Achieved a yield of 20.8% for solar cells tandem with the new material, aligning our country to international research
by Davide Madeddu
Research and technological innovation for high efficiency perovskite solar cells only. The challenge for the new frontier of photovoltaics starts from the Innovative Devices Laboratory of the Enea Research Center in Portici, where what the researchers call an “efficiency record” of 20.8 percent for perovskite solar cells has been achieved .
Where, by efficiency or yield of a photovoltaic cell we mean “the ratio between the electrical power available at the terminals of the photovoltaic cell and the power of the solar radiation that hits the surface of the cell itself”.

After the experiments on tandem cells, we look at the material that has revolutionized photovoltaic research in recent years, by virtue of its optoelectronic properties – the interaction between electronic devices and light – and the potential in the development of high-efficiency and cost-effective technologies. contents.
“The threshold reached is of particular importance – comments Paola Delli Veneri, head of the Innovative Devices Laboratory – and allows us to” align “our country with other international research groups”.
An important result achieved in the context of the “High efficiency photovoltaic project”, financed by the Program Agreement on Research of the electricity system between Enea and the Ministry of Economic Development.
