Emerging photovoltaics for outer space applications are one of the many examples where radiation hard molecular semiconductors essential. However, due to a lack general design principles, their resilience against extra-terrestrial high-energy can currently not be predicted. In this work, discovery materials is accelerated by combining strengths high-throughput, lab automation and machine learning. This way, large material library more than 130 organic hole transport automatically processed, degraded, measured. The degraded under ultraviolet-C (UVC) light in nitrogen atmosphere, serving as conditions electromagnetic hardness tests. A value closely related differential quantum yield photodegradation extracted from evolution UV–visible (UV–vis) spectra over time used stability target. Following procedure, ranking spanning 3 orders magnitude was obtained. Combining Gaussian Process Regression based on predictors structural fingerprints manual filtering features, structure–stability relations UVC stable could found: Fused aromatic ring clusters beneficial, whereas thiophene, methoxy vinylene groups detrimental. Comparing UV–vis film solution, bond cleavage made out leading degradation mechanism. Even though principle break most bonds, able distribute dissipate energy well enough so that chemical structures remain stable. established predictive model quantifies effect specific features stability, allowing chemists consider strategy. future, larger data set will allow inversely which show high performance at same time.

Flexible perovskite solar cells (F-PSCs) have attracted enormous research interest in wearable and portable electronics because of their lightweight, high flexibility portability. However, power conversion efficiency (PCE) stability still lag far behind rigid devices the soft inhomogeneous nature flexible substrate utilized F-PSCs. Herein, we introduce MeO-2PACz as self-assembled monolayers (SAMs) to modify perovskite/HTL (hole transport layer) interface F-PSCs high-quality thin films are grown. In addition, owing coordination reaction between phosphonic acid group Pb2+ SAMs, defects lattice passivated effectively, trap states probability trap-assisted nonradiative recombination reduced. Finally, impressive PCE 15.34% is achieved with superior SAM-modified device, compared control device a 13.27%. Through this work, provide valuable insights references for further investigation utilization SAMs inverted F- PSCs applications.

Organic solar cells (OSCs) are one of the most promising emerging photovoltaic technologies due to rapid increase in efficiency recent years. While efficiencies over 20% have been reported laboratory scale devices using conventional (p-i-n) structure, OSCs with inverted (n-i-p) structures still underperform, reaching values around 18%. Tin oxide (SnO2) has recently emerged as a transport layer for OSCs. Yet, some reproducibility challenges shown by literature hindered full adaptation this electron (ETL) organic cell community. This Perspective evaluates current status investigation SnO2 OSCs, focusing on its integration into state-of-the-art systems and highlighting toward implementation. We examine which strategies lead efficient stable give critical view whether material can soon become next benchmark

Perovskite solar cells have garnered significant attention due to their outstanding optoelectronic properties, ease of fabrication, and cost-effectiveness, making them a promising candidate for next-generation photovoltaic technologies. However, CsPbIBr2-based perovskites currently face critical challenges regarding limited efficiency relatively poor long-term stability, hindering broader commercial applications.

Further optimization was achieved through innovative incorporation trimesoyl chloride (TMC) doping into perovskite precursor solution. The optimized solution subsequently processed using spin-coating annealing method, resulting in high-quality CsPbIBr2 thin films with improved properties. experimental results demonstrated remarkable enhancement power conversion (PCE), an increase from initial value 6.2% up 10.2%.
