PEROVSKITE SOLAR CELLS - CHOSE AMONG KEY MARKET PLAYERS

According to the new report of the European Commission, CHOSE is one of the Key Market Players in the perovskite photovoltaic technology.

In this Report CHOSE, coordinated by prof. Aldo Di Carlo, figures as one of the leading centers both in the realisation of perovskite solar cells and in the development of photovoltaic modules based on this technology.

Together with CHOSE, only the Swiss Center for Electronics and Microtechnology (CSEM) has been indicated in the Report as a "key market player" in the perovskite photovoltaic sector.

An important result to which, in joint action, other research groups of the University of Rome "Tor Vergata" have contributed, including the one led by prof. Silvia Licoccia (Department of Chemical Sciences and Technologies).

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.

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.
