Oval = canvas.create_polygon(x0, y0, x1, y1.xn, yn, options)Ĭ = Tkinter.Canvas(top, bg="blue", height=250, width=300)Īrc = C. Figure 7: Different reactions occuring in the furnace arc. Polygon − Creates a polygon item that must have at least three vertices. In the case of device optimization, the SiO2 passivation layer with a refractive index of 1.48 and the Si3N4 ARC layer with a refractive index of 2.015 has been identified as the best combination. Oval = canvas.create_oval(x0, y0, x1, y1, options) It takes two pairs of coordinates the top left and bottom right corners of the bounding rectangle for the oval. The results confirmed that the Al 2 O 3 single ARC layer with a thickness of 83 nm resulted in the best efficiency of 17.81, in comparison with other AR materials such as MgF 2, SnO 2. Oval − Creates a circle or an ellipse at the given coordinates. The impact of using different materials for the single ARC layer on the overall performance of the solar cell was investigated using PC1D simulation software. These cells had no ARC/surface passivation. Line = canvas.create_line(x0, y0, x1, y1. The highest efficiency cell achieved was 7.26 out of a theoretical 8.73. Image = canvas.create_image(50, 50, anchor=NE, image=filename) Image − Creates an image item, which can be an instance of either the BitmapImage or the PhotoImage classes.įilename = PhotoImage(file = "sunshine.gif") The Canvas widget can support the following standard items −Īrc − Creates an arc item, which can be a chord, a pieslice or a simple arc.Īrc = canvas.create_arc(coord, start=0, extent=150, fill="blue") If the canvas is scrollable, this attribute should be the. Works like xscrollincrement, but governs vertical movement. set() method of the horizontal scrollbar. If you set this option to some positive dimension, the canvas can be positioned only on multiples of that distance, and the value will be used for scrolling by scrolling units, such as when the user clicks on the arrows at the ends of a scrollbar. Some of the values are SUNKEN, RAISED, GROOVE, and RIDGE.Ī tuple (w, n, e, s) that defines over how large an area the canvas can be scrolled, where w is the left side, n the top, e the right side, and s the bottom. If true (the default), the canvas cannot be scrolled outside of the scrollregion.Ĭursor used in the canvas like arrow, circle, dot etc. These options can be used as key-value pairs separated by commas. Options − Here is the list of most commonly used options for this widget. the excitation light source, PC1D can calculate both current-voltage characteristics and spectral quantum efficiency of the solar cell, but it also has a large number of other options for output data, both in the spatial domain and in the time domain. Master − This represents the parent window. To use them the user just taps their three fingers on the top of the Arc Mouse. Here is the simple syntax to create this widget − Those are important options for users and is something the older Microsoft Arc Touch Mouse SE cannot do. You can place graphics, text, widgets or frames on a Canvas. The Canvas is a rectangular area intended for drawing pictures or other complex layouts.
