The main limitation of these solar cells up to now has been their low open-circuit voltage (Voc), which is typically below 0.55 V even for high illumination levels. Recently, we have presented a p-n Mos2 homojunction that exhibits a Voc of 1.02 V under broadband illumination equivalent to 40 suns. The use of substitutionally-doped $p$ and $n$ Mos2 material instead of a heterojunction is crucial to produce a band alignment that enables high Voc. Another important aspect for the realization of large photovoltages in TMDC solar cells is the optimization of metallic contacts. We demonstrate using a simple circuital model that the presence of Schottky barriers at the semiconductor/metal interfaces does not only introduce a non-ohmic series resistance, but also reduces the Voc because the Schottky diodes are photoactive. We characterize the Schottky barrier produced by different metals in combination with $p$ and $n$ Mos2. When p-flakes are deposited directly onto a SiO2/Si substrate, we find that they are depleted from carriers by a surface doping effect. This depletion contributes to aggravate the effect of the p-MoS2/metal Schottky. We show that inserting a flake of hexagonal boron nitride (h-BN) between the p-material and the SiO2 surface eliminates this effect. Given the already demonstrated strong light absorption of TMDC ultra-thin devices, the achievement of high Voc is a turning point in the path towards high-efficiency TMDC solar cells.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72977577","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}

It has been repeatedly shown that organizations and companies are more productive when they have diverse and inclusive cultures. The solar industry in the U.S. performs well in some aspects (non-white workforce, positive work environment) but drastically under-performs in many others. We discuss these metrics and how this impacts the renewable energy industry and the solar research community. We highlight some initial actions which are necessary to begin to remediate these deficiencies, such as demographic tracking, recruiting strategies, and mentoring. We also present the historical and ongoing efforts to improve the diversity and inclusion of the Photovoltaic Specialists Conference, particularly through the work of this year's Diversity and Inclusion (D&I) oversight committee. This year's D&I committee is implementing diversity tracking, a women's lunch, a diversity lunch, childcare resources, pronouns on badges, gender-neutral restrooms, addressing accessibility issues, and publishing a diversity statement and code of conduct to the PVSC website.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75585291","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}

Therefore, the use of photovoltaics (PV) is a viable, clean energy source for the GCC region. This paper presents a detailed techno-economic study for the implementation of a grid-connected rooftop photovoltaic and energy storage system (PV-ESS) in the State of Qatar. This study aims to present a detailed cost analysis as well as sizing information for a house in Qatar. A multi-objective optimization that considers generation and load profiles, cost of grid consumption, cost of materials, and house size is presented in the form of Pareto frontier curves. Load modulation is introduced as a method to lower capital expenditure and operational costs. The benefit to a developed country like Qatar is to improve the resilience of the electrical supply and reduce the carbon footprint. The benefit to a developing country is that it brings electricity to individual homes without needing an expensive utility grid. Although this paper is not intended to study energy policy, the techniques presented can be used to recommend energy policies. The results of this study are presented in the form of implementation steps to make rooftop PV-ESS systems feasible in Qatar based on factual information and detailed analysis.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74569369","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}
