Resumen:

Energy level and power conversion efficiency were investigated in the inverted organic solar cells with configuration FTO/TiO2/P3HT:PC61BM/MoO3/Ag and FTO/PFN/P3HT:PC61BM/MoO3/Ag structures in a double electron transport layer (ETL) organic solar cell with configuration FTO/ TiO2/PFN/P3HT:PC61BM/MoO3/Ag. The influence of TiO2 and PFN as ETL was evaluated individually and together, in solar cells and an UV-Vis experiment, showing that the use of a double ETL can increase the efficiency up to 2.5 times compared to cells where only a single layer was used. The best cell built with double ETL showed a maximum efficiency of 4.29%.
