Energy Conversion Devices

The field of Energy Conversion Devices is facing a huge growth thanks to the increasing interest towards renewable energies, due to the need at the worldwide level to reduce carbon emission for energy production. Photovoltaics from utility scale plants is already at grid parity in many countries in the world, producing numerous opportunities for the industrial growth. PV is also is a major technology for energy harvesting, to power novel generation of silicon microsystems, systems on chip (SoC) and systems in package (SiP) devices.

The dominant PV technology is silicon based, but novel PV technologies may become very important in future, for example coupled to Si PV technology in utility scale plants, or for building integrated PV, or for powering nomadic or wearable electronics, etc. The large range of applications and opportunities is driving a strong effort in research. At IMM we are fully involved in this new trend of research on Photovoltaics. As an example, the recent H2020 project AMPERE, leaded by 3SUN / Enel Green Power, with the participation of CNR-IMM, (https://www.imm.cnr.it/projects/ampere-automated-photovoltaic-cell-and-module-industrial-production-regain-and-secure) is studying automated production lines for silicon bifacial solar cells with high efficiency. These promise high efficiency, low costs and high productivity in terms of kWh for installed kWp.

The research work at IMM is performed in many cases in strict collaboration with companies but with focus on novel approaches with strong potential for industrial application. The major areas of work at IMM are reported below. Further information on such topics can be reported by directly clicking at the links below.
