The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has
currently aroused the interest of 2D material researchers. In this review, first, the …

Photovoltaic (PV) technology offers an economic and sustainable solution to the challenge
of increasing energy demand in times of global warming. The world PV market is currently …

To further increase the conversion efficiency of crystalline silicon (c-Si) solar cells, it is vital to
reduce the recombination losses associated with the contacts. Therefore, a contact structure …

Passivated contacts based on low-pressure chemical vapor deposited (LPCVD) heavily-
doped poly-Si and a thin SiO x layer are explored for the application in an interdigitated back …

Passivating contacts are indispensable for achieving high conversion efficiency in crystalline-
silicon solar cells. Their realization and integration into a convenient process flow have …

We investigate the junction resistivity of high-quality carrier-selective polysilicon on oxide
(POLO) junctions with the transfer length method. We demonstrate n+ POLO junctions with a …

Ion-implanted poly-crystalline silicon (poly-Si), in combination with a tunnel oxide layer, is
investigated as a carrier-selective passivating contact in c-Si solar cells based on an …

Despite the existence of several highly effective and well-characterized passivating
materials for crystalline silicon surfaces, the topic of surface passivation and the …

We determined the density of defect states of poly-Si/SiO x/c-Si junctions featuring a wet
chemical interfacial oxide from lifetime measurements using the MarcoPOLO model to …

In this study, we focused on understanding the roles of a polysilicon (poly-Si) layer in poly-
Si/SiOx/c-Si passivating contacts. Passivating contact formation conditions were varied by …
