Production of Upgraded Metallurgical Grade (UMG) silicon for a low-cost high-efficiency and reliable PV technology
José Manuel Míguez Novoa, Volker Hoffmann, Eduardo Fornies +12
UMG-Si has the potential to reduce the cost of PV technology and to improve its environmental profile. In this contribution, we summarize the extensive work made in the research an…
Hydrogenated Aluminum Doped Zinc Oxide as Highly Transparent and Passivating Indium-Free Recombination Junction for TOPCon-Based Bottom Cell
Gökhan Altıner, Jons Bolding, Yiğit Mert Kaplan +4
Tandem solar cells offer a promising alternative to exceed the efficiency limits of single-junction silicon photovoltaics, yet they require high-performance recombination junctions…
High carrier lifetimes in UMG multicrystalline wafers after P- diffusion compatible with high-efficiency cell structures
Nerea Dasilva-Villanueva, Bülent Arıkan, Hasan Hüseyin Canar +7
High-quality multicrystalline Upgraded Metallurgical Grade Silicon (UMG-Si) offers significant advantages over conventional polysilicon-based PV technology, associated to lower cos…
