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 …

Hydrogenated amorphous silicon (a-Si: H) has been used for decades—doped and as
intrinsic absorber layers—in thin-film silicon solar cells. Whereas their effiency was improved …

To unlock the full performance potential of silicon heterojunction solar cells requires
reductions of parasitic absorption and shadowing losses. Yet the translation of the …

Here we report a certified efficiency of up to 25.11% for silicon heterojunction (SHJ) solar
cells on a full size n-type M2 monocrystalline-silicon (c-Si) wafer (total area, 244.5 cm 2). An …

Silicon heterojunction solar cells have high open-circuit voltages thanks to excellent
passivation of the wafer surfaces by thin intrinsic amorphous silicon (a-Si: H) layers …

Damage of the hydrogenated amorphous/crystalline silicon interface passivation during
transparent conductive oxide sputtering is reported. This occurs in the fabrication process of …

Doped hydrogenated amorphous silicon (a-Si: H) films of only a few nanometer thin find
application in a-Si: H/crystalline silicon heterojunction solar cells. Although such films may …

Excellent surface passivation induced by (i) a‐Si: H is critical to achieve high‐efficiency
silicon heterojunction (SHJ) solar cells. This is key for conventional single‐junction cell …

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

Silicon heterojunction (SHJ) solar cells employ nanometer-thin stacks of intrinsic and doped
hydrogenated amorphous silicon (a-Si: H) films as carrier-selective contacts. To achieve …
