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 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.

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...

In the development of high efficiency crystalline Si solar cells, decreasing bulk and surface recombination velocities of the minority carriers is vital. As the bulk recombination could be suppressed by enhancing the material quality, the effect of surface recombination on cell performance becomes more dominant. Also, recent studies have revealed that the area under the metal contacted region needs to be passivated to minimize the carrier recombination. The passivation of front and back surface of the cell ...
Optimizing the orientation of solar photovoltaic systems considering the effects of irradiation and cell temperature models with dust accumulation
Al-Ghussain, Loiy; Taylan, Onur; Abujubbeh, Mohammad; Hassan, Muhammed A. (2023-01-01)
© 2022To cope with the growing installation capacities of solar photovoltaic (PV) systems in desert areas, it is necessary to revisit the energy production models and the optimal angles of PV panels given the significant impacts of ambient temperature, wind speed, dust accumulation, and cleaning frequency. In this study, these four factors are examined for four PV technologies (polycrystalline, microcrystalline, monocrystalline, and thin-film) at three cities in Jordan, Egypt, and Tunisia using precise grou...

P-type solar cells currently hold most of the market share in industrial solar cell fabrication statistics. NREL's highest efficiency record for p-type crystalline perc cells is 22.8%. However, there is an ever-increasing interest in n-type wafers due to the many advantages they have against p-type cells. According to the ITRPV's estimation, the n-type cell structures will be taking half the industry's share by 2031. Compared to p-type cells, n-type cells yield better efficiency and lifetime values and are ...

Reflection and transmission through a solar cell can be significantly reduced using light-trapping structures. This approach can be applied to both crystalline and thin-film solar cells to improve the light absorption and conversion efficiency of the cell. In this study, vertically aligned Si nanowires were fabricated over a large area via a metal-assisted etching technique. Following a detailed parametric study, nanowires were applied to industrial-size (156 mm x 156 mm) Si solar cells. The reflectivity fr...
