Addition of adamantylammonium iodide to hole transport layers enables highly efficient and electroluminescent perovskite solar cells

Michael Graetzel, David Lyndon Emsley, Wolfgang Richard Tress, Jovana Milic, Dominik Józef Kubicki, Mohammad Mahdi Tavakoli

The efficiency of perovskite solar cells (PSCs) is currently limited by non-radiative recombination losses. One potential loss channel consists of electrons recombining at the interface with the hole transport layer (HTL). We synthesized adamantylammonium ...

Promises and challenges of perovskite solar cells

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

The efficiencies of perovskite solar cells have gone from single digits to a certified 22.1% in a few years' time. At this stage of their development, the key issues concern how to achieve further improvements in efficiency and long-term stability. We revi ...
