Perovskite solar cells(PSCs)are taking steps to commercialization.However,the halogen-reactive anode with high cost becomes a stumbling block.Here,the halogen migration in PSCs is utilized to in situ generate a uniform tunneling layer between the hole transport materials and anodes,which enriches the options of anodes by breaking the Schottky barrier,enabling the regular PSCs with both high efficiency and stability.Specifically,the regular PSC that uses silver iodide as the tunneling layer and copper as the anode obtains a champion power conversion efficiency of 23.24%(certified 22.74%)with an aperture area of 1.04 cm^(2).The devices are stable,maintaining 98.6%of the initial effi-ciency after 500 h of operation at the maximum power point with continuous 1 sun illumination.PSCs with different tunneling layers and anodes are fabricated,which confirm the generality of the strategy.

Perovskite solar cells(PSCs)have gained increasing attention due to their excellent photovoltaic performance,achieving certified power conversion efficiency(PCE)of 25.2%.To further enhance PCE and break the Shockley-Queisser limit of the single junction PSCs,great efforts have been made in tandem solar cells based on perovskite,including perovskite/Si,and perovskite/perovskite(all-perovskite).Among them,all-perovskite tandem solar cells exhibit unique advantages of both lowcost fabrication and high efficiency.They have advanced rapidly in these years,due to the realization of stable and efficient narrow-bandgap perovskites.In this work,we review the development of monolithic all-perovskite tandem solar cells and highlight the critical role of narrow-bandgap perovskites in recent progress of all-perovskite solar cells.We also propose our perspective of future directions on this subject.

针对能源利用效率不同区域间的大气污染物协同减排问题,构建区域间纳什讨价还价模型,分析绝对数量、相对比例、经济补偿三种区间协同减排协议的有效性。分析表明:绝对数量与相对比例两种协同减排协议无效,而经济补偿能实现区域间大气污染物的协同减排,且均衡的减排数量和经济补偿金额与发达地区的大气污染物排放经济效用价值系数正相关,与欠发达地区的大气污染物排放效用价值系数负相关。经济发达地区与经济欠发达地区总效用的增加值,总体上随着两地区大气污染物排放经济效用价值系数的增加而增长。

DNA nanostructures have found widespread applications in areas including nanoelectronics and biomedicine.However,traditional DNA origami needs a long single-stranded virus DNA and hundreds of short DNA strands,which make this method complicated and money-consuming.Here,we present a protocol for the assembly of DNA nanoribbons with only four oligonucleotides.DNA nanoribbons with different dimensions were successfully assembled with a 96-base scafford strand and three short staples.These biotinylated nanoribbons could also be decorated with streptavidins.This approach suggests that there exist great design spaces for the creation of simple nucleic acid nanostructures which could facilitate their application in plasmonic or drug delivery.

The concept of travelling wave reactor(TWR)applies the mechanism of self-sustaining and propagating nuclear fission travelling waves in fertile media of 238U and 232Th to achieve very high fuel utilization.Based on this concept,a stepwise radial fuel shuffling strategy was proposed and applied to a sodium-cooled fast reactor(SFR)loading metallic 238U fuel.The multi-group deterministic neutronic code ERANOS with JEFF3.1 data library was used as a basic tool to perform the neutronics and burnup calculations.The inward fuel shuffling calculations were first performed in a 1-D cylindrical case for parametric understanding,and then extended to a 2-D R-Z case.The shuffling calculations for the 1-D and 2-D SFR model yielded some interesting results.The asymptotic keff varied parabolically with the characteristic fluence,while the burnup increased linearly.The highest burnup achieved in 2-D case was 38%.The power peak shifted from the fuel outlet side(core centre)to the fuel inlet side(core periphery)in both 1-D and 2-D cases and the corresponding peaking factor decreased dramatically along with the characteristic fluence.The present research demonstrated that the proposed stepwise radial fuel shuffling in the sodium fast reactor achieved the characteristics of the traveling wave reactor.

Electrochemical hydrogenation(ECH)of biomass-derived platform molecules is a burgeoning route for the sustainable utilization of hydrogen.However,the noble-metal-catalyzed ECH of phenolic compounds suffers from intense competition with hydrogen evolution reaction.We prepared Pt Rh bimetallic nanoparticles dispersed on highly ordered mesoporous carbon nanospheres,which improves the utilization efficiency of adsorbed hydrogen(H_(ad))to ECH in H-UPD region(>0 V vs.RHE).Further analysis reveals(i)the strong overlapping between the d-orbitals of Pt and Rh enhances specific adsorption of phenol;(ii)incorporation of Rh devotes an electronic effect on weakening the alloy-H_(ad)interaction to increase the FE of ECH.DFT calculations confirm the selectivity difference and the ECH parallel pathways:cyclohexanol and cyclohexanone are formed via hydrogenation/dehydrogenation of the intermediate ^(*)C_(6)H_(10) OH.These findings deepen our fundamental understanding of the ECH process,and cast new light on exploration of highly efficient electrocatalysts for biomass upgrading.
