Investigation of electrodeposited cobalt sulphide counter electrodes and their application in next-generation dye sensitized solar cells featuring organic dyes and cobalt-based redox electrolytes

Michael Graetzel, Mohammad Khaja Nazeeruddin, Thomas Moehl, Julien Edouard Frey, Simon Mathew

Cobalt sulphide (CoS) films are potentiodynamically deposited on fluorine-doped tin oxide (FTO) coated glass substrates employing one, three and five sweep cycles (CoS-I, CoS-III and CoS-V respectively). Analysis of the CoS-III film by impedance spectrosco ...

Dye-sensitized solar cells using cobalt electrolytes: the influence of porosity and pore size to achieve high-efficiency

Mohammad Khaja Nazeeruddin, Aswani Yella, Pascal Comte, Sadig Aghazada, Simon Mathew

Diffusion impediments in redox shuttles are a major limitation to realizing high power conversion efficiencies (PCEs) in dye sensitized solar cells (DSCs) using cobalt complexes. Mass transport limitations are strongly dependent on the pore size and the po ...

Synthesis, characterization and ab initio investigation of a panchromatic ullazine–porphyrin photosensitizer for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ursula Röthlisberger, Basile Curchod, Magdalena Anna Marszalek, Negar Ashari Astani, Julien Edouard Frey, Simon Mathew

An ullazine unit was employed as a donor moiety in a donor-pi-acceptor (D-p-A) motif, employing the porphyrin macrocycle as a pi-system. Synthesis of this ullazine-porphyrin dyad containing sensitizer (SM63) was achieved and an investigation of the electro ...
