Photoelectrochemical Cell Engineering for Solar Energy Conversion

Dan Zhang

Solar energy is the most abundant energy source, harnessing solar energy holds the solution to the challenge of increasing global energy demand and reducing our dependence on fossil fuels. Photovoltaics which directly convert solar energy into electricity ...

EPFL2023

The teachings herein relate to hole transport compounds containing cyclobutyl moieties that can be made into organic hole conductors and hole transport materials. Furthermore, optoelectronic and photoelectrochemical devices, in particular photovoltaic devi ...

Controlled crystallization and surface engineering of mixed-halide y-CsPbI2Br inorganic perovskites via guanidinium iodide additive in air-processed perovskite solar cells

Mohammad Khaja Nazeeruddin

In this report, we demonstrate enlarged grain size (up to-3 lm) in ambient-stable black c-phase CsPbI2Br thin films through the regulated addition of guanidinium iodide (GAI) as an effective volatile additive. Nuclear magnetic resonance (NMR) and X-ray pho ...

Molecular Engineering of Fluorene-Based Hole-Transporting Materials for Efficient Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Albertus Adrian Sutanto, Nadja Isabelle Desiree Klipfel

New Spiro-OMeTAD analogues and the simpler "half" structures with the terminated methoxyphenyl and/or carbazolyl chromophores are successfully synthesized under Hartwig-Buchwald amination conditions using commercially available starting materials. New fluo ...

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 ...
