The better photoelectric performance of thin-film TiO2/c-Si heterojunction solar cells based on surface plasmon resonance

Results in Physics, 2021
In this work, the absorption of solar energy of thin-film c-silicon (silicon is 1 μm) heterojunction solar cells (SSCs) with the combination of Ag nanoparticles (NPs) and TiO2 inverted triangular prism (IP) is enhanced significantly.

Functional Dithienopyrazines – Structure-Property Relationships

European Journal of Organic Chemistry, 2023
Dithienopyrazines are only scarcly used as building blocks in organic electronic materials. Here, we report efficient preparation and investigation of syn- and anti-dithienopyrazines, which were functionalized with triaraylamine units to provide different series of donor-acceptor-donor-type materials.
