Enhancing the Thermal Stability of Solution-Processed Small-Molecule Semiconductor Thin Films Using a Flexible Linker Approach

Kevin Sivula, Xavier Adrian Jeanbourquin, Xiaoyun Yu, Andrea Gasperini

Using flexible aliphatic chains to link conjugated molecular semiconductors affords a polymeric material that possesses defined conjugated segments but extended covalent connectivity, which enhances crystallinity and thermal stability in field-effect trans ...

Wiley-Blackwell2015

Two-dimensional (2D) semiconductors, consisting of single-sheets of layered transition metal dichalcogenides (TMD), are attracting enormous interest from both fundamental science and technology. Monolayer molybdenum disulfide (MoS2), a typical example from ...

Lanthanides in Solar Energy Conversion

Jean-Claude Bünzli, Anne-Sophie Chauvin

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...

Elsevier Science B.V.2014

, ,

Carrier recombination at the metal-semiconductor contacts has become a significant obstacle to the further advancement of high-efficiency diffused-junction silicon solar cells. This paper provides the proof-of-concept of a procedure to reduce contact recom ...
