Carrier Transport Layer-Free Perovskite Solar Cells

Power conversion efficiencies (PCEs) of up to 25.5 % have been reported for perovskite solar cells (PSCs). Thus, they have shown great potential for commercial applications. Therefore, simplifying technological process and reducing production costs have be ...

SLC25A51 is a mammalian mitochondrial NAD(+) transporter

Kai Johnsson, Liang Wang

Mitochondria require nicotinamide adenine dinucleotide (NAD(+)) to carry out the fundamental processes that fuel respiration and mediate cellular energy transduction. Mitochondrial NAD(+) transporters have been identified in yeast and plants(1,2), but thei ...

Tailor-Making Low-Cost Spiro[fluorene-9,9 '-xanthene]-Based 3D Oligomers for Perovskite Solar Cells

Ulf Anders Hagfeldt, Liang Wang, Peng Liu, Jiahuan Zhang

The power-conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have increased rapidly from about 4% to 22% during the past few years. One of the major challenges for further improvement of the efficiency of PSCs is the lack of sufficiently good ...

Incorporation of Counter Ions in Organic Molecules: New Strategy in Developing Dopant-Free Hole Transport Materials for Efficient Mixed-Ion Perovskite Solar Cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Liang Wang, Lin Yang, Monica Marcela Lira Cantu, Jiahuan Zhang

Hole transport matertial (HTM) as charge selective layer in perovskite solar cells (PSCs) plays an important role in achieving high power conversion efficiency (PCE). It is known that the dopants and additives are necessary in the HTM in order to improve t ...

From marine plants to photovoltaic devices

Michael Graetzel, Liang Wang, Hong Zhang, Ning Wang

We demonstrated that extracts from sea tangle can serve as a sensitizer, redox couple, as well as a counter electrode material, or even can be fabricated into an "all-natural solar cell". Especially, the carbon counter electrode from sea tangle has achieve ...

Economical Pt-Free Catalysts for Counter Electrodes of Dye-Sensitized Solar Cells

Michael Graetzel, Ulf Anders Hagfeldt, Liang Wang

Three classes (carbides, nitrides and oxides) of nanoscaled early-transition-metal catalysts have been proposed to replace the expensive Pt catalyst as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). Of these catalysts, Cr3C2, CrN, VC(N), VN ...
