IMPORTANCE OF FERROELECTRIC DOMAINS

importance of ferroelectric domains for the performance of perovskite solar cells

On the importance of ferroelectric domains for the performance of perovskite solar cells

The effect of ferroelectric polarization patterns in MAPbI3 on JV characteristics has been analyzed. We discuss models for the polarization orientation pattern and magnitude of the ferroelectric domains. Simulations performed on real patterns show that the presence of ordered ferroelectric domains, even with a weak characteristic polarization magnitude enhances the power conversion efficiencies and are mandatory to reproduce the experimental J-V characteristics.

A Crystal Engineering approach for perovskite solar cells and modules fabrication out of the glove box

we fabricated high efficiency perovskite solar cells (PSC) and perovskite solar modules (PSM) utilizing several Hole Transport Layers (HTLs). The results show that the Crystal Engineering approach remarkably improved the device performance reaching a power conversion efficiency of 17%, 16.8% and 7% for spiro-OMeTAD, P3HT and HTL free, respectively.

Photoelectrochemical and spectrophotometric studies on dye-sensitized solar cells (dscs) and stable modules (dscms) based on natural apocarotenoids pigments

We present a study on dye-sensitized solar cells (DSCs) and we fabricate dye-sensitized solar modules (DSCMs) based on natural apocarotenoids extracted from the achiote's seeds (annatto). Use of less polar solvent such as diethyl ether improves the bixin concentration in the annatto extract which, was employed as sensitizer in the devices.
