Possible role of power-to-vehicle and vehicle-to-grid as storages and flexible loads in the German 110

Erik BLASIUS

Frontiers in Energy 2017, Volume 11, Issue 2,   Pages 146-154 doi: 10.1007/s11708-017-0475-5

Abstract: The sectoral coupling of road traffic (in form of E-Mobility) and electrical energy supply (known as power-to-vehicle (P2V), vehicle-to-grid (V2G) is discussed as one of the possible development concepts for the flexible system integration of renewable energy sources (RES) and the support of the objectives of the German energy transition (aka. Energiewende). It is obvious that E-mobility, which shall produce as few emissions as possible, should be based on the exclusive use of renewable energies. At the same time, the E-mobility can help to reduce the negative effects of the grid integration of RES to the distribution grids. However, this assumes that the electric vehicles are smart integrated to the grids where they charge, meaning that they must be able to communicate and be controllable. Because per se unplanned and uncontrollable charging processes are harmful for the grid operation, especially if they occur frequently and unexpected in similar time periods, the effects can hardly be controlled and can lead to serious technical problems in practical grid operation. This paper provides an insight into the current development of E-mobility in Germany. The insight will be matched with the German development of the RES. By the combination of both sectors, the possible role of the E-mobility for the distribution grid will be depicted, which can have positive and negative aspects.

Sustaining health workforce recruitment and retention in township hospitals: a survey on 110 directors

Jingmin Zheng,Jie Li,Xingxing Jiang,Bin Zhang

Frontiers of Medicine 2015, Volume 9, Issue 2,   Pages 239-250 doi: 10.1007/s11684-015-0392-0

Abstract:

Township hospitals, the main provider of rural primary healthcare in China, are severely understaffed. International studies on factors influencing rural working are increasing; however, studies on factors affecting the recruitment and retention of health workers in Chinese township hospitals are limited. The current study aims to understand the motivation of health workers and arrive at a systematic framework of pluralistic factors that would help support health workers in terms of receiving posts and remaining in posts in township hospitals. A three-stage integrated quantitative and qualitative methodology was employed. First, a survey on 120 directors of township hospitals was conducted to learn the latest status of health workers in township hospitals and distinguish existing problems. Second, after sending these problems back to the directors, an open-ended pen-and-paper survey was conducted to ask the directors to identify the factors influencing the attraction and retention of health workers in township hospitals. Third, four focus groups were conducted to gauge the underlying reasons. Five problems from the questionnaire survey were recognized, and numbers of thematic factors were identified at the individual, professional, and treatment environment from the pen-and-paper survey and focus group. Similar to other studies, this framing of both non-financial and financial elements affected the attraction and retention of health workers in township hospitals, thereby filling the gap in a Chinese context. Although several factors had been recognized earlier, our findings further highlighted the importance of these factors. Meanwhile, the factors identified in this study were barely explored in literature. This paper identifies and develops multi-faceted factors to call for a bundled package of multidimensional incentives if decision-makers get interested. The evidence-based findings in our study can be used to provide China-specific policy recommendations on how to recruit and retain health workers in rural areas of China.

Enhanced performance of NiF/BiVO photoanode for photoelectrochemical water splitting

Frontiers in Energy 2021, Volume 15, Issue 3,   Pages 760-771 doi: 10.1007/s11708-021-0781-9

Abstract: The serious surface charge recombination and fatigued photogenerated carriers transfer of the BiVO4 photoanode restrict its photoelectrochemical (PEC) water splitting performance. In this work, nickel fluoride (NiF2) is applied to revamp pure BiVO4 photoanode by using a facile electrodeposition method. As a result, the as-prepared NiF2/BiVO4 photoanode increases the dramatic photocurrent density by approximately 180% compared with the pristine BiVO4 photoanode. Furthermore, the correlative photon-to-current conversion efficiency, the charge injection, and the separation efficiency, as well as the hydrogen generation of the composite photoanode have been memorably enhanced due to the synergy of NiF2 and BiVO4. This study may furnish a dependable guidance in fabricating the fluoride-based compound/semiconductor composite photoanode system.

Frontiers in Energy 2017, Volume 11, Issue 1,   Pages 78-84 doi: 10.1007/s11708-016-0435-5

Abstract: n-type CZ-Si wafers featuring longer minority carrier lifetime and higher tolerance of certain metal contamination can offer one of the best Si-based solar cells. In this study, Si heterojuction (SHJ) solar cells which was fabricated with different wafers in the top, middle and tail positions of the ingot, exhibited a stable high efficiency of>22% in spite of the various profiles of the resistivity and lifetime, which demonstrated the high material utilization of n-type ingot. In addition, for effectively converting the sunlight into electrical power, the pyramid size, pyramid density and roughness of surface of the Cz-Si wafer were investigated by scanning electron microscope (SEM) and transmission electron microscope (TEM). Furthermore, the dependence of SHJ solar cell open-circuit voltage on the surface topography was discussed, which indicated that the uniformity of surface pyramid helps to improve the open-circuit voltage and conversion efficiency. Moreover, the simulation revealed that the highest efficiency of the SHJ solar cell could be achieved by the wafer with a thickness of 100 µm. Fortunately, over 23% of the conversion efficiency of the SHJ solar cell with a wafer thickness of 100 µm was obtained based on the systematic optimization of cell fabrication process in the pilot production line. Evidently, the large availability of both n-type ingot and thinner wafer strongly supported the lower cost fabrication of high efficiency SHJ solar cell.
