Photovoltaic power generation is pivotal in the transition to a clean energy system and the achievement of the zero-emissions target. To that end, it is important to enhance affordability, security of supply and sustainability of PV technologies along with further efficiency improvements. Tandem-junction cell architectures present a path towards higher module efficiencies over single-junction designs, because of the ability to absorb more efficiently the different wavelength regions of the solar spectrum by means of separate devices (monolithically integrated and bonded/mechanically stacked). This enables surpassing the limiting efficiency of single-junction Si (~29%), which has neared its theoretical limit. As module costs drop, balance-of-systems costs dominate the cost of PV installations, and gains in efficiency could influence more the overall system costs, the energy yield/m2 and hence the land use or the integration potential of the technology. The aim is to develop tandem cells and modules that will reach efficiencies >30%, offer the same lifetime and degradation rate as standard crystalline panels at an only marginally higher cost, creating thus a viable economic pathway for commercialisation of these technologies. The proposal should address all of the following: Develop novel concepts based on earth-abundant materials that optimise PV cell and module architecture, increase durability, decrease losses and target very high efficiencies, taking also into consideration specific applications; Employ simple, scalable and low-cost processing techniques; deliver proof-of-concept for equipment development to support novel layer deposition; as well as Ensure compliance with the relevant standards at laboratory scale, also considering the specific applications targeted among other actions as outlined. The award value is EUR 25 000 000.
