The Role of Oxygen Exposure on the Performance of All-Vapor-Processed Perovskite Solar Cells With CuPC Hole Transport Layers

Austin George Kuba

Methylammonium lead iodide (MAPbI(3)) perovskite solar cells were made using an all-vapor process, including two-step close space vapor transport-processed MAPbI(3) absorber and evaporated copper phthalocyanine (CuPC) hole transport layer (HTL). N-i-p sola ...

D-A-D- and A-A-D-Type Cyanopyridone Derivatives as a New Class of Hole-Transporting Materials for Perovskite Solar Cells

Mohammad Khaja Nazeeruddin

The present study focused on the development and characterization of four new low-cost hole-transporting materials (HTMs), ZZ01, DJ01, PR01, and PM01, designed based on the concepts of donor-acceptor-donor (D-A-D) or acceptor-acceptor-donor (A-A-D) for app ...

Additives-free indolo[3,2-b]carbazole-based hole-transporting materials for perovskite solar cells with three yeses: Stability, efficiency, simplicity

Ulf Anders Hagfeldt, Bowen Yang, Jiajia Suo, Yeonju Kim

Indolo[3,2-b]carbazole-based hole transporting materials (HTM1-3) are developed for dopant-free pemvskite solar cells (PSCs). The newly synthesized compounds are studied as alternatives of conventional hole-transporting materials which typically require ad ...

Limits to Electrical Mobility in Lead-Halide Perovskite Semiconductors

Samuel Poncé

Semiconducting polycrystalline thin films are cheap to produce and can be deposited on flexible substrates, yet high-performance electronic devices usually utilize single-crystal semiconductors, owing to their superior charge-carrier mobilities and longer ...

Linear and Time-Resolved THz Spectroscopy of Photonic and Charge Transporting Systems

Jan Cornelius Brauer

Photo-induced charge separation and charge transport are fundamental processes in many energy conversion techniques, where light is converted into chemical energy (PEC), into electrical energy (solar cells) or in the opposite sense if electrical energy is ...
