Dye-sensitized solar cells for efficient power generation under ambient lighting
Marina Freitag,Marina Freitag,Joël Teuscher,Yasemin Saygili,Xiaoyu Zhang,Fabrizio Giordano,Paul Liska,Jianli Hua,Shaik M. Zakeeruddin,Jacques-E. Moser,Michael Grätzel,Anders Hagfeldt +11 more
TL;DR: In this article, a dye-sensitized solar cell (DSC) that achieves very high power-conversion efficiencies (PCEs) under ambient light conditions is presented.
Journal ArticleDOI
11% efficiency solid-state dye-sensitized solar cells with copper(II/I) hole transport materials
Yiming Cao,Yasemin Saygili,Amita Ummadisingu,Joël Teuscher,Jingshan Luo,Norman Pellet,Fabrizio Giordano,Shaik M. Zakeeruddin,Jacques-E. Moser,Marina Freitag,Anders Hagfeldt,Michael Grätzel +11 more
TL;DR: A record 11% stable solid-state dye-sensitized solar cell under standard air mass 1.5 global is reported using a hole-transport material composed of a blend of amorphous Cu(II/I) conductors that conduct holes by rapid hopping infiltrated in a 6.5 μm-thick mesoscopic TiO2 scaffold.
Journal ArticleDOI
Copper Bipyridyl Redox Mediators for Dye-Sensitized Solar Cells with High Photovoltage.
Yasemin Saygili,Magnus Söderberg,Norman Pellet,Fabrizio Giordano,Yiming Cao,Ana B. Muñoz-García,Shaik M. Zakeeruddin,Nick Vlachopoulos,Michele Pavone,Gerrit Boschloo,Ladislav Kavan,Jacques-E. Moser,Michael Grätzel,Anders Hagfeldt,Marina Freitag +14 more
TL;DR: Two copper bipyridyl complexes are presented as new redox couples for DSCs and the high photovoltaic performance of Cu-based redox mediators underlines the significant potential of the new red ox mediators and points to a new research and development direction for D SCs.
Journal ArticleDOI
Dye-sensitized solar cells under ambient light powering machine learning : towards autonomous smart sensors for the internet of things
Hannes Michaels,Michael Rinderle,Richard Freitag,Iacopo Benesperi,Tomas Edvinsson,Richard Socher,Alessio Gagliardi,Marina Freitag,Marina Freitag +8 more
TL;DR: The field of photovoltaics gives the opportunity to make our buildings "smart'' and our portable devices "independent", provided effective energy sources can be developed for use in ambient indoor environments as mentioned in this paper.
Journal ArticleDOI
High-efficiency dye-sensitized solar cells with molecular copper phenanthroline as solid hole conductor
Marina Freitag,Quentin Daniel,Meysam Pazoki,Kári Sveinbjörnsson,Jinbao Zhang,Licheng Sun,Licheng Sun,Anders Hagfeldt,Gerrit Boschloo +8 more
TL;DR: In this paper, solid-state dye-sensitized solar cells with copper phenanthroline complexes in the solid phase can act as efficient molecular hole transporting material (HTM) for hybrid solar cells.
