The global photovoltaic (PV) market is dominated by crystalline silicon (c-Si) based
technologies with heavily doped, directly metallized contacts. Recombination of photo …

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 …

We demonstrate damage-free laser contact openings in silicon oxide layers on
polycrystalline silicon on oxide (POLO) passivating contacts. A pulsed UV-laser evaporates …

The efficiency of photovoltaic energy conversion is a decisive factor for low-cost electricity
from renewable energies. In recent years, the efficiency of crystalline silicon solar cells in …

This paper presents a comprehensive overview on printing technologies for metallization of
solar cells. Throughout the last 30 years, flatbed screen printing has established itself as the …

Despite the maturity of crystalline silicon photovoltaics (c-Si PV), the last 6 years have seen
a string of efficiency improvements, most of which are centered around reducing the losses …

High-efficiency silicon solar cells strongly rely on an effective reduction of charge carrier
recombination at their surfaces, ie surface passivation. Today's industrial silicon solar cells …

The article commences with a review focusing on three critical aspects of the perovskite/Si
tandem technology: the evolution of efficiencies to date, comparisons of Si subcell choices …

We present experimental results for interdigitated back contacted (IBC) solar cells with
passivating POLO contacts for both polarities with a nominal intrinsic poly‐Si region …

Doped polysilicon (poly-Si) passivating contacts have emerged as a key technology for the
next generation of silicon solar cells in mass production, owing to their excellent …
