PEROVSKITE SOLAR CELLS

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

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.

CRYSTAL ENGINEERING APPROACH

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.

FULLY-SPRAYED FLEXIBLE

Fully-sprayed flexible polymer solar cells with a cellulose-graphene electrode

Light, flexible and low-cost organic solar cells made entirely by spray and with an innovative cellulose and graphene-based electrode! The work, in collaboration with the Smart Materials group of the ISTITUTO ITALIANO DI TECNOLOGIA has been published on the important magazine "Materials Today Energy".

UNDER INDOOR ILLUMINATION

Highly efficient perovskite solar cells for light harvesting under indoor illumination via solution processed sno2/mgo composite electron transport layers

A new architectures in CH3NH3PbI3 based planar perovskite solar cells incorporating solution processed SnO2/MgO composite electron transport layers that show the highest power outputs ever reported under typical 200–400 lx indoor illumination conditions.

SOLAR CELLS ON PAPER

Perovskite solar cells on paper and the role of substrates and electrodes on performance

The first perovskite solar cell (PSC) fabricated directly on a paper substrate with a maximum power conversion efficiency of 2.7% is here reported.

APOCAROTENOIDS PIGMENTS

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.

PEROVSKITE SOLAR MODULES

Fully laser processed Perovskite Solar Cell modules with 95% Aperture Ratio

Laser patterning has been applied to realize Perovskite solar modules with a ratio between active and total substrate area of 95% and an efficiency of 9.3%. These values are new records for large area (14.5 cm2) fully laser processed perovskite devices. This work signs a forward step to the industrialization of perovskite based solar technology. Results have been published on IEEE Journal of Photovoltaics DOI: 10.1109/JPHOTOV.2017.2732223

GRAPHENE-PEROVSKITE

Graphene-Perovskite Solar module with efficiency 12.6% on 50 cm²

Graphene interface engineering (GIE) is proposed as an effective way to boost efficiency in Perovskite solar cells and modules. A record efficiency of 12.6% on 50 cm2 module active area has been achieved by introduce Graphene in the mesoporous TiO2 and lithium neutralized graphene oxide (GO-Li) at the mTiO2/perovskite.
Results have been published on ACS Energy Lett. 2017, 2, 279−287

PEROVSKITE MODULE

We fabricated the first perovskite-based monolithic series-type module showing very promising results in terms of the power conversion efficiency, the reproducibility of the fabrication process and long-term stability.

We fabricated perovskite based solar cells using CH₃NH₃PbI_3-xCl_x with different hole transporting materials such as Spiro-OMeTAD and P3HT.

SDSC MODULE

We fabricated the first solid state dye solar cell (SDSC) module using poly(3-hexilthiophene) (P3HT) as Hole Transport Material for the dye regeneration process.

A COATING FOR ALL

Fully sprayed polymer solar cell modules open the way to bring Photovoltaics nominally everywhere, thanks to spray coating conformability to virtually any kind of substrate.
