Co-annealing of PECVD boron emitters and poly-Si passivating contacts for leaner TOPCon solar cell fabrication

Christophe Ballif, Franz-Josef Haug, Sofia Libraro, Julien Hurni, Ezgi Genç

This study investigates the feasibility of a single-step annealing process for tunnel oxide passivating contact (TOPCon) solar cell fabrication to replace the conventional two-step approach. We present a novel method using a single thermal treatment to sim ...

Optical Monitoring of Water Side Permeation in Thin Film Encapsulation

Yves Leterrier, Stéphanie Lacour, Massimo Mariello, Kangling Wu

The stability of long-term microfabricated implants is hindered by the presence of multiple water diffusion paths within artificially patterned thin-film encapsulations. Side permeation, defined as infiltration of molecules through the lateral surface of t ...

Investigating laser beam shadowing and powder particle dynamics in directed energy deposition through high-fidelity modelling and high-speed imaging

Christian Leinenbach

Laser beam shadowing in directed energy deposition process occurs when in-flight powder particles partially block the laser beam, preventing it from fully reaching the melt pool. This blockage alters the beam's profile, introducing spatio-temporal randomne ...

Extrusion-based 3D printing of stiff materials for advanced photonic applications

Pauline Camille Charlotte Pradal

Certain biological materials, such as chameleons and peacocks, display bright and vivid colors. These colors are created by the constructive interference of light that is reflected from colloidal crystals, generating the so-called structural colors. These ...
