Carbon-based electrodes for perovskite solar cells

All-Carbon Electrodes for Flexible Solar Cells

Transparent electrodes based on carbon nanomaterials have recently emerged as new alternatives to indium tin oxide (ITO) or noble metal in organic photovoltaics (OPVs) due to their attractive advantages, such as long-term stability, environmental friendliness, high conductivity, and low cost. However, it is still a challenge to apply all-carbon electrodes in OPVs. Here, we report our efforts to...

Fully solution-processed transparent electrodes based on silver nanowire composites for perovskite solar cells.

We report all-solution-processed transparent conductive electrodes based on Ag nanowire (AgNW)-embedded metal oxide composite films for application in organometal halide perovskite solar cells. To address the thermal instability of Ag nanowires, we used combustive sol-gel derived thin films to construct ZnO/ITO/AgNW/ITO composite structures. The resulting composite configuration effectively pre...

Interpenetrating multiwall carbon nanotube electrodes for organic solar cells

Low concentrations of multiwall carbon nanotubes MWCNTs 1 wt % uniformly distributed within the donor layer of a heterojunction organic solar cell are shown to be an effective means of greatly reducing cell series resistance without compromising cell shunt resistance, resulting in an increase in cell fill factor of 50–60%. By chemically functionalizing MWCNTs with polar surface moieties, it is ...

Perovskite Solar Cells

Two-dimensional hybrid perovskites are used as absorbers in solar cells. Our first-generation devices containing (PEA)2(MA)2[Pb3I10] (1; PEA=C6H5(CH2)2NH3 , MA= CH3NH3 ) show an open-circuit voltage of 1.18 V and a power conversion efficiency of 4.73%. The layered structure allows for high-quality films to be deposited through spin coating and high-temperature annealing is not required for devi...
