This paper is about solar irradiation estimation on a solar powered UAV over its mission course [1]. Solar irradiation estimation and maximizing the solar energy collection are critical for solar powered UAVs and their performance. In this paper main focus is on solar irradiation calculations and comparison of two possible flight paths for solar energy collection during a transport or inspection mission.


Simulation Studies of Hole Textured and Planar Microcrystalline Silicon Solar Cell at Different Zenith Angle
Zainab, Sana; Hussain, Shahzad; Altinoluk, Serra H.; Turan, Raşit (2017-09-23)
Efficiency of solar cell greatly depends on its interaction with input solar irradiance. 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...

Pınar, Erdem Emre; Baker, Derek Keıth; Uzgören, Eray; Department of Mechanical Engineering (2013)
In this thesis, energy optimal route of an unmanned solar powered air vehicle is obtained for the given mission constraints in order to sustain the maximum energy balance. The mission scenario and the constraints of the solar powered UAV are defined. Equations of motion are obtained for the UAV with respect to the chosen structural properties and aerodynamic parameters to achieve the given mission. Energy income and loss equations that state the energy balance, up to the position of the UAV inside the atmos...
Selective emitter formation via single step doping through laser patterned mask oxide layer for monocrystalline silicon solar cells
Çiftpınar, Emine Hande; Turan, Raşit; Department of Physics (2014)
Selective emitter is one of the new approaches for higher efficiency solar cells. Although selective emitter cells could be processed by several different methods such as; etch back process, laser doping, ion implantation, doping paste, a different method based on diffusion through a laser patterned oxide layer was studied in this thesis. Utilization of pattern oxide layer as a diffusion barrier enables to obtain selective emitter profile via single step doping which reduces overall production cost and time...
Estimation of diffuse component for two locations in Turkey
Karaveli, Abdullah Bugrahan; Akınoğlu, Bülent Gültekin (2016-10-14)
In analyzing the solar energy systems, the first step is the accurate measurements/estimations of the input in the long term: solar irradiation incident on the panels. The measurements are lacking in many places so the estimation procedures should be developed using the measured data of the locations having similar climates and close in latitudes. In most life cycle assessments, monthly averages of daily values are utilized in the form of typical meteorological year or simply with the averages of a year or ...
Surface texturing study with aluminum induced texturing method on soda-lime glass substrates for thin film solar cells
Ünal, Mustafa; Turan, Raşit; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2017)
It is essential to employ an effective light trapping scheme to decrease the cost of produced solar electricity further in thin film solar cell technologies. There are several methods that can be used for light trapping and aluminum induced texturing (AIT) is one of them. The aim of this thesis study is to obtain highly effective light trapping interface via texturing of glass surface by AIT process. The resultant texture is affected by several parameters such as Al thickness, annealing time and temperature...
