Efficient Perovskite/silicon Tandem with Asymmetric Self-Assembly Molecule

Efficient perovskite/silicon tandem with asymmetric self-assembly molecule

Achieving highly ordered and uniformly covered self-assembly monolayers (SAMs) with optimal packing configuration on textured silicon substrates remains a critical challenge for further improving the efficiency of perovskite/silicon tandem solar cells (TSCs)1-3. Here we design an asymmetric SAM (named as HTL201) featuring anchoring group and spacer flanking a carbazole core, serving as hole selective layer (HSL) for perovskite/silicon TSCs. When…

First attempt to build tandem solar cells based on perovskite, transition metal dichalcogenide

Scientists in India have proposed to design new tandem solar cells using transition metal dichalcogenide as an absorber material for the bottom PV device. Their simulations showed these tandem cells may reach an efficiency of over 35%.Researchers from the Indian Institute of Technology Bhubaneswar have designed a tandem solar cell based on a top perovskite device and a bottom cell relying on transition metal dichalcogenide (TMD). TMDs are two-di…
