This work presents a hybrid solar cell made with quantum dots and poly [(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9–dioctylfluorene)] (PFN), which is commonly used as electron transport layer in organic solar cells. Those cells were fabricated by Successsive Ionic Layer Adsorption and Reaction (SILAR) method and spin coating. The configuration used in this work was: TiO2/PbS/PFN/CdS/ZnS. The presence of PFN produced an increase of 33% in the short circuit current (JSC) respect to the sample of reference: TiO2/PbS/CdS/ZnS. Such increase in current caused an increment of the cell efficiency from 2.6% to 3.6%. PTB7 was also used has donor in our hybrid solar cells instead of quantum dots, when the PFN is added in this system, the current increased 60% respect to the cell of reference and the efficiency increased from 1.1% to 3.0%.
