This research focuses on the critical balance between efficiency (PCE) and average visible transmittance (AVT) necessary for the development of semi-transparent PSCs. Through comprehensive investigation, two perovskites, MAPbI3 and MAPbBr3, are examined for their respective advantages of high PCE and transparency. A series of simulations are conducted to analyze the impact of perovskite thickness on the properties of the PSC. The study analyzes the compatibility of different charge transport layers with perovskites to enhance carrier flow and reduce recombination at heterojunction. Furthermore, the effect of the work-function of transparent conductive oxide electrode on the performance of the PSCs is investigated. The findings show that an optimal range of perovskite thickness that achieves PCE of over 10% while maintaining an AVT above 20% offers a viable solution for BIPV. For applications where visual transparency is crucial, the SnO2/MAPbBr3/CuSCN presents a compelling choice with AVT of 29.2% along with PCE of 10.72% at 440 nm thickness. In contrast, for applications requiring higher PCE, the SnO2/MAPbI3/CuSCN stands out with the PCE of 19.22% and AVT of 20% at 250 nm thickness.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This boost in catalytic performance is achieved by simply creating a static distortion in the rhombohedral unit cell by replacing a small proportion of a small-size nondegenerate Ni (69 pm) with a large-size degenerate Cu (73 pm). The materials are synthesized by using a simple sol–gel method. The appropriate doping amount of Cu facilitates the better separation of intrinsic charge carrier pairs by inhibiting their recombination. The photocatalytic and electrochemical activities of durable materials in aqueous MB dye (10 ppm) and KOH (1 molar) electrolyte solutions are found to be directly associated with this improvement in inherent charge carrier transfer characteristics. The enhanced photodissociation of MB dye (42–56%) and specific capacitance (381–450 F g−1) in a KOH (1 molar) electrolyte are in full accord with the investigations carried out using crystallographic and optoelectronic analysis, charging–discharging measurements, and electrochemical impedance (EIS) spectroscopy investigations. Same material with high textural surface areas or controllable particle morphologies might show a far better photo/electrocatalytic performance in a variety of practical applications.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, an interfacial engineering strategy for the development of bimetallic Co–Ni nanoparticles on graphitic carbon nitride (g-C3N4) using ultrasonication followed by coprecipitation is conveyed. These nanoparticles demonstrate high efficacy as bifunctional electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline conditions. Co–Ni nanoparticles on graphitic carbon nitride demonstrate an increased surface area via ultrasonication and subsequent coprecipitation. The g-C3N4 combined with Co–Ni nanoparticles leads to the development of bifunctional catalysts that exhibit significant efficiency in both HER and OER, and their interfacial properties are investigated for the first time. The chemical composition and morphology of g-C3N4 integrated with Co–Ni nanoparticles significantly influence the modulation of redox-active sites and the facilitation of electron transfer, resulting in improved splitting efficiency. The interactions between the Co–Ni bimetal and g-C3N4 demonstrate exceptional electrochemical performance for water splitting. Consequently, the 20% 20–Co–Ni–graphitic carbon nitride electrode demonstrated superior HER performance, comparable to the other electrodes. In the results, it is indicated that an increased molar ratio of Co and Ni incorporated in graphitic carbon nitride significantly improves HER performance.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that the refractive index (RI) ranges from 1.8 to 2.3 with changing gas compositions. Fourier transform infrared Spectroscopy reveals shifts in [SiNH] and [SiH] stretching modes, indicating changes in hydrogen passivation and nitrogen incorporation. Hydrogen bonding densities of [SiH] and [SiNH] correlate positively with the RI. For example, the hydrogen bonding density [NH] ranges from 4.53 × 1023 to 6.32 × 1023 cm−3 for [SiNH] bonds while [Si-H] varies from 6.93 × 1023 to 1.06 × 1024 cm−3.

The present investigation focuses on the development of aqueous-based nanofluids comprising multiwalled carbon nanotubes (MWCNTs) with and without surfactants to enhance the capacity of photothermal conversion in direct absorption solar collectors. To improve the stability of the nanofluid, the gum Arabic (GA) and polyvinyl alcohol (PVA) are used as the surfactants. The stable nanofluid was characterized using UV-visible spectroscopy, zeta potential, fourier-transform infrared spectroscopy, field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy (EDS) analysis. The results indicated that the thermal conductivity was enhanced by 94.57% and 91.19% for the MWCNT/GA/deionized (DI) water and MWCNTs/PVA/DI water based nanofluids in presence of surfactants at 90 °C and 0.02 wt%. The presence of surfactant in MWCNTs/DI water nanofluids exhibit excellent stability and enhanced MWCNTs dispersion. In the photothermal response analysis, the highest temperature of 62.8 °C, which is 16 °C higher than the base fluid, is obtained from 0.02wt% MWCNT/GA nanofluid. The highest efficiency of 27.94% is recorded when 0.02wt% MWCNT/GA nanofluid is used, which shows 71.24% enhancement as compared to the DI water after exposure of 30 minutes under solar irradiation. The use of MWCNTs/GA nanofluid as light-absorbing working fluids in solar collectors is encouraged in the present investigation.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collecting renewable energy in the farmland environment to power the detector will provide a feasible approach. Therefore, a triboelectric-photovoltaic hybrid generator (WS-TPHG) is proposed to collect solar and wind energy efficiently. The generator structure includes a photovoltaic panel (PV) and a wind-driven triboelectric nanogenerator (W-TENG). The switching function of the power supply can be realized through the power management circuit. In the case of sufficient light, the detector is powered by PV steadily, and in the case of insufficient light, the detector is powered by W-TENG via the switching function. The PV can supply a stable voltage of 8.1 V, and the open-circuit voltage (VOC) of W-TENG can reach 478.6 V at 180 rpm. The results verify that the detection of temperature, humidity, and salinity can be successfully achieved through the detector which is powered by WS-TPHG.
