Summary: Metal-oxide-based charge-transport layers are crucial for the development of perovskite solar cells, but the metal-oxide/perovskite interfaces often have defects that hinder charge transfer and cause non-radiative recombination. This review explores the challenges associated with these interfaces and proposes solutions using molecular engineering, such as self-assembled monolayers, to improve their performance and commercial viability.

Summary: The study found that solar cells with ZnO nanowires embedded TiO2 outperformed those with pure TiO2 or pure ZnO, with a power conversion efficiency as high as 10.53%. The enhanced performance is attributed to the synergistic effect of both TiO2/ZnO constituent properties, which optimize electron transport, light harvesting, and overall photovoltaic performance.

Summary: Efforts are being made to develop lead-free perovskite solar cells (PSCs) as concerns about the toxicity of lead hinder its large-scale application. Among the alternatives, tin-based perovskites, specifically CsSnI3 perovskite, show great promise due to their ideal properties. Despite achieving an efficiency of 10.1%, there is still room for improvement considering the theoretical efficiency of over 30%. This article summarizes the properties of CsSnI3 perovskite, provides insights into the challenges hindering efficiency improvements, discusses device engineering strategies, and highlights the remaining challenges and future perspectives for highly efficient CsSnI3 PSCs.

Summary: Using a thermally stable ionic liquid [PPN][TFSI], the high-temperature solid-state reaction between Cs4PbI6 and DMAPbI3 can be retarded, enabling the preparation of high-quality and large-area CsPbI3 films. [PPN][TFSI] increases the formation energy of superficial vacancies and prevents phase degradation of CsPbI3. The resulting PSCs achieved a power conversion efficiency of 20.64% (certified 19.69%) with long-term operational stability over 1000 hours. A record efficiency of 16.89% for an all-inorganic perovskite solar module was achieved, with an active area of 28.17 cm2.

Summary: Continuous light illumination causes over 1% contraction in the out-of-plane direction in two-dimensional hybrid perovskites, which is reversible and strongly dependent on specific superlattice packing. Positive charge accumulation enhances the bonding character of inter-slab I-I interactions and activates out-of-plane contraction.

Summary: Although zinc oxide is widely used in organic solar cells, its light-soaking issues can lead to reversible degradation and incorrect stability measurements. The re-adsorption of oxygen trapped at the interface of ZnO causes this reversible aging, which can be undone with a UV exposure. However, this UV pretreatment compromises device efficiency and production in an oxygen-free environment.

Summary: Organic solar cells (OSCs) have made significant progress in recent years, with breakthroughs in power conversion efficiency, flexible devices, and large area modules. The cathode interlayer (CIL), a crucial component in OSCs, plays a vital role in electron extraction and hole blocking. Traditional CIL materials have drawbacks, prompting research into hybrid CIL materials to combine advantages and reduce disadvantages. This review summarizes recent research progress on hybrid CILs and aims to inspire further innovation in this area, which would greatly benefit the development of OSCs.

Summary: Starch is a sustainable biopolymer that can replace petrochemical-based plastics, but it needs to be processed and treated to become thermoplastic starch. By adding microcellulose or nanocellulose to thermoplastic starch through melt mixing, large-scale production can be achieved. This review compiles studies on the effect of plasticizers and different cellulosic fillers on the properties of thermoplastic starch obtained by melt mixing.
