Highly doped junctions of a Si solar cell function as membranes that block minority carriers
and, at the same time, provide a high conductivity for transporting majority carriers to the …

The year 2014 marks the point when silicon solar cells surpassed the 25% efficiency mark.
Since then, all devices exceeding this mark, both small and large area, with contacts on both …

The successful realization of carrier-selective contacts is a crucial prerequisite to
approaching the theoretical efficiency limit of silicon solar cells. The herein proposed carrier …

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 …

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 …

Solar cells rely on the efficient generation of electrons and holes and the subsequent
collection of these photoexcited charge carriers at spatially separated electrodes. High wafer …

Carrier-selective contacts (ie, minority carrier mirrors) are one of the last remaining obstacles
to approaching the theoretical efficiency limit of silicon solar cells. In the 1980s, it was …

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 …

Dopant‐free, carrier‐selective contacts (CSCs) on high efficiency silicon solar cells combine
ease of deposition with potential optical benefits. Electron‐selective titanium dioxide (TiO2) …

With a global market share of about 90%, crystalline silicon is by far the most important
photovoltaic technology today. This article reviews the dynamic field of crystalline silicon …
