Thermostat management is crucial in maintaining safe indoor temperatures. Here we analyse factors that influence thermostat settings in US households during daytime and nighttime hours, with a focus on thermostat type, occupant behaviour, and socio-economic and socio-demographic characteristics. Recommended indoor settings range from 64–75 °F (17.8–23.9 °C) in winter and 75–80.5 °F (23.9–26.9 °C) in summer. For context, data show average daytime thermostat settings of 70.1 °F (21.2 °C) in winter and 72.1 °F (22.3 °C) in summer. Regression results reveal households that manually adjust their thermostat or set it to a single fixed temperature maintain less-efficient temperatures than those relying on smart thermostat automation—up to 2.3 °F (1.3 °C) warmer in winter and 2.2 °F (1.2 °C) cooler in summer. Racial disparities are also evident: Black households set temperatures up to 2.2 °F (1.2 °C) higher in winter and 1.4 °F (0.78 °C) lower in summer than white households. Expanding access to smart technologies and educational initiatives related to thermostat management may improve efficiency and thermal equity.

Antimony chalcogenide (Sb2(S,Se)3) is a promising candidate for next-generation photovoltaic materials due to its optoelectronic properties, high absorption coefficient and material availability. Hydrothermal deposition has advanced the technology, but there is a limited understanding of the underlying reaction mechanisms, often resulting in non-ideal valence band maximum gradient across the absorber thickness and high concentration of deep-level defects. Here we introduce sodium sulfide as an additive in the precursor solution to control reaction kinetics. This strategy enables a more uniform depth-dependent elemental distribution, flattens the unfavourable valence band maximum gradient across the depth and suppresses the formation of deep-level defects. We demonstrate an improvement in Sb2(S,Se)3 material quality, achieving a power conversion efficiency of 11.02%, with a certified value of 10.7 ± 0.37%. This work advances the efficiency for Sb2(S,Se)3 solar cells and provides insights to optimize the hydrothermal synthesis for this technology.

Instability hinders the commercialization of perovskite solar cells. Now, a co-crystal engineering strategy is developed to create a protective two-dimensional perovskite layer on top of a three-dimensional perovskite layer. This approach increases the stability and efficiency of perovskite solar modules, surpassing current photovoltaic standards, in a step towards industrial manufacturing.

While decarbonizing road transport is crucial for global climate goals, there is limited quantitative evidence on the economic viability and life-cycle emissions of low-carbon passenger vehicles in Africa, where motorization is rising. Here we study the economic cost and life-cycle greenhouse gas emissions of low-carbon passenger transport in Africa across six segments in 52 African countries through 2040. Using Monte Carlo and optimization models, we compare the total cost of ownership and life-cycle greenhouse gas emissions of battery electric vehicles powered by solar off-grid systems and synthetic fuelled vehicles to that of fossil-fuelled ones, neglecting policy-induced cost distortions. Whereas past reports suggested fossil fuel vehicles would dominate in Africa by mid-century, our results show that battery electric vehicles with solar off-grid chargers will have lower costs and negative greenhouse gas abatement costs well before 2040 in most countries and segments. Financing is identified as the key action point for governments and global financial institutions to accelerate Africa’s transition to battery electric vehicles with solar off-grid charging offering a cost-effective, viable solution to electricity infrastructure challenges. Decarbonizing road transport is critical, but the costs and emissions of low-carbon vehicles in Africa remain uncertain. The authors show that battery electric vehicles with solar off-grid systems can cost effectively reduce life-cycle emissions well before 2040.

Solar cells based on kesterite materials, Cu2ZnSn(S,Se)4 (CZTSSe), offer a non-toxic, Earth-abundant solution for energy generation. However, they have historically struggled to achieve power conversion efficiencies comparable to those of other thin-film photovoltaic technologies. Here we highlight the critical role of the synthesis and formation pathway of these multinary semiconductors, discussing the challenges associated with kesterite layer fabrication and their impact on device performance. In particular, we discuss how the design of molecular inks in kesterite synthesis is key to overcoming these limitations, unveiling the connections between precursor chemistry, synthesis pathways and the formation of point and extended defects. We discuss how precise control over these factors has enabled kesterite solar cells to exceed 15% efficiency. Building on these advances, we propose strategies to further improve device performance. Finally, the insights presented here provide a framework for the exploration and development of other multinary semiconductor materials. Photovoltaics based on kesterite materials have now achieved 15% efficiency after remaining at lower levels for years. In this Review, Jimenez-Arguijo et al. explore the critical roles of precursor chemistry and the formation pathway in enabling performance improvements in these complex multinary semiconductors.

Individual building-level approaches are needed to understand the full potential of rooftop photovoltaics (PV) at national and regional scale. Here we use the European Digital Building Stock Model R2025, an open-access building-level database, to assess rooftop solar potential for each of the 271 million buildings in the European Union. The results show that potential capacity could reach 2.3 TWp (1,822 GWp residential, 519 GWp non-residential), with an annual output of 2,750 TWh based on current PV technology. This corresponds to approximately 40% of electricity demand in a 100% renewable scenario for 2050. Already by 2030, over a half of buildings with floor area larger than 2,000 m2 could generate most of remaining capacity for the 2030 target with 355 GWp. Across member states, non-residential rooftops could cover 50% or more of their PV targets, with several exceeding 95%. The open-access building-level database offers practical tools to support better decisions, accelerate renewable energy adoption and promote a more decentralized energy system. It is also an enabler for planners and researchers to further explore energy scenarios with high renewable shares. This resource presents an open per-building dataset of rooftop solar photovoltaics potential for the European Union. The results show that potential capacity could cover approximately 40% of electricity demand in a 100% renewable scenario for 2050.

Selenium (Se), the world’s oldest photovoltaic material, is experiencing a resurgence in interest due to its intrinsic wide bandgap of approximately 1.9 eV, making it an ideal photoabsorber for the top cell in tandem solar cells and for indoor photovoltaics. However, the power conversion efficiency of Se solar cells remains constrained by severe non-radiative recombination losses caused by the small grain size (~500 nm) of conventionally thermally annealed Se films. Here we report an illumination-assisted annealing strategy that enables photo-induced crystallization at ambient temperature while suppressing dewetting, followed by subsequent thermal annealing, to fabricate Se films with large grains (~2.7 μm), a low trap-state density (6.9 × 10¹⁴ cm⁻³) and a long carrier lifetime (22.9 ns). The resultant Se solar cells achieve a certified power conversion efficiency of 10.3% with a 1.03 V open-circuit voltage. Unencapsulated devices exhibit negligible performance loss after 1,000 h under maximum power point tracking in ambient conditions. The efficiency of selenium photovoltaics is hindered by the poor crystallization of the Se film. Wen, Li, Lu and colleagues use light to initiate Se crystallization, suppressing dewetting and enabling the formation of a continuous film, which achieves a certified efficiency of 10.3%.

Of the many families of solar absorber materials known, only a handful have been shown to convert sunlight into electricity with power conversion efficiencies above 10%. Now, researchers have pushed selenium photovoltaics past this efficiency threshold by implementing a series of improvements to the material processing and device design.
