17.1 Introduction

As thoroughly discussed in the previous chapters, perovskite solar cells made tremendous progress in recent years. However, as for all single‐junction solar cells, their power conversion efficiency () is limited by the detailed balance limit [1], as discussed in Chapter 12. Figure 17.1a shows the two major loss mechanisms of single‐junction solar cells. The solar cell ...
