The effects of guanidinium iodide surface treatment (GST) on CH3NH3PbI3 perovskite solar cells with decaphenylcyclopentasilane (DPPS) were investigated. GST decreases the carrier trap density and improves photovoltaic characteristics. X-ray diffraction results showed that lattice constants crystals increased by insertion into methylammonium defects. thermal stability unlaminated devices was tested in air at 85°C. device prepared using exhibited highest conversion efficiency. First-principles calculations supported these experimental results.

Perovskite-CIGS tandem solar cells offer unique benefits, such as high efficiencies and the possibility for cost-effective production on flexible, lightweight substrates. Yet, scaling up of these devices presents challenges, particularly because roughness, solvents, reactions that can impair integrity subcells within configurations. Here, we introduce a metal-free transparent conductive adhesive (TCA) material, implemented via lamination approach, scalable solution facilitates separate fabrication subsequent integration subcells. This TCA not only exhibits promising electrical optical properties but also ensures its process does degrade perovskite. It encapsulation rivaling those commercial encapsulants. By employing this TCA, have attained champion efficiency 20.6% in single-junction semitransparent cells, featuring fill-factor 79.7%. Ultimately, demonstrate compatibility with perovskite-CIGS effectively eliminating need additional while opening pathways recycling perovskite-based tandems.

Lead halide perovskite solar cells (PSCs) have demonstrated power conversion efficiencies comparable to silicon-based cells, yet their instability under environmental stressors, such as humidity, heat, and light, remains a significant barrier commercialization. A primary cause of this is the uncoordinated lead ions (Pb

Despite the unprecedented progress in lead-based perovskite solar cells (PSCs), toxicity and leakage of lead from degraded PSCs triggered by deep-level defects poor crystallization quality increase environmental risk become a critical challenge for eco-friendly PSCs. Here, novel 2D polyoxometalate (POM)-based metal-organic framework (MOF) (C5 NH5 )4 (C3 N2 H5 )2 Zn3 (H8 P4 Mo6 O31 ·2H2 O (POMOF) is ingeniously devised to address these issues. Note that integration POM endows POMOF with great advantages electrical conductivity charge mobility. Ordered induces high-quality film eliminates improve internal stability. The resultant achieve superior power conversion efficiency (23.3%) accompanied improved stability maintains ≈90% its original after 1600 h. Meanwhile, phosphate groups effectively prevents through situ chemical anchoring adsorption methods reduce risk. This work provides an effective strategy minimize sustainable multi-functional POM-based MOF material.
