On the chances and challenges of combining electron-collecting nPOLO and hole-collecting Al-p+ contacts in highly efficient p-type c-Si solar cells

Robby Peibst et al.

Summary: ISFH is following a distinct cell development roadmap, which combines an n-type doped electron-collecting poly-Si on oxide junction with an Al-alloyed p(+) junction for hole collection. Recent progress and specific conceptual aspects of this technology are discussed, along with a simulation-based sensitivity analysis. The article also presents a concept to reduce the gap between measured pseudo fill factor values and theoretically achievable values.

Fundamental microscopic studies on the etching behavior of silver pastes on poly-Si/SiOx passivating contacts

Raphael Glatthaar et al.

Summary: Screen printing of Ag paste is crucial for implementing polycrystalline-silicon/silicon oxide (poly-Si/SiOx) passivating contacts in industrial solar cells. Ag crystallites are predominantly formed within the poly-Si layer and stop at the thermal SiOx, thermal interface, causing a cuboidal shape. A multilayer approach with interlayer SiOx is presented to avoid direct contact with the underlying SiOx, thermal/crystalline-Si interface.

Process-Structure-Properties Relationships of Passivating, Electron-Selective Contacts Formed by Atmospheric Pressure Chemical Vapor Deposition of Phosphorus-Doped Polysilicon

Jannatul Ferdous Mousumi et al.

Summary: In this study, the authors investigate the relationships between process, structure, and properties of in situ phosphorus-doped polycrystalline silicon films produced using atmospheric pressure chemical vapor deposition techniques. The aim is to develop poly-Si passivating, electron selective contacts for low-cost crystalline silicon solar cells. The study demonstrates the importance of optimized annealing processes and post-hydrogenation treatments in achieving high-quality passivating contacts.

Progress with passivation and screen-printed metallization of Boron-doped monoPoly™ layers

Pradeep Padhamnath et al.

Summary: This study analyzes the properties of boron-doped polysilicon layers to understand the limitations of p + poly-Si based passivated contacts. Findings reveal that the sheet resistance and passivation quality are influenced by boron solid solubility and high diffusion temperatures. Metal contact properties are strongly dependent on the surface morphology and thickness of the poly-Si layer.

Contact Formation of Silver Paste and Atmospheric Pressure Chemical Vapor Deposition (n) Poly-Silicon Passivating Contacts on Planar and Textured Surfaces

Raphael Glatthaar et al.

Summary: One of the main challenges in the industrialization of the passivating contact approach for Si solar cells is the metallization process using screen-printed paste while maintaining low saturation current density. This study investigates the metal contact formation for passivating contacts on planar and textured substrates by using a non-commercial Ag paste to metallize APCVD (n) poly-Si. The results show that the paste creates deep imprints on textured silicon wafers due to the formation of silver crystallites at the pyramid tips, while on planar wafers, the silver crystallite growth stops at the interface between poly-Si and the Si wafer. Similar contact resistivities are observed in both textured and planar Si samples.

Morphology, microstructure, and doping behaviour: A comparison between different deposition methods for poly-Si/SiOx passivating contacts

Thien N. Truong et al.

Summary: Investigations and comparisons were made on the crystallographic structures, optoelectronic properties, and nanoscale surface morphologies of ex situ phosphorus-doped polycrystalline silicon (poly-Si)/SiOx passivating contacts formed by different deposition methods. It was found that higher diffusion temperatures lead to more crystalline films with rougher surface morphologies. Deposition methods also showed differences in deposition rates, surface roughness, and crystallinity of the finished poly-Si films, with LPCVD method having the lowest deposition rate and roughest surfaces.

Design rules for high-efficiency both-sides-contacted silicon solar cells with balanced charge carrier transport and recombination losses

Armin Richter et al.

Summary: Front- and back-junction silicon photovoltaics dominate the market due to lower manufacturing complexity, but achieving efficiency improvements remains challenging. An optimized design by Richter et al. has led to a 26.0%-efficient cell. While interdigitated back-contact cells offer the highest efficiency, both-sides-contacted cells are preferred in industrial production for their simplicity.

TOPCon-Technology options for cost efficient industrial manufacturing

Bishal Kafle et al.

Summary: This paper discusses cost-driven strategies towards industrial manufacturing of TOPCon-based solar cells, evaluating various process routes and pointing out uneven distribution of capital and operational costs in the production process. The study finds that TOPCon concepts can remain economically competitive against bifacial PERC if a minimum absolute gain in cell efficiency is maintained.

Impact of firing temperature on fire-through metal contacts to P-doped (n+) and B-doped (p plus ) poly-Si

Pradeep Padhamnath et al.

Summary: Screen-printed contacts to doped polysilicon layers with high-temperature fire-through pastes play a crucial role in the industrial acceptance of passivating contact solar cells. The study focuses on the behavior of fire-through contacts formed with pastes on both phosphorus-doped and boron-doped poly-Si layers. The research involves quantitatively analyzing metal crystallites formed at the interface and their impact on recombination current density. The findings on n-type bifacial solar cells confirm observations on contact formation and metal recombination.
