Proof-of-concept for facile perovskite solar cell recycling

Ulf Anders Hagfeldt, Joachim Maier, Fabrizio Giordano, Othmar Müntener, Norman Pellet, Jeannette Medina Kadro

Perovskite solar cells based on CH3NH3PbI3 and related materials have reached impressive efficiencies that, on a lab scale, can compete with established solar cell technologies, at least in short-term observations. Despite frequently voiced concerns about ...

Ionic Liquid Control Crystal Growth to Enhance Planar Perovskite Solar Cells Efficiency

Michael Graetzel, Shaik Mohammed Zakeeruddin, Kurt Schenk, Ulf Anders Hagfeldt, Michael Saliba, Jingshan Luo, Antonio Abate, Fabrizio Giordano, Juan-Pablo Correa-Baena, Konrad Domanski

Ionic liquids can retard the perovskite crystallization with the aim to form compact films with larger and more uniformly distributed grain size. The ionic liquid driven crystallization is exploited to prepared a record planar perovskite solar cell with st ...

Molecular Engineering of Pyrido[3,4-b]pyrazine-Based Donor-Acceptor-pi- Acceptor Organic Sensitizers: Effect of Auxiliary Acceptor in Cobalt- and Iodine-Based Electrolytes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jean-David Décoppet, Fabrizio Giordano, Bo Liu

Due to the ease of tuning its redox potential, the cobalt-based redox couple has been extensively applied for highly efficient dye-sensitized solar cells (DSSCs) with extraordinarily high photovoltages. However, a cobalt electrolyte needs particular struct ...

Silolothiophene-linked triphenylamines as stable hole transporting materials for high efficiency perovskite solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Michael Saliba, Peng Gao, Antonio Abate, Fabrizio Giordano, Sanghyun Paek, Juan-Pablo Correa-Baena

In this work, we synthesized novel hole transporting materials (HTMs) and studied their impact on the stability of perovskite-based solar cells (PSCs). The steady-state maximum power output of devices in working condition was monitored to assess the stabil ...

Hyperbranched self-assembled photoanode for high efficiency dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Luca Passoni

The photoanode morphology is key for improving photovoltaic performance of dye-sensitized solar cells. On one side, light harvesting depends on its capability of both chemisorbing high quantity of dye and affecting the flow of light in order to enhance its ...
