We thoroughly review the existing literature on reliability, maintenance and maintenance strategies for PV plants. The model is applied to ground-mounted solar PV plants of three different sizes: 1, 10, and 100 MWp. The analysis compares immediate corrective maintenance with maintenance strategies of different periodicity (weekly, bi-weekly, and monthly). Simulations take the driving time of the service team and the operation of a spare parts inventory into account. We further analyze the impact of hourly spot prices in contrast to constant prices (feed-in tariffs). We find that corrective maintenance is the most cost-effective strategy. If the service journey takes six hours instead of one hour, corrective maintenance becomes more expensive than weekly periodic maintenance. For a three-hour journey, the size of the PV plant matters. If corrective maintenance is adopted, the establishing of a spare parts inventory should be considered. When volatile hourly spot prices are considered, we find that opportunity costs are lowest (highest) when service teams operate at 8 pm (8 am), irrespective of the day of the week, whereas maintenance events scheduled for Wednesdays at 8 am or 2 pm are, given current EPEX spot prices, the most cost-effective in terms of total costs.","PeriodicalId":158283,"journal":{"name":"ChemRN: Solar & Solar Thermal Energy (Topic)","volume":"1006 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123106254","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}

Those carbon byproducts are: soots (biomass, evaporated carbon, etc.) as well as morphed graphenes. Our results cover optical characterization to demonstrate their suitability of those materials as heat capacitors and heat convertors. Our raw materials are sustainable and currently considered environmental pollutants that require true attention to minimize global warming. Fortunately, they are ideal candidates to reduce the carbon footprints and can contribute towards a true net-zero environmental transition. We explore and demonstrate that soots are among the most competitive materials to transform solar energy into heat due to their absorption capacity, and durability. These materials are more competitive then commercial products and other known solar convertors demonstrating the superior thermosolar benefits. The best candidate is biomass with solar absorptivity, light emission and cost reduction of 96, 15 fold and 85%, respectively, when compare to commercial products. Biomass and soot have comparable or better solar conversion characteristics, and sustainability than pristine carbon nanostructures and they are 3+ orders of magnitude cheaper.","PeriodicalId":158283,"journal":{"name":"ChemRN: Solar & Solar Thermal Energy (Topic)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122492745","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}

Complementary to existing studies, we explore the influence of PV projects on sustainable development benefits for rural and further introduce the projects designation event into the model to analyze the long-run effects across host counties. Through the difference-in-differences (DID) approach by adopting the propensity score matching (PSM), the results show that with the promotion of PV projects, although the total income of rural residents has somewhat rose, growing income inequality coincides with the significant differences in benefits among groups. For poverty-stricken block group the economic beneﬁts are relatively smaller while the negative effects on income equality are less explicit than those for the other groups. Moreover, a substantial increase in income is evident during the periods before the implementation of PV projects. Meanwhile, the growing income gap is long-run and appears only after projects have been carried out. Foreseeably, the promotion of PV projects may be a potential challenge to address relative poverty.","PeriodicalId":158283,"journal":{"name":"ChemRN: Solar & Solar Thermal Energy (Topic)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129730383","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}

Mixed halide Tin (Sn)-based alloyed perovskites with optimal band gaps ranging from 1.15 to 3.55 eV are excellent alternatives to Pb-based perovskites. In this work, we find that the addition of bulky phenylethyl ammonium (PEA) cation in the precursor solution leads to improved solar cell performance and optoelectronic properties. A prolonged laser exposure is found to induce a redshift the sample absorption for the control and no shift for the PEA-added sample, as shown by transient absorption spectroscopy. Further, we show that the addition of PEA improves band alignment of the perovskite with phenyl-C61-butyric acid methyl ester (PCBM), which aids in electron injection and therefore increases photocurrents in solar cells. These results show that PEA addition suppresses halide segregation improving material stability, charge collection at perovskite/electron transport layer, and recombination dynamics in perovskite material. As a result, the PEA-containing Sn-rich PSCs exhibited a champion efficiency of 13% with a high open-circuit voltage of 0.77 V and improved current-voltage hysteretic behavior. These results shed light on the importance of halide segregation and band alignment when designing lead-free PSCs.","PeriodicalId":158283,"journal":{"name":"ChemRN: Solar & Solar Thermal Energy (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133462679","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}
