Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high V<sub>OC</sub> and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well...

We formed phosphorous(P)-ion-implanted n-BaSi<sub>2</sub> films on p-Si(111) substrates and demonstrated solar-cell functionality of the n-BaSi<sub>2</sub>/p-Si heterojunction under AM1.5 illumination. The BaSi<sub>2</sub> films were grown by molecular beam epitaxy, followed by implantation of P ions to the BaSi<sub>2</sub> films using PF<sub...

Hydrogenation of polycrystalline silicon (poly-Si) passivating contacts is crucial for maximizing their passivation performance. This work presents the application of Al2O3 prepared by atomic layer deposition as a hydrogenating capping layer. Several important questions related to this application of Al2O3 are addressed by comparing results...

In this work, we develop SiO<sub>x</sub>/poly-Si carrier-selective contacts grown by low-pressure chemical vapor deposition and boron or phosphorus doped by ion implantation. We investigate their passivation properties on symmetric structures while varying the thickness of poly-Si in a wide range (20-250 nm). Dose and energy of implantation...

This work shows an alternative surface cleaning method for c-Si wafers to replace the standard chemical procedures as RCA or HNO <sub>3</sub> which involve hazardous chemicals or unstable processes. The method consists in a high-temperature oxidation treatment (HTO) performed in a classical tube furnace that incorporates organic and metal...

In this work we develop a rear emitter silicon solar cell integrating carrier-selective passivating contacts (CSPCs) with different thermal budget in the same device. The solar cell consists of a B-doped poly-Si/SiO<sub>x</sub> hole collector and an i/n hydrogenated amorphous silicon (a-Si:H) stack acting as electron collector placed on the...

In this work, we present the application of poly-Si carrier-selective passivating contacts (CSPCs) as both polarities in interdigitated back-contacted (IBC) solar cell architectures. We compared two approaches to form a gap between the back-surface field (BSF) and emitter fingers. It is proved that the gaps prepared by both approaches are...
