Formation and Stabilization of Inorganic Halide Perovskites for Photovoltaics

Ulf Anders Hagfeldt, Jiahuan Zhang, Zaiwei Wang, Wanchun Xiang

In the last decade, halide perovskites have emerged as new semiconductors that revolutionize the photovoltaic field. Among this family of materials, all-inorganic halide perovskites are becoming a research paradigm because of their outstanding photophysica ...

Donor Effect on the Photoinduced Interfacial Charge Transfer Dynamics of D−π–A Diketopyrrolopyrrole Dye Sensitizers Adsorbed on Titanium Dioxide

Jacques-Edouard Moser, Ulf Anders Hagfeldt, Heewon Bahng

In this report, we investigate the effects of a strong electron-donating group on the electron injection and recombination processes of diketopyrrolopyrrole (DPP)-sensitized TiO2 films by comparing the dynamics of triphenylamine donor-installed DPP_A and d ...

Unveiling the Concentration-Dependent Grain Growth of Perovskite Films from One- and Two-Step Deposition Methods: Implications for Photovoltaic Application

Mohammad Khaja Nazeeruddin, Yi Zhang, Peng Gao

In order to achieve high-efficiency perovskite solar cells, understanding both the crystal structure and the optoelectronic properties of perovskite layers is of importance. This paper uses crystallization analysis and the modeling study of two different p ...

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

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 ...

Novel Blue Organic Dye for Dye-Sensitized Solar Cells Achieving High Efficiency in Cobalt-Based Electrolytes and by Co-Sensitization

Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Jiahuan Zhang, Kazuteru Nonomura, Yan Hao, Yasemin Saygili, Anna Eriksson, Enrico Polanski

Blue and green dyes as well as NIR-absorbing dyes have attracted great interest because of their excellent ability of absorbing the incident photons in the red and near-infrared range region. A novel blue D-pi-A dye (Dyenamo Blue), based on the diketopyrro ...

Perovskite as Light Harvester: A Game Changer in Photovoltaics

Michael Graetzel, Mohammad Khaja Nazeeruddin

It is not often that the scientific community is blessed with a material, which brings enormous hopes and receives special attention. When it does, it expands at a rapid pace and its every dimension creates curiosity. One such material is perovskite, which ...

Near-infrared sensitization of solid-state dye-sensitized solar cells with a squaraine dye

Michael Graetzel, Mohammad Khaja Nazeeruddin, Amalie Dualeh

Here, we report the use of a squaraine-based dye, JD10, as a near-infrared sensitizer for solid-state dye-sensitized solar cells (ssDSCs). Using spiro-MeOTAD as a hole-transport material, JD10 gave the highest reported power conversion efficiencies (PCE), ...

Panchromatic response composed of hybrid visible-light absorbing polymers and near-IR absorbing dyes for nanocrystalline TiO2-based solid-state solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin

In pursuit of panchromatic sensitizers for mesoporous TiO2-based solid-state solar cells, a near-IR absorbing zinc phthalocyanine dye (coded TT1) was firstly adsorbed over relatively thin (similar to 1 mu m) TiO2 mesoporous films and then a visible-light a ...
