Surface passivation and optical design of silicon heterojunction solar cells

It has been predicted that due to the population growth the energy demand is increasing faster and faster. It has been well recognized that depleting fossil-fuel resources will not fulfill the energy need of the future world. Not to mention the problem of global warming caused by its combustion, and of energy security as a result of geopolitical...

Effective Passivation of Black Silicon Surfaces via Plasma-Enhanced Chemical Vapor Deposition Grown Conformal Hydrogenated Amorphous Silicon Layer

Solar cells based on black silicon (b-Si) are proven to be promising in photovoltaics (PVs) by exceeding 22% efficiency. To reach high efficiencies with b-Si surfaces, the most crucial step is the effective surface passivation. Up to now, the highest effective minority carrier lifetimes are achieved with atomic layer-deposited Al₂O...

Poly-SiO_x Passivating Contacts with Plasma-Assisted N₂O Oxidation of Silicon (PANO-SiO_x)

Passivating contacts are crucial for realizing high-performance crystalline silicon solar cells. Herein, contact formation by plasma-enhanced chemical vapor deposition (PECVD) followed by an annealing step is focused on. Poly-SiO_x passivating contacts by combining plasma-assisted N₂O-based oxidation of silicon (PANO-SiO...
