Nanotechnology will produce low-cost solar cells

Never attempt to know what you bring next discovery. For decades, scientists have been experimenting with a polymer in macroscopic quantities like the plug until recently did not know that it can be used to create cheap photovoltaic elements using the self-assembly of nanomaterials.

Trans-national team of researchers from the U.S., Germany, France and the UK showed how even reduce the cost of photovoltaic cells, while increasing their effectiveness.

Polymer, called gyroid, researchers have known for a long time. Nanotechnology noticed that his porous structure is perfectly suited for creating complex and thus inexpensive photovoltaic cells.

Production principle is simple photocell two polymer layer is formed "sandwich", wherein one of the layers is filled with a conductor, forming thus a basis element, and the other serves as a device substrate. After the heat treatment, and etching both the polymer layer is removed, a porous conductor. It is covered with a photosensitive dye, and only then - conductor "sponge" is filled with a conductor containing an excess of positively charged "holes".

As a result, scientists have obtained a simple solar cell. It should be noted that the mass production of these electronic devices can be significantly reduced due to the use of "gyroid" One of the researchers, Ulrich Weisner (Ulrich Wiesner), says that achieving self-assembly in the first phase of production, you can still reduce the amount of finished photovoltaic cell.
