Negative electricity prices—when consumers are paid to use power—are becoming more frequent worldwide. This counterintuitive phenomenon arises when supply exceeds demand. While negative pricing offers economic potential, little is known about consumer willingness to increase electricity use in response. Prior research has focused on reducing demand during peak-load periods, with limited attention to incentivizing consumption. Here we surveyed 1,918 US residents to examine factors influencing participation in negative price events. Contrary to the low elasticity in traditional demand response programmes, we observe higher responsiveness under negative pricing. Over 75% of respondents indicate a willingness to shift electricity use even during weekdays and late nights. Interestingly, despite the opportunity to profit, most respondents were unwilling to abuse power by overconsumption. Nevertheless, simulations based on reported willingness suggest demand could surge by twofold in over 25% of US counties—and as much as tenfold in some—raising concerns about grid reliability. Consumers are increasingly being paid to use power through negative electricity pricing. Based on a survey in the USA, new research finds that most respondents are willing to shift their electricity use and do not seek to overconsume power, which may inform future power management.

The certified quasi-steady-state efficiency of reported inverted perovskite solar cells (PSCs) has rarely surpassed 26%, primarily attributed to interfacial energy-level misalignment and defect-mediated non-radiative recombination. Here we report a surface-phase-transformation strategy of introducing a minuscule amount of N-methyl pyrrolidone (NMP) into the piperazinium diiodide (PDI)-dissolved isopropanol solution to mitigate these challenges. We demonstrate that NMP induces a distinct crystallization pathway on perovskite surfaces during the post-treatment stage, transitioning from a solvated intermediate phase to the α-phase perovskite, bypassing the conventional δ-intermediate-phase → α-phase route, which improves the crystallinity of perovskite surfaces and reduces contact losses. Moreover, NMP enhances the interaction between PDI and perovskites, further optimizing interfacial band alignment. Consequently, we demonstrate high certified power conversion efficiencies of 26.87% (stabilized efficiency), 23.00% and 29.08% for single-junction PSCs, mini-modules and all-perovskite tandems, respectively. Maximum-power-point tracking retains 96% of initial efficiency after 2,500 h under 1-sun illumination at 65 °C in ambient air. Defective perovskite surfaces limit solar cell efficiency. Liu et al. introduce a small amount of a polar aprotic solvent into the defect passivation solution, enabling surface reconstruction of the perovskite layer and enhancing its overall quality.

Co-design of energy transition pathways with policymakers and the public lead to more significant demand-side reductions than current supply-side-focused policy. When policymakers work directly with academics to re-consider how and why we use energy in our everyday lives, politically feasible, significantly cheaper options with 45% less energy demand are possible.

Demand-side energy reductions have so far received less policy support than supply-side net-zero technologies. Here we undertake a demand-focused process for energy scenario analysis, led by policymakers and evaluated through public dialogue. We codesign, describe and model four societal futures that aim to achieve the UK’s 2050 net-zero target. The uniquely close involvement of policymakers leading the project generates markedly different narratives that reflect policymakers’ concerns while still leading to scenarios with reductions in energy demand of 18–45%—exceeding what policies normally suggest. By 2050, technology-focused systems cost 20–100% more than lower-demand ones. While intensive cocreation requires more complex interactions compared with academic-led research, it provides space for important, and otherwise absent, energy demand conversations. This work demonstrates how engaging policymakers to colead energy scenarios can challenge conventional policy assumptions on energy demand while offering an approach to support global climate mitigation efforts. New research finds that policymakers coleading energy scenario design has the potential both to better align scenarios with policymakers’ priorities and to question current policy, by substantially reducing energy use at half of the cost of technology-focused approaches.

Atomic disorder is a widespread issue in multi-element crystalline materials and poses a critical challenge to the performance of Cu2ZnSn(S, Se)4 (CZTSSe) photovoltaic devices. In particular, Cu–Zn disorder is prevalent in CZTSSe due to its low formation energy, leading to the formation of high-concentration deep defects and severe charge loss. The regulation of this disorder remains challenging because of the trade-off between the thermodynamics of the disorder–order phase transition and the kinetics of atom interchange. Here we introduce additional vacancy defects at the CZTSSe surface via magnesium doping to reduce the energy barrier for atom interchange. This vacancy-assisted approach enhances the kinetics of Cu–Zn ordering, thereby reducing charge loss in the device. As a result, we achieve a power conversion efficiency of 14.9% certified by the Chinese National PV Industry Measurement and Testing Center in CZTSSe solar cells, marking an advancement in the development of emerging inorganic thin-film photovoltaics. Atomic disorder limits the performance of kesterite solar cells. Jinlin Wang et al. introduce surface vacancy defects via magnesium doping, which reduces cation disorder and charge losses, enabling a certified efficiency of 14.9%.

Hydrogen will play a critical role in decarbonizing diverse economic sectors. However, given limited sustainable resources and the energy-intensive nature of its production, prioritizing its applications will be essential. Here, we analyse approximately 2,000 (low-carbon) hydrogen projects worldwide, encompassing operational and planned initiatives until 2043, quantifying their greenhouse gas (GHG) emissions and mitigation potential from a life cycle perspective. Our results demonstrate the variability in GHG emissions of hydrogen applications, depending on the geographical location and hydrogen source used. The most climate-effective hydrogen applications include steel-making, biofuels and ammonia, while hydrogen use for road transport, power generation and domestic heating should be discouraged as more favourable alternatives exist. Planned low-carbon hydrogen projects could generate 110 MtH2 yr−1, emit approximately 0.4 GtCO2e yr−1, and potentially reduce net life cycle GHG emissions by 0.2–1.1 GtCO2e yr−1 by 2043, depending on the substituted product or service. Addressing the current hydrogen implementation gap and prioritizing climate-effective applications are crucial for meeting decarbonization goals. Hydrogen could be crucial for decarbonizing various sectors, but its production is resource intensive, necessitating strategic prioritization of applications. Here the authors analyse approximately 2,000 planned and operational hydrogen projects, quantifying the associated greenhouse gas emissions and identifying climate-effective applications.

Carbon-based perovskite solar cells (C-PSCs) processed at low temperature are gaining attention due to their enhanced stability and cost-effectiveness. However, these benefits are offset by reduced device performance, primarily stemming from inefficient charge transfer between the hole transport layer (HTL) and the carbon electrode. Here we report the use of graphene oxide functionalized with carboxy groups (GO-COOH) as a dopant for the HTL material 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene (Spiro-OMeTAD) to facilitate interfacial charge transfer and immobilize lithium ions to improve both device performance and stability. We demonstrate electron transfer between GO-COOH and Spiro-OMeTAD, where the delocalized electrons in GO-COOH enable p-doping without exposure to oxygen, leading to a strong π–π-conjugated HTL–carbon interface. The formation of Li–C bonds immobilizes the mobile lithium ions, further improving device stability. As a result, the C-PSCs achieve a power conversion efficiency of 23.6%, maintaining 98.7% of their initial performance after 1,000 h of continuous illumination. These results bring the performance of C-PSCs closer to that of devices employing metal electrodes. Perovskite solar cells with carbon electrodes offer advantages in terms of stability and manufacturing cost, but their performance remains limited. Now Wang et al. report an efficiency of 23.6% by doping the hole transport layer with graphene oxide.

Electrolyte design aims to promote ion association (the complexation of cations and anions) to boost lithium-ion battery performance, but safety remains a concern. Now, researchers show that ion association can reduce the onset temperature of exothermic reactions that trigger thermal runaway, and propose a solvent-relay strategy to extend cycle life and improve safety.
