Substitution of highly doped layers with conventional transparent conductive electrodes as carrier collecting and selective contacts in conventional crystalline silicon (c-Si) solar cell configurations is crucial in increasing affordability of solar cells by lowering material costs. In this study, oxide/metal/oxide (OMO) multilayers featuring molybdenum oxide (MoOx) and silver (Ag) thin films are developed by thermal evaporation technique, as dopant-free hole transport transparent conductive electrodes (HTTCEs) for n-type c-Si solar cells. Semidopant-free asymmetric heterocontact (semi-DASH) solar cells on n-type c-Si utilizing OMO multilayers are fabricated. The effect of outer MoOx layer thickness and Ag deposition rate on the photovoltaic characteristics of the fabricated semi-DASH solar cells are investigated. A comparison of front side pyramid textured and flat surface solar cells is performed to optimize the optical and electrical properties. Highest efficiency of 9.3% +/- 0.2% is achieved in a pyramid textured semi-DASH c-Si solar cell with 15/10/30 nm of HTTCE structure.

Numerical analysis ofdopant-freeasymmetric silicon heterostructure solar cell withSiO(2)as passivation layer 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...
PEM fuel cell degradation effects on the performance of a stand-alone solar energy system ÖZDEN, Ender; Tarı, İlker (Elsevier BV, 2017-05-04) After comparing fresh and degraded performances of Polymer Electrolyte Membrane (PEM) based components of a hydrogen cycle with the help of computational fluid dynamics simulations, recently established stand-alone solar energy system producing hydrogen for energy storage is investigated focusing on the effects of degradation of fuel cells on the overall performance of the system. A complete model of the system has been developed using TRNSYS, and a degraded PEM Fuel Cell Subsystem has been incorporated int...
Concentrated Solar Power Harvesting Using Self-powered, Wireless, Thin-profile, Lightweight Solar Tiles Ardanuc, Serhan M.; Lal, Amit; Jones, Samuel C. (ASME International, 2011-08-01) This paper presents a modular and scalable approach to concentrated solar power (CSP) harvesting by using low-profile, light-weight, sun-tracking, millimeter-to-centimeter-scale mirror arrays that can be wirelessly controlled to reflect the incident solar energy to a central receiver. Conventional, utility-scale CSP plants use large-area heliostats, parabolic troughs, or dish collectors that are not only heavy and bulky, but also require significant labor for installation and maintenance infrastructure. Fur...
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...
Statistical analysis of solar radiation data Yilmaz, E.; Cancino, B.; Parra, W. R. (Informa UK Limited, 2007-01-01) Solar radiation is the most important parameter in the design and study of solar energy conversion devices. The present work is based on statistical analysis of solar radiation data for the city of Valparaiso in the coast region of Chile. Experimental data were obtained from the Santa Maria University in Valparaiso over a five-year period measured by the actinograph and the pyranometer. The error between the actinography values in relation to the pyranometer ones was determined. The most frequent error perc...
