Major Field of Science: | Engineering and Technology | Field Category: | Materials Engineering | Keywords: | Hole extractions;Hole transport layers;Photovoltaic performance;Solution combustion;Power conversion efficiencies | Issue Date: | Feb-2019 | Source: | APL Materials, 2019, vol. 7, no. 2 | Volume: | 7 | Issue: | 2 | Journal: | APL Materials | Abstract: | A solution combustion synthesized hole transport layer (HTL) of spinel nickel cobaltite (NiCo 2 O 4 ) incorporating 3% Cu-2% Li was fabricated using the doctor-blading technique for planar inverted perovskite solar cells (PVSCs). PVSCs incorporating 3% Cu-2% Li-doped NiCo 2 O 4 showed an increase in Jsc and Voc device performance parameters compared to unmodified NiCo 2 O 4 , leading to power conversion efficiency (PCE) of 16.5%. X-ray photoelectron spectroscopy measurements revealed the tendency of Cu cations to replace preferably the surface Ni atoms by changing the surface stoichiometry of NiCo 2 O 4 , inducing a cathodic polarization. Ultraviolet photoelectron spectroscopy measurements unveiled the increase in the ionization potential by 0.1 eV for a co-doped NiCo 2 O 4 film compared to unmodified NiCo 2 O 4 -based HTL. We attribute the enhanced PCE of the inverted PVSCs presented to the improved hole extraction properties of 3% Cu-2% Li NiCo 2 O 4 HTL. | ISSN: | 2166532X | DOI: | 10.1063/1.5079954 | Rights: | © Author(s) | Type: | Article | Affiliation : | Cyprus University of Technology University of Crete University of Patras |
