11.1 Introduction

A strong feature of hybrid perovskite solar cells is the simplicity of the device structures. By essentially sandwiching a thin hybrid perovskite layer (∼500 nm) between an electron transport layer (ETL) and a hole transport layer (HTL), quite high conversion efficiencies exceeding 20% can be achieved without ...
