Zn(II) and Cu(II) tetrakis(diarylamine)phthalocyanines as hole-transporting materials for perovskite solar cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Jianxing Xia, Kasparas Rakstys, Cansu Igci, Nadja Isabelle Desiree Klipfel, Pavel Culik, Wei Li

Finding new hole-transporting materials (HTMs) suitable for replacing the state-of-the-art spiro-OMe-TAD is still challenging. In this work, newly synthesized diarylamine-substituted metal phthalocyanines (MPcs, M 1/4 Zn(II) or Cu(II)) functionalized with ...

C-60 Thin Films in Perovskite Solar Cells: Efficient or Limiting Charge Transport Layer?

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Cristina Roldán Carmona, Albertus Adrian Sutanto, Cansu Igci, Nadja Isabelle Desiree Klipfel

In this work, we identify the importance of C-60 and compact-TiO2 (cTiO(2)) as electron transport layers on the device performance of coevaporated n-i-p perovskite solar cells. We found (1) a synergetic effect between both layers when extracting the charge ...

Phase-Pure Quasi-2D Perovskite by Protonation of Neutral Amine

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Hobeom Kim, Cansu Igci, So-Min Yoo, Marc Dessimoz

Phase control of low-dimensional metal-halide perovskites (LDPs) greatly affects their optoelectronic properties, and phase-pure LDPs are desirable to achieve efficient perovskite optoelectronic devices such as solar cells and light-emitting diodes. Herein ...

Phosphine Oxide Derivative as a Passivating Agent to Enhance the Performance of Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Hiroyuki Kanda, Aron Joel Huckaba, Valentin Ianis Emmanuel Queloz, Albertus Adrian Sutanto, Hobeom Kim, Cansu Igci

Defects of metal-halide perovskites detrimentally influence the optoelectronic properties of the thin film and, ultimately, the photovoltaic performance of perovskite solar cells (PSCs). Especially, defect-mediated nonradiative recombination that occurs at ...

Dopant‐Free Hole Transport Materials Afford Efficient and Stable Inorganic Perovskite Solar Cells and Modules

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Hiroyuki Kanda, Yong Ding, Bin Ding, Kasparas Rakstys, Olga Syzgantseva, Cansu Igci, Xianfu Zhang, Cheng Liu

The emerging CsPbI3 perovskites are highly efficient and thermally stable materials for wide-band gap perovskite solar cells (PSCs), but the doped hole transport materials (HTMs) accelerate the undesirable phase transition of CsPbI3 in ambient. Herein, a d ...

Cut from the Same Cloth: Enamine-Derived Spirobifluorenes as Hole Transporters for Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Bin Ding, Kasparas Rakstys, Albertus Adrian Sutanto, Cansu Igci

To attain commercial viability, perovskite solar cells (PSCs) have to be reasonably priced, highly efficient, and stable for a long period of time. Although a new record of a certified power conversion efficiency (PCE) value over 25% was achieved, PSC perf ...

D-pi-A-Type Triazatruxene-Based Dopant-Free Hole Transporting Materials for Efficient and Stable Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Sanghyun Paek, Cristina Roldán Carmona, Kasparas Rakstys, Hobeom Kim, Cansu Igci

Three donor-pi-bridge-acceptor (D-pi-A)-type organic small molecules coded CI-B1, CI-B2, and CI-B3 are designed, synthesized, and used as dopant-free hole transporting materials (HTMs) for perovskite solar cells (PSCs). The strong electron-donating triazat ...

Efficiency vs. stability: dopant-free hole transporting materials towards stabilized perovskite solar cells

Mohammad Khaja Nazeeruddin, Kasparas Rakstys, Cansu Igci

In the last decade, perovskite solar cells have been considered a promising and burgeoning technology for solar energy conversion with a power conversion efficiency currently exceeding 24%. However, although perovskite solar cells have achieved high power ...
