Grain boundaries (GBs) in perovskite polycrystalline films are the most sensitive place for formation of defect states and accumulation impurities. Thus, abundant works have been carried out to explore their properties then try solve induced problems. Currently, two important issues remain. First, role GBs charge carrier dynamics is unclear due component complexity/defect tolerance nature insufficiency testing accuracy. Some conclude that benign, while others consider as recombination centers. Things sure deterioration ion transport decomposition. Second, known hazards GBs, a lot additives added anchoring ions passivate defects. But those works, surfaces treated same manner ignoring fact GB essentially homogeneous junction narrow slender space, surface heterogeneous with stratified structure. In this review, we focus on insight into them. Additionally, also discuss prospects maturity exploration toward upscaling manufacture photovoltaic related optoelectronic devices.

Abstract Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle them compete established photovoltaic technologies. The community relies on the International Electrotechnical Commission (IEC) standard minimum assessment any commercialized cell. In this review, we summarize main degradation mechanisms of results achieving sufficient meet IEC standards. We also limitations evaluating cell commercialization potential within framework current standard, discuss importance outdoor testing.

Decarbonisation plans across the globe require zero-carbon energy sources to be widely deployed by 2050 or 2060. Solar is most available resource on Earth, and its economic attractiveness improving fast in a cycle of increasing investments. Here we use data-driven conditional technology forecasting modelling establish which zero carbon power could become dominant worldwide. We find that, due technological trajectories set motion past policy, global irreversible solar tipping point may have passed where gradually comes dominate electricity markets, without any further climate policies. Uncertainties arise, however, over grid stability renewables-dominated system, availability sufficient finance underdeveloped economies, capacity supply chains political resistance from regions that lose employment. Policies resolving these barriers more effective than price instruments accelerate transition clean energy.

Abstract Although perovskite solar cells (PSCs) are on the road to industrialization, operational stability under high efficiency still needs be improved, and water solubility of lead ions (Pb 2+ ) will cause environmental pollution problems. Herein, it is successfully implanted an environment‐friendly (biodegradability) poly(butylene adipate‐coterephthalate) polymer (PBAT) into film, which can passivate uncoordinated Pb neutral iodine defects material because adequate carbonyl groups benzene rings in PBAT polymer, thereby regulating crystallization film with lower trap density, inhibiting nonradiative recombination improving charge carrier transport. As a result, polymer‐incorporated inverted PSCs achieve optimal conversion efficiencies 22.07% (0.1 cm 2 20.31% (1 ). Meanwhile, incorporated device, after being encapsulated, exhibits prominent improvement high‐efficiency device maximum power point tracking continuous one sunlight illumination, maintaining initial 80% for 3249 h. More importantly, network protect from dissolved by prevent nearly 98% leaking directly immersing polymer‐coated water. Environmental‐friendly molecules provide new hope solving poisoning efficiency.

Abstract External encapsulation technique as a straightforward craft process has been adopted to prevent the infiltration of moisture and oxygen, thereby improving environmental stabilities lead halide perovskite solar cells (PSCs). However, irreversible light‐induced degradation originating from various vacancies ion diffusion or migration inside device cannot be efficiently solved by external encapsulation. Herein, an internal strategy introducing NbCl 5 at buried tin oxide/perovskite interface spin‐casting n ‐butylammonium bromide on top is developed comprehensively passivate hence block channels for migration. The results in better homogeneous electron transport layer effective vacancy passivation simultaneously generates more homogeneous, crystallized vertical direction with significantly reduced residual PbI 2 . Furthermore, fewer oxygen formation ultrathin Nb O interfacial energy level alignment transfer. As result, power conversion efficiency (PCE) resulting PSCs high 24.01%. More importantly, demonstrates excellent stability, retaining 88% its initial PCE maximum point tracking measurement (under 100 mW cm –2 white light illumination ≈55 °C temperature, N atmosphere) after 1000 h.

Abstract Organic–inorganic hybrid perovskite solar cells (PSCs) are regarded as a promising next‐generation photovoltaic technology. However, poor device stability limits their commercialization. Carbon‐based inorganic PSCs (C‐IPSCs) can meet challenge owing to the absence of organic components. Meanwhile, hydrophobic carbon materials hole transport layers and back electrodes simplify fabrication process, decrease costs, protect devices from moisture erosion. Since first attempt for C‐IPSCs in 2016, series strategies have been proposed improve performance, including technique optimization, solvent engineering, composition interface charge layer so on, power conversion efficiency rapidly increased initial 5% exceeding 15%. In this review, recent progress is summarized, existing challenges field discussed, followed by prospect future development.
