Nanostructures improve solar cell efficiency

To make solar cells a competitive alternative to other renewable energy sources, researchers are investigating different alternatives. A step in the right direction is through new processes that change the surfaces of silicon solar cells. By creating different nanostructures on the surfaces, the energy harvesting properties of solar cells can be improved.

The Beginning..

Translation Say: "Call upon other (gods) whom ye fancy, besides Allah. They have no power,- not the weight of an atom,- in the heavens or on

earth: No (sort of) share have they therein, nor is any of them a helper to Allah.

(Katakanlah: " Serulah mereka yang kamu anggap (sebagai Tuhan) selain Allah, mereka tidak memiliki (kekuasaan) seberat zarrah pun di langit dan di bumi, dan mereka tidak mempunyai suatu saham pun dalam (penciptaan) langit dan bumi dan sekali-kali tidak ada di antara mereka yang menjadi pembantu bagi-Nya.) (Surah Saba’ 34: ayat 22)

Zarah or atom/particle is a basic unit of matter in which will built-up or combined with each other, in same or different species, to form bigger object or matter with more stable condition to it self or with surrounding. Nowadays, nanomaterials or nanotechnology has been among the emerging or maybe already esta

blished as one of the way in manipulating nature in order to get the most requisite properties of new materials of devices with a vast range of applications.

A nanometer is one-billionth of a meter, which is 10 by the power of minus 9 of a meter. With this size, a lot of properties of the materials give an interesting effect and sometime totally differ form its bulk properties. In electronic, medical and communication field, the idea of reducing the size of respective subject give a very important contribution to the mankind.

This blog will be contributing in collecting or

publishing the latest news or findings in nanotechnology/nanomaterials that are the area that the author is trying to embark right now. Any comment or information regarding to the subject matter in which the reader want to share with is highly appreciate.
