{"title":"Prospective Photovoltaic-Thermoelectric Hybrid System","authors":"G. Min","doi":"10.30919/esmm5e606","DOIUrl":"https://doi.org/10.30919/esmm5e606","url":null,"abstract":"Photovoltaic-thermoelectric (PV-TE) hybrid system is an appealing idea due to its potential to harvest thermal energy produced in photovoltaic conversion process or mitigate the temperature effect through cooling. The rationale for developing PV-TE hybrid system is illustrated in Fig. 1, which depicts three possible strategies that might lead to a higher overall efficiency of the hybrid system than that of photovoltaic system alone. In strategy (a), thermoelectric device is used as a cooler that is in direct contact with the solar cells. Since the solar cells exhibit negative temperature coefficient, reducing the operating temperature of the solar cells could lead to an increase in the power output of the solar cell. In strategy (b), thermoelectric device is arranged in similar manner as strategy (a) but used as a thermoelectric generator. Thermalisation loss inside solar cells will lead to an increase in the temperature of the solar cells, which in turn establishes a temperature difference across the thermoelectric generator. As a result, the waste thermal energy from the solar cell can be utilised by thermoelectric generator to convert into useful electric power. In strategy (c), the solar energy in infrared spectrum, which has no use to solar cells, is separated from the visible spectrum and directed to a thermoelectric generator for power generation. Clearly, these strategies are built on the sound scientific rationales. The key question is if they will lead to a realistic improvement when other influences are taken into consideration. This paper aims to offer critical assessments on the prospect in these research directions.","PeriodicalId":11851,"journal":{"name":"ES Materials & Manufacturing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86976690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the fluorographene (FG) nanosheets with different degrees of fluorination were successfully exfoliated from the corresponding raw graphite fluoride by using a facile low-energy ball milling process and ultrasonic treatment. And then ethylene vinyl acetate copolymer/fluorographene (EVA/FG) composite films were prepared by a knife coating method. The effects of fluorination degree and content of FG on the thermal conductivity and electrical insulation of FG composites were systematically studied. An in-plane thermal conductivity of 52.9 W m -1 K -1 and through-plane thermal conductivity of 2.5 W m -1 K -1 has been achieved in the prepared composite films with the FG content of 70 wt% and the C:F ratio of 1:0.63. The prepared composite films also show excellent thermal stability to withstand repeated cooling and heating, as well as high electrical insulation and good flexibility, which makes the FG composites of great potential usage in the field of intelligent wearable devices, soft robots, flexible electronics, and so on.","PeriodicalId":11851,"journal":{"name":"ES Materials & Manufacturing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89625859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solution based deposition of Sb 2 Se 3 crystals with variation in reaction time found to be playing a significant role in controlling the reaction rate during the deposition of Sb 2 Se 3 films. Temporal evolution of structural, morphological and optical properties of deposited Sb 2 Se 3 films were investigated using X-ray diffraction (XRD), scanning electron microscopy and UV-visible spectroscopy, respectively. Solution deposition of Sb 2 Se 3 films involves two steps: initial nucleation and crystal formation followed by growth to form final films. Increased reaction time from 30 to 120 min, deposited films showed morphological evolution for Sb 2 Se 3 nanocrystals from dense spheres to self-assembled flower-like morphology. In addition, optical energy band gap variation from 1.60 to 1.63 eV, suggest the possibility of crystal size optimization with energy band gap tunability of Sb 2 Se 3 crystals in the visible region. This is also evident from the photoluminescence studies, which reveals the luminescence intensity variation with crystal size of Sb 2 Se 3 as a function of deposition time. Optical and morphological response of Sb 2 Se 3 crystals to the reaction conditions suggests it as a suitable and potential candidate for optoelectronic applications such as photovoltaic cells, electronic nano-devices, fuel cells etc .","PeriodicalId":11851,"journal":{"name":"ES Materials & Manufacturing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90640565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
