Compositional analysis of (p) a-SiCx:H emitter layers for enhanced short-circuit current density in SHJ solar cells Salimi, Arghavan; Sedani, Salar H.; Ghasemi, Milad; Ünver, Seda Kılıçkaya; Dönerçark, Ergi; Koç, Mehmet; Yıldız, İlker; Depauw, Valerie; Radhakrishnan, Hariharsudan Sivaramakrishnan; Nasser, Hisham; Turan, Raşit (2026-11-01) One of the loss mechanisms in silicon heterojunction (SHJ) solar cells is the parasitic absorption in the p-type emitter layer. In order to increase the device performance, parasitic absorption losses should be decreased b...
Chloride-Substituted Perovskite Enables Thick Middle Cell for Perovskite/Perovskite/Silicon Triple-Junction Solar Cells Heydarian, Minasadat; Fischer, Oliver; Heydarian, Maryamsadat; Wo, Yujie; Karalis, Orestis; Bett, Alexander J.; Sedani, Salar H.; Yıldız, İlker; Artuk, Kerem; Milot, Rebecca L.; Schindler, Florian; Wolff, Christian M.; Schubert, Martin C.; Borchert, Juliane; Schulze, Patricia S. C.; Glunz, Stefan W. (2026-06-28) Increasing the thickness of perovskite thin film absorbers allows for enhanced photo absorption, which increases the current and performance of the solar cells. In multijunction devices, thickness optimization is critical ...
