For highly efficient solar cell, absorption of input light should be maximum at all angles. Different surface texturing techniques like pyramid texturing, cone texturing, pillar texturing have been used to increase absorption of light in solar cell. Micro-hole Surface texturing is getting popular in absorption of solar radiation at higher zenith angle. In this paper, effect of varying zenith angle on hole textured solar cell's performance is studied. By varying zenith angle, input solar spectrum irradiance is changed which results in a change in the performance of solar cell. It has been observed that by increasing zenith angle, efficiency of solar cell decreases due to decrease in input spectrum irradiance and less absorption of light from surface. Paper also presents a comparison of plane surface solar cell and the hole textured solar cell. Hole textured solar cell shows better performance than the plane surface solar cell at normal angle of incidence. The difference in the performance of both types of solar cell becomes more pronounced with the increase in the zenith angle.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133190608","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}

Then, OI (Optimal interpolation) algorithm is used to obtain data assimilation results for each grid.

Considering the current situation of lacking time-varying data of intermittent energy source, this paper studies the output fluctuation of intermittent energy source in Northwest China based on the data from the National Aeronautics and Space Administration (NASA) Goddard Earth Sciences Data and Information Services Center (GES DISC). The paper firstly extracts wind speed and surface net downward shortwave flux of 10 years as initial data and converts the data into generation output using specific device parameters. Then a statistical analysis is made about the regional, annual, seasonal, and day-night output of the wind and photovoltaic power. It has calculated the best capacity configuration by combining wind and solar energy to describe the complementary degree. The results suggest that annual difference between wind and PV power output is slight, while the regional, seasonal, and day-night differences are obvious, and the outputs of wind and PV are complementary. These results provide the basis to determine reserve capacity considering grid integration of renewable energy generation. These data provide decision support for the construction of wind and photovoltaic farms.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130002557","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}
