The growing demand of energy coupled with an increasing attention to the environmental impact have forced, in the last decades, toward the study and the development of new strategies in order to reduce primary energy consumptions.

The cogeneration (CHP) and the on-site generation (also known as distributed generation) could be the key strategy to achieve this goal; CHP systems allow to reduce the fuel consumption and pollutant emissions (in particular the greenhouse gases) compared to separate generation; moreover on-site-generation contributes to the reduction of the energy which is lost in electricity transmission, and increases the security in the energy supply.

In this scenario the Thermo-Photo-Voltaic generation (TPV) is obtaining an increasing attention; TPV is a system to convert into electrical energy the radiation emitted from an artificial heat source (i.e. the combustion of fuel) by the use of photovoltaic cells. A domestic gas furnace based on this technology can provide the entire thermal need of an apartment and can also contributes to satisfy the electrical demand.

In this paper, the main research activities on thermophotovoltaic generation developed in the last years at Institute of Materials for Electronics and Magnetism (IMEM) of Italian National Research Council (CNR), of will be presented and discussed.
