A chain is as strong as its weakest link - Stability study of MAPbI(3) under light and temperature

Michael Graetzel, Ulf Anders Hagfeldt, Michael Saliba, Pankaj Kumar Yadav, Amita Ummadisingu, Silver Hamill Turren Cruz, Philippe Jürgen Holzhey

The stability of perovskite solar cells is a key issue for industrial development. One reason for this is the volatile organic methylammonium (MA) cation, which is prone to degas under elevated temperatures from the perovskite. At the same time, small amou ...

Fundamental Issues, Technology Development, and Challenges of Boiling Heat Transfer, Critical Heat Flux, and Two-Phase Flow Phenomena with Nanofluids

John Richard Thome

This paper presents a comprehensive and critical review of studies on nucleate pool boiling heat transfer, flow boiling heat transfer, critical heat flux (CHF), and two-phase flow phenomena with nanofluids. First, general analysis of the available studies ...

Injectable, self-opening, and freestanding retinal prosthesis for fighting blindness made of conjugated polymers

Diego Ghezzi, Kevin Sivula, Marta Jole Ildelfonsa Airaghi Leccardi, Laura Ferlauto

Fighting blindness with retinal prostheses requires challenges not yet achieved: implanting a prosthesis (i) large enough to cover the retinal surface and (ii) embedding a high number of highly dense stimulatory elements. We developed an injectable, self-o ...

Isomer-Pure Bis-PCBM-Assisted Crystal Engineering of Perovskite Solar Cells Showing Excellent Efficiency and Stability

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jingshan Luo, Chenyi Yi, Dongqin Bi, Norman Pellet, Xiong Li, Fei Zhang, Shilong Wang

A fullerene derivative (alpha-bis-PCBM) is purified from an as-produced bis-phenyl-C-61-butyric acid methyl ester (bis-[60]PCBM) isomer mixture by preparative peak-recycling, high-performance liquid chromatography, and is employed as a templating agent for ...

High Temperature-Stable Perovskite Solar Cell Based on Low-Cost Carbon Nanotube Hole Contact

Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski

Mixed ion perovskite solar cells (PSC) are manufactured with a metal-free hole contact based on press-transferred single-walled carbon nanotube (SWCNT) film infiltrated with 2,2,7,-7-tetrakis(N, N-di-p-methoxyphenylamine)-9,90-spirobifluorene (Spiro-OMeTAD ...

Reduction in the Interfacial Trap Density of Mechanochemically Synthesized MAPbI(3)

Shaik Mohammed Zakeeruddin, Michael Saliba, Pankaj Kumar Yadav, Daniel Prochowicz

Organo-lead halide perovskites have emerged as promising light harvesting materials for solar cells. The ability to prepare high quality films with a low concentration of defects is essential for obtaining high device performance. Here, we advance the proc ...

Over 20% PCE perovskite solar cells with superior stability achieved by novel and low-cost hole-transporting materials

Shaik Mohammed Zakeeruddin, Jingshan Luo, Chenyi Yi, Dongqin Bi, Norman Pellet, Xiong Li, Fei Zhang, Hongwei Zhu, Shilong Wang, Ziyun Wang

The exploration of alternative low-cost molecular hole-transporting materials (HTMs) for both highly efficient and stable perovskite solar cells (PSCs) is a relatively new research area. Two novel HTMs using the thiophene core were designed and synthesized ...

Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance

Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Jiyoun Seo, Amita Ummadisingu, Taisuke Matsui

All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a "cation cascade" to create perovskite mat ...
