Despite the potential of PbS quantum dots (QDs) as sensitizers for quantum-dot-sensitized solar cells (QDSSCs), achieving a high photocurrent density over 30 mA cm(-2) remains a challenging task in PbS-sensitized solar cells. In contrast to previous attempts, where Hg(2+)-doping or multi-step post-treatment is necessary, we are capable of achieving a high photocurrent exceeding 30 mA cm(-2) sim...

Photocatalytic hydrogen production is a promising route to the provision of sustainable and green energy. However, excess addition traditional electron donors as sacrificial agents consume photogenerated holes greatly reduces feasibility this approach for commercialization. Herein, considering abundant hydroxyl groups in cellulose, major component biomass, we adopted glucose (a unit cellulose),...

Antimony sulfide (Sb2S3) is a promising wide-bandgap photovoltaic material, and potential top-cell candidate for next-generation Si-based tandem solar cells. The most widely used electron transport layers in Sb2S3 cells are TiO2 CdS, which present an obvious performance variation open-circuit voltage (V OC) short current (J sc). However, the mechanisms behind disparity because of layer (ETL) ha...

N-type metal oxide solar cells sensitized by infrared absorbing PbS quantum dots (QDs) represent a promising alternative to traditional photovoltaic devices. However, colloidal PbS QDs capped with pure organic ligand shells suffer from surface oxidation that affects the long term stability of the cells. Application of a passivating CdS shell guarantees the increased long term stability of PbS Q...
