Perovskite solar cells (PSCs) with LiTFSI-doped Spiro-OMeTAD as the hole transport layer (HTL) generally require aging in the air to achieve high efficiency (a.k.a. aging-induced efficiency rising), but attention is rarely paid to the synergistic effects of temperature and humidity during the ambient aging. In this work, based on the …

Existing types of solar cells may be divided into two distinct classes: conventional solar cells, such as silicon p−n junctions, and excitonic solar cells, XSCs. Most organic-based solar cells, including dye-sensitized solar cells, DSSCs, fall into the category of XSCs. In these cells, excitons are generated upon light absorption, and if not created directly at …
