Strain-induced rubidium incorporation into wide-bandgap perovskites reduces photovoltage loss

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mounir Driss Mensi, Ursula Röthlisberger, David Lyndon Emsley, Pascal Alexander Schouwink, Jing Gao, Felix Thomas Eickemeyer, Michael Allan Hope, Lukas Pfeifer, Nikolaos Lempesis, Virginia Carnevali, Ümmügülsüm Günes, Lorenzo Agosta, Yuxuan Zhang, Likai Zheng, Vladislav Slama, Francesco Biasoni

A-site cation mixing can enhance the photovoltaic performance of a wide-bandgap (WBG) perovskite, but rubidium (Rb) cation mixing generally forms a nonperovskite phase. We report that lattice strain locks Rb ions into the α-phase of the lattice of a triple ...

Active Passivation Charge Transport in n‐i‐p Perovskite Solar Cells Approaching 26% Efficiency

Mohammad Khaja Nazeeruddin

In n‐i‐p planar perovskite solar cells (PSCs), the electron transport layer (ETL) and the hole transporting layer play a crucial role in realizing high power conversion efficiency (PCE). Herein, a TiO2‐SDBA‐SnO2 stacked ETL is reported, where 4,4′‐sulfonyl ...

Embracing wind power in the solar PV-dominated Swiss landscape

Christophe Ballif, Nicolas Würsch, Alejandro Pena Bello, Marine Dominique Cauz

The Swiss energy transition, characterized by the nuclear phase-out, relies mainly on the integration of solar photovoltaic (PV), mostly because wind technology faces challenges in local public acceptance. This study aims to analyse Swiss PV and wind gener ...

Perovskite heteroepitaxy for high-efficiency and stable pure-red LEDs

Mohammad Khaja Nazeeruddin, Shun Tian

Ultrasmall CsPbI3 perovskite quantum dots (QDs) are the most promising candidates for realizing efficient and stable pure-red perovskite light-emitting diodes (PeLEDs)1, 2, 3, 4–5. However, it is challenging for ultrasmall CsPbI3 QDs to retain their soluti ...

GaN Surface Passivation by MoS2 Coating

Jean-François Carlin, Nicolas Grandjean, Danxuan Chen, Mitali Banerjee

In this study, we investigate the impact of two-dimensional MoS2 coating on the optical properties of surface GaN/AlGaN quantum wells (QWs). A strong enhancement in GaN QW light emission is observed with monolayer-MoS2 coating, yielding luminescence intens ...

Pre-annealing for improved LPCVD deposited boron-doped poly-Si hole-selective contacts

Xinyu Zhang, Franz-Josef Haug, Luca Massimiliano Antognini, Josua Andreas Stückelberger

We demonstrate the beneficial effect of a pre-annealing step prior to the boron diffusion on passivation and contact resistivity of industrially LPCVD deposited poly-Si/SiOX hole-selective contacts. We investigate the influence of the pre-annealing tempera ...

Data-driven design of organic electronic materials

Jacob Terence Blaskovits

Singlet fission (SF) is a multiexciton-generating process whereby an excited state singlet (S1) is converted into two lower-energy triplets (T1). The inclusion of a SF-capable material into a photovoltaic device offers the potential for the absorption of p ...
