Nanowire arrays could improve solar cells

By -

Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also need to be able to let light in (for solar cells) or out (for displays).
Metal is opaque, so the current techniques use metal oxides, most often indium tin oxide—a near-critical rare earth metal—as the conductive contact. Because supplies of this rare earth metal are limited, Lawrence Livermore National Laboratory (LLNL) researchers have turned to ordered metal nanowire meshes that provide high transmissivity (due to the small diameters of the nanowires), high electrical connectivity (due to the many contact points in the mesh) and use more common elements. The research appears in the journal Soft Matter.

How to create jarvis system / own A.I. assistance Have you want computer like Jarvis. So, your computer will respond to your voice by speaking to you like a human being. Here is procedure how to make   AI System your own just by RAW coding and some tools. Step 1: You have to remove all thing (i.e. all the icons and files) from desktop and set the taskbar to auto hide mode. Follow this: on mouse Right click> view> show desktop icon Step 2: Now download rain meter from given link below: http://rainmeter.net/ After installing rain meter you will see some gadgets on the screen. Step 3: You can move these gadgets just by left-clicking and can do some operations just by a right click. Step 4: Now download these 2 themes from given links: 1.IRON man: http://scrollsofaryavart.deviantart.com/art/IronMan-Jarvis-Theme-Version-2-271590499 2.Avengers: http://chinni1991.deviantart.com/art/Elegant-Theme-1-1-387048490 After downloading these themes install the th...

Stack data structure

Stack Data Structure (Introduction and Program) Stack is a linear data structure which follows a particular order in which the operations are performed. The order may be LIFO(Last In First Out) or FILO(First In Last Out). Mainly the following three basic operations are performed in the stack: Push:  Adds an item in the stack. If the stack is full, then it is said to be an Overflow condition. Pop:  Removes an item from the stack. The items are popped in the reversed order in which they are pushed. If the stack is empty, then it is said to be an Underflow condition. Peek or Top:  Returns top element of stack. isEmpty:  Returns true if stack is empty, else false. How to understand a stack practically? There are many real-life examples of a stack. Consider the simple example of plates stacked over one another in a canteen. The plate which is at the top is the first one to be removed, i.e. the plate which has been placed at the bottommost positio...
