Special Issue Information

Dear Colleagues,

The escalating global energy crisis has accelerated the development of photovoltaic technology (PV), which offers unparalleled advantages in non-pollution and sustainability. Notably, perovskite-based solar cells are regarded as a revolutionary next-generation photovoltaic product due to their high efficiencies, low-cost fabrication, and versatile optoelectronic properties. Over the past decade, considerable efforts, including compositional tuning, interface and defect passivation, device architecture optimization, crystallization dynamics regulation, deposition technique optimization, and durability enhancement, have been directed toward optimizing the performance of perovskite-based solar cells and advancing their commercial viability. However, a significant ideal-reality discrepancy between their actual efficiency and Shockley–Queisser theoretical limit indicates room for further performance improvements. Therefore, it is important to continue enhancing the efficiency and stability of perovskite-based solar cells. This Special Issue aims to foster discussions that will drive perovskite-based solar cells toward practical applications and establish them as a central element in next-generation photovoltaic technologies.

All inorganic CsPbBr3 possesses ideal stability in halide perovskites, but its wide bandgap and relatively poor film quality seriously limit the performance enhancement and possible applications of perovskite solar cells (PSCs). In this work, a triple-functional poly(3-Hexylthiophene) (P3HT) modifier was introduced to realize color-tunable semi-transparent CsPbBr3 PSCs. From the optical perspective, the P3HT acted as the assistant photoactive layer, enhanced the light absorption capacity of the CsPbBr3 film, and broadened the spectrum response range of devices. In view of the hole transport layer, P3HT modified the energy level matching between the CsPbBr3/anode interface and facilitated the hole transport. Simultaneously, the S in P3HT formed a more stable Pb-S bond with the uncoordinated Pb2+ on the surface of CsPbBr3 and played the role of a defect passivator. As the P3HT concentration increased from 0 to 15 mg/mL, the color of CsPbBr3 devices gradually changed from light yellow to reddish brown. The PSC treated by an optimal P3HT concentration of 10 mg/mL achieved a champion power conversion efficiency (PCE) of 8.71%, with a VOC of 1.30 V and a JSC of 8.54 mA/cm2, which are remarkably higher than those of control devices (6.86%, 1.22 V, and 8.21 mA/cm2), as well its non-degrading stability and repeatability. Here, the constructed CsPbBr3/P3HT heterostructure revealed effective paths for enhancing the photovoltaic performance of CsPbBr3 PSCs and boosted their semi-transparent applications in building integrated photovoltaics (BIPVs).
