In the first part of this paper, we review the developments which led to the present state-of-
the-art in the surface passivation of today's industrially predominant dopant-diffused …

Silicon wafer solar cells continue to be the leading photovoltaic technology, and in many
places are now providing a substantial portion of electricity generation. Further adoption of …

Solar photovoltaics researchers have devoted enough time to improve the performance of
various types of high efficiency crystalline silicon based solar cells including passivated …

We present arguments that additional effects besides laterally homogenous tunnelling might
occur in carrier-selective poly-Si/c-Si junctions:(i) the symmetrical electrical behaviour of n+ …

The evolution of the contact scheme has driven the technology revolution of crystalline
silicon (c‐Si) solar cells. The state‐of‐the‐art high‐efficiency c‐Si solar cells such as silicon …

The carrier transport through the silicon-oxide (SiO x) layer in tunnel oxide passivated
contact (TOPCon) c-Si solar cells has been studied experimentally and by simulation. The …

We present a detailed optimization of a hole selective rear contact for p–type crystalline
silicon solar cells which relies on full-area processes and provides full-area passivation. The …

We develop a plasma-assisted nitrous-oxide (N 2 O) gas oxidation (PANO) method to
prepare the ultrathin silicon oxide (SiO x) for polysilicon (poly-Si) passivated contact. The …

Carrier selective junctions using a poly-silicon/silicon oxide stack on crystalline silicon
feature low recombination currents J 0 whilst allowing for low contact resistivity ρ C. We …

In the pursuit of ever higher conversion efficiencies for silicon photovoltaic cells,
polycrystalline silicon (poly-Si) layers on thin silicon oxide films were shown to form …
