| Summary: | 碩士 === 國立成功大學 === 光電科學與工程學系 === 102 === In this work， we present a fabrication of all-solid-state， methylammonium lead iodide (CH3NH3PbI3)/ [6，6]-phenyl-C61-butyric acid methyl ester (PC61BM)， donor/acceptor bilayer-heterojunction (BHJ) hybrid solar cells. Spinning N， N-dimethylformamide (DMF) solution of equi-molarmethyl ammonium iodide and lead iodide on the substrate forms a thin CH3NH3PbI3 perovskite film. And then， we use thermal to deposit a thin PCBM (acceptor)、BCP(exciton blocking layer) and Al(electrode). The CH3NH3PbI3 perovskite could sereve two functions as light harvester and hole conductors. Besides， perovskite harvests a wide range of light from visible to near-infrared. By varying the annealing temperature of NiOx， we can modulate the work function of hole transport material and find out a better match of perovskite’s HOMO. The best of our devices deliver Voc=0.9V、Jsc=13.13 mA/cm2、FF=65.55%、η=7.75 %、Rs=4.98 Ω*cm2 and Rp=7.2 MΩ.This result proves the formation and function of a hybrid BHJ in the NiOx/ CH3NH3PbI3 perovskite/PC61BM interface to yield the photovoltaic effect under the solar irradiation. We believe this progress may be a good concept for all-inorganic perovskite-based thin-film solar cells and tandem photovoltaics.
