Introducing back-surface field for efficient inverted CsPbI3

Energy loss at perovskite/electron transporting layer (ETL) interface is one key reason limiting the efficiency of inverted CsPbI 3 perovskite solar cells (PSCs). Here we introduce a back-surface field in inverted PSCs through 4-Imidazoleethylamine (4-IEA) treatment to mitigate such interfacial energy loss. 4-IEA treatment will upshift the Fermi level of CsPbI 3 surface and

Conjugated linker-boosted self-assembled monolayer molecule

This study builds upon the success achieved from commercial self-assembled monolayers (SAMs), such as Me-4PACz, by replacing its flexible butyl linker with a conjugated phenylene ring to form a SAM molecule, Me-PhpPACz, for inverted perovskite solar cells (PSCs).The Me-PhpPACz-derived PSCs exhibited an unprecedented power conversion

Constructing heterojunctions by surface sulfidation for efficient

Perovskite solar cells (PSCs) with high power conversion efficiency (PCE) and stability have been reported in regular n-i-p devices, but inverted p-i-n PSCs that could be easier to use in tandem solar cells usually have lower PCEs (22 to 23%) Li et al. sulfurized a lead-rich layer with hexamethyldisilathiane, and the lead-sulfur bonds shifted the Fermi level of

Progress of inverted inorganic cesium lead halide perovskite solar cells

The inverted inorganic PSCs are mainly focused on CsPbI 3 and CsPbI 2 Br due to their suitable bandgap (1.7 and 1.9 eV for CsPbI 3 and CsPbI 2 Br, respectively) for application in photovoltaic field. Figure 2 summarizes the efficiency evolution of the corresponding inverted PSCs. The first inverted inorganic PSC was proposed by Snaith in 2015, showing an efficiency

Bimolecularly passivated interface enables efficient and stable

Compared with the n-i-p structure, inverted (p-i-n) perovskite solar cells (PSCs) promise increased operating stability, but these photovoltaic cells often exhibit lower power conversion efficiencies (PCEs) because of nonradiative recombination losses, particularly at the perovskite/C 60 interface. We passivated surface defects and enabled reflection of minority

Recent development of the inverted configuration organic solar cells

Poly(3-hexylthiophene) is the most representative conjugated polymer donor material. However, its OSCs application is limited by its relatively wide bandgap ∼2.0 eV and thus lack broad absorption profile to collect a large fraction of the solar spectrum (ca. ≤30%) [53], [54], [55].Furthermore, a relatively high-lying HOMO energy level determines the maximum cell V
