Phosphonic Acid Modification of the Electron Selective Contact: Interfacial Effects in Perovskite Solar Cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Juan-Pablo Correa-Baena, Silver Hamill Turren Cruz, Rebecca Hill

The role electron-transport layers (ETLs) play in perovskite solar cells (PSCs) is still widely debated. Conduction band alignment at the perovskite/ETL interface has been suggested to be an important role for the performance of the solar cells. However, l ...

How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers

Wolfgang Richard Tress, Simone Meloni, Björn Niesen, Juan-Pablo Correa-Baena, Zaiwei Wang, Chien-Jen Yang, Mozhgan Yavari, Firouzeh Ebadi Garjan

One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high luminescence yields and photovolt ...

Migration of cations induces reversible performance losses over day/night cycling in perovskite solar cells

Mohammad Khaja Nazeeruddin, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Filippo de Angelis, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Silver Hamill Turren Cruz, Taisuke Matsui

Perovskites have been demonstrated in solar cells with a power conversion efficiency of well above 20%, which makes them one of the strongest contenders for next generation photovoltaics. While there are no concerns about their efficiency, very little is ...

The rapid evolution of highly efficient perovskite solar cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Tor Jesper Jacobsson

Perovskite solar cells (PSCs) have attracted much attention because of their rapid rise to 22% efficiencies. Here, we review the rapid evolution of PSCs as they enter a new phase that could revolutionize the photovoltaic industry. In particular, we describ ...

Changes from Bulk to Surface Recombination Mechanisms between Pristine and Cycled Perovskite Solar Cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Juan-Pablo Correa-Baena, Silver Hamill Turren Cruz

Several aspects on the photophysical characterization of lead halide hybrid organic inorganic perovskite solar cells remain unsolved. It has been observed that ionic transport and polarization of the interfaces cause very slow changes that interfere with t ...

Identifying and suppressing interfacial recombination to achieve high open-circuit voltage in perovskite solar cells

Wolfgang Richard Tress, Ulf Anders Hagfeldt, Michael Saliba, Antonio Abate, Juan-Pablo Correa-Baena, Konrad Domanski, Silver Hamill Turren Cruz, Elham Halvani Anaraki

With close to 100% internal quantum efficiency over the absorption spectrum, photocurrents in perovskite solar cells (PSCs) are at their practical limits. It is therefore imperative to improve open-circuit voltages (VOC) in order to go beyond the current 1 ...
