Abstract Over the last decade, perovskite solar cells (PSCs) have drawn extensive attention owing to their high power conversion efficiency (single junction: 26.1%, perovskite/silicon tandem: 33.9%) and low fabrication cost. However, short lifespan of PSCs with initial still blocks practical applications. This operational instability may originate from intrinsic extrinsic degradation materials or devices. Although lifetime has been prolonged through component, crystal, defect, interface, encapsulation engineering, so on, systematic analysis failure regularity for perspective devices against multiple operating stressors is indispensable. In this review, we start elaboration predominant pathways mechanism under working stressors. Then strategies improving long‐term durability respect fundamental materials, interface designs, device summarized. Meanwhile, key results discussed understand limitation assessing stability, potential applications in indoor photovoltaics wearable electronics are demonstrated. Finally, promising proposals, encompassing material processing, film formation, strengthening, structure designing, encapsulation, provided improve stability promote commercialization. image

Indoor photovoltaics (IPV) hold enormous market potential driven by the rising demand for perpetual energy sources to power various small electrical devices and especially Internet of things (IoT) devices. Perovskite solar cells (PSCs) offer exciting prospects this role. This study sets out deepen our knowledge PSC performance under realistic indoor conditions. For purpose, we designed an monitoring system that maintains four at their maximum points simultaneously logs environmental Throughout a 12-month period, monitored behavior three PSCs one crystalline silicon cell (c-Si SC), all with active area approximately 1 cm2. Measured daily yields in conjunction comparative overview minimum requirements different wireless technologies indicate single cm2 should be enough IoT device available short-range, low-power on most days year, fact confirmed prototype device. There are, however, few every year when would not even point tracking, highlighting need least some storage capacity. Solar orientation dependence measurements demonstrated 36% advantage optimal 72% drop worst compared horizontal orientation. A one-year yield results show remarkable three-to-one favor best (148.8 mWh/cm2) over c-Si SC (46.0 mWh/cm2). The also retained its initial throughout simple edge-sealing encapsulation.

The poor film stability of Sn-Pb mixed perovskite and the mismatched interface energy levels pose significant challenges in enhancing efficiency tin–lead (Sn-Pb) solar cells. In this study, polyvinylpyrrolidone (PVP) is introduced into PVK precursor solution, effectively overall film. This improvement achieved through formation robust coordination bonds between carbonyl (C=O) pyrrole ring undercoordinated SnII PbII, thereby facilitating passivation defects. Furthermore, introduction PVP inhibits oxidation tin (Sn), n-type characteristics adjustment level proves instrumental reducing loss, subsequently improving charge transfer mitigating device recombination. Consequently, cells incorporating achieve an outstanding champion power conversion (PCE) 21.31%.

Perovskite solar cells (PSCs) stand at the forefront of advanced optoelectronic devices because their high theoretical power conversion efficiency, cost-effectiveness, and broad application potential. However, as a crucial component in high-performance PSCs, highly toxic lead may leak from discarded PSCs cause environmental health risks. Implementing effective recovery is for sustainable development PSC industry. Existing methods commonly use organic solvents leaching reagents, i.e., dimethyl formamide sulfoxide, impeding potential recycling technologies. This study proposes facile ultrasonic water technique effectively recovering glass substrate PSCs. During process, perovskite layer undergoes rapid degradation, generating PbI2. Most PbI2 dissolves water, yielding solution containing low concentration, while minor fraction converted into insoluble Pb(OH)I particles. The cumulative Pb removal ratio first two cycles processes can reach 99.84%. High-purity (>99.9 wt %) crystals could be synthesized through an evaporation–crystallization step. vital strategy management photovoltaic without addition any solvents.

Abstract In recent years, carbon‐based printable mesoscopic perovskite solar cells (p‐MPSCs) without hole transport layers have garnered considerable interest because of their outstanding benefits in terms stability and cost. However, the use carbon electrodes instead materials noble metal leads to energy level mismatch, which limits power conversion efficiency (PCE) p‐MPSCs. this work, a molecular doping strategy is proposed employing cyclopentylmethanamine passivate surface subsurface crystal defects while inducing an shift toward p‐type region within electrodes. This approach facilitates formation homojunction at micro‐interfaces between perovskites. Results demonstrate that optimizes internal alignment devices, thereby increasing driving force for transfer Ultimately, devices optimized through increase PCE from 17.50% 19.50% retaining over 92% initial after 150 days air ambiance. study provides straightforward effective designing high‐efficiency stable
