Bifacial solar modules can use the solar irradiation reaching directly to its back surface as their cells are constructed to have photovoltaic response for both faces. They have been investigating since 1960s and hold a promising future compared to mono-facial cells. Since bifacial solar modules capture photons from both surfaces, the efficiency of a bifacial solar module strongly depends on the rear side illumination. This thesis aims to construct a model to calculate the rear side solar irradiation incident on a bifacial module. We also examine the variation of solar irradiation at different heights of the rear surface and effect of shading. The thesis also aims to outline a model procedure to reach the yield of a bifacial module. The modelling is verified using experimental data measured in GÜNAM’s Outdoor Test Facility.

Mehmood, Haris; Nasser, Hisham; Tauqeer, Tauseef; Turan, Raşit (Wiley, 2020-08-01)
Conventional silicon heterojunction solar cells employ defects-prone a-Si:H layers for junction formation and passivation purposes. Substituting these layers with hole-selective MoO(x)and electron-selective TiO(x)can reduce parasitic absorption and energy band offsets issues associated with doped silicon films. In this work, dopant-free asymmetric heterostructure Si solar cells are studied with and without SiO(2)passivation layer, and their performance has been compared. The inclusion of ultrathin SiO(2)ins...
Evaluation of hybridsolar-wind-hydrogenenergy system based on methanol electrolyzer
Budak, Yagmur; DEVRİM, YILSER (Wiley, 2020-10-01)
In this study, it is aimed to meet the annual electricity and heating needs of a house without interruption with the photovoltaic panel, wind turbine, methanol electrolyzer, and high temperature proton exchange membrane fuel cell system. The system results show that the use of the 2 WT with 18 PV was enough to provide the need of the methanol electrolyzer, which provides requirements of the high temperature proton exchange membrane fuel cell. The produced heat by the fuel cell was used to meet the heat requ...
Simulations of a large scale solar thermal power plant in Turkey using concentrating parabolic trough collectors
Usta, Yasemin; Baker, Derek Keıth; Kaftanoğlu, Bilgin; Department of Mechanical Engineering (2010)
In this study, the theoretical performance of a concentrating solar thermal electric system (CSTES) using a field of parabolic trough collectors (PTC) is investigated. The commercial software TRNSYS and the Solar Thermal Electric Components (STEC) library are used to model the overall system design and for simulations. The model was constructed using data from the literature for an existing 30-MW solar electric generating system (SEGS VI) using PTC’s in Kramer Junction, California. The CSTES consists of a P...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator
BAĞMANCI, MEHMET; KARAASLAN, MUHARREM; ÜNAL, EMİN; AKGÖL, OĞUZHAN; Sabah, Cumali (2017-07-01)
A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. Owing to this combination, the structure exhibits plasmonic resonance characteristics. In the entire spectrum of visible frequency region, the obtained results show that investigated structure has perfect absorptivity which is above 91.8%. Proposed structure also has 99.87% absorption...
