Descripción del proyecto
Nuevos conocimientos sobre celdas fotovoltaicas de triple unión de perovskita y silicio
La tecnología de celdas fotovoltaicas requiere más innovación para mejorar la generación de energía y la conectividad a la red. La tecnología de celdas de perovskita ha demostrado su potencial para aumentar la eficiencia y la fiabilidad durante la investigación y el desarrollo. El equipo del proyecto TRIUMPH, financiado con fondos europeos, tiene como objetivo avanzar en la investigación de las celdas de perovskita mediante el desarrollo de un innovador dispositivo de triple unión de dos terminales que combina perovskita y silicio para aumentar la eficiencia hasta un 33 %. Asimismo, en el proyecto se pretende mejorar los índices de reciclaje y la rentabilidad de los métodos de producción, además de reducir la dependencia de materias primas esenciales.
Objetivo
The TRIUMPH project aims to initiate the development of a future PV cell technology node, based on an advanced triple junction cell concept, that is widely considered to be the next technology node to come after tandems. Presently, there is considerable amount of attention and research and development (R&D) activities devoted to Pk/Si tandems and already promising cell efficiencies, reliability and outdoor performance results have been obtained. The highest efficiency reported for a 2-terminal (2T) Pk/Si tandem is 29.8%, which has already gone past the Auger limit of Si. Therefore, in TRIUMPH, we plan to venture a step further than tandems by targeting TRIple junction devices, that can add the extra “OOMPH” (hence the name TRIUMPH) needed to reach efficiencies even >33%. These 2T triple junction devices will be based on perovskites for the middle and top cells and silicon for the bottom cell and will build on the knowledge garnered in the field of Pk/Si tandems. Additionally, cost-effective processing techniques that are industrially viable will be selected for scale-up developments, with minimal upscaling performance loss and degradation during reliability testing and outdoor monitoring. As we enter the tera-watt (TW) era of PV deployment, using earth-abundant materials and enforcing circularity become necessities. Towards this objective, we not only explore options that reduce critical raw materials (CRM) such as silver (Ag) and indium (In) in the triple junction devices, but also apply design for recycling principles to the triple junction modules. The consortium consists of 14 complementary partners from both research institutions and industry, each bringing their best forte to the table, which will help to establish the pathway and the value chain for future multi-junction modules. In this way, TRIUMPH would help the European Union (EU) to maintain its technological leadership in the PV domain for the future generation of PV technologies.
