.89mA/cm2 , FF = 54.7 %) ; by Al between the electrode and the active layer of appropriate thickness PCBM, structure of the battery will be improved , and further improve the battery performance . When the the PCBM thickness of 3nm , the Jsc of the battery reaches 6.43mA/cm2, the conversion efficiency increased to 2.09% . However , when the the PCBM thickness of further increases , the battery performance begins to decline . Chlorobenzene and o-dichlorobenzene two solvents on the active layer , solvent selection have a greater impact on the thickness of the active layer morphology . O-dichlorobenzene as a solvent resulting active layer under the same conditions is thinner, and will produce a better phase separation . Using chlorobenzene as solvent , in the active layer of P3HT and PCBM can not be effectively separated . However, after annealing treatment , this state can be significantly improved.
