Tandem solar cells are the next step in the photovoltaic (PV) evolution due to their higher
power conversion efficiency (PCE) potential than currently dominating, but inherently limited …

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 …

Silicon heterojunction solar cells consist of thin amorphous silicon layers deposited on
crystalline silicon wafers. This design enables energy conversion efficiencies above 20% at …

The reduction in electronic recombination losses by the passivation of silicon surfaces is a
critical enabler for high-efficiency solar cells. In 2006, aluminum oxide (Al 2 O 3) nanolayers …

The high work function metal oxides, tungsten oxide (WO x) and molybdenum oxide (MoO
x), were investigated regarding their ability to form a hole-selective contact for a crystalline …

The electricity market from renewable energies is strongly driven by the pursuit of high
energy conversion efficiency, which at present represents the most effective pathway to …

The impact of post-deposition hydrogen plasma treatment (HPT) on passivation in
amorphous/crystalline silicon (a-Si: H/c-Si) interfaces is investigated. Combining low …

Amorphous/crystalline silicon heterojunction (SHJ) solar cells are well known for their
inherent high open-circuit voltage (V OC) potential, much better temperature coefficient …

In this paper we address the fundamental challenge of forming an efficient contact between
the p-type a-Si: H layer and n-type TCO's as contact layers in amorphous/crystalline silicon …

In this work, the intrinsic hydrogenated amorphous silicon (a-Si: H) layer of silicon
heterojunction (SHJ) solar cells was modified to improve carrier transport while maintaining …
