Nowadays Si-based solar cell (SC) remains the main source of solar energy in the world due to low cost of material and relatively simple, industrially acceptable technology. Despite of significant progress on increasing efficiency of these devices (the best laboratory samples demonstrated efficiency as much as 43.5%), for most of industrially manufactured SC’s the efficiency remains in the range of 10–18% [1]. A promising way to minimize thermodynamic losses for high efficiency Si-based photovoltaic devices, is photonic design of the device surfaces. The last one causes light trapping into the device, due to light interaction with micro- nano-structured surfaces, thus increasing effective light path interaction. However, the most of proposed methods for Si surface modification do not match industrial production requirements: such as fast manufacturing, environmental issues, and low cost per watt for final devices.

Analytical Modelling, Simulation and Comparative Study of Multi-Junction Solar Cells Efficiency Hadjdida, Abdelkader; Bourahla, Mohamed; Ertan, Hulusi Bülent; Bekhti, Mohamed (2018-12-01) Currently, solar energy is promising the primary source of renewable energy that has a great potential to generate power for an extremely low operating cost when compared to already existing power generation technologies. Increasing the efficiency of solar cells is a major goal and the prominent factor in photovoltaic system research. Current triple junction solar cells reach 30% and the next generation will bring 35% in 5 years to peak at 40%. These cells are used in space environment and in terrestrial sy...
Fabrication and characterization of single crystalline silicon solar cells Es, Fırat; Turan, Raşit; Department of Physics (2010) The electricity generation using photovoltaic (PV) solar cells is the most viable and promising alternative to the fossil-fuel based technologies which are threatening world’s climate. PV cells directly convert solar energy into electrical power through an absorption process that takes place in a solid state device which is commonly fabricated using semiconductors. These devices can be employed for many years with almost no degradation and maintenance. PV technologies have been diversified in different dire...
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...
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...
