The Introduction of DSSC

A solar cell is a typical energy source that converts light energy into electric energy by using an unlimited clean energy source, sunlight. The solar cell does not need the supply of additional fuel, but a solar photovoltaics. Another attractive feature is that it does not cause secondary environmental pollution.
Relatively high price in comparison to the technology was the main obstacle for wide use of solar cells, however as of recently this challenge is being overcome by subsidies granted from ations' governments and market expansion.
Moreover, dye-sensitized solar cells, organic semiconductors using materials of the organic world, as well as existing emiconductor-based inorganic solar cell technologies are coming into the spotlight.

The next generation sunlight batteries which are being developed by Samsung SDI are dye-sensitized solar cells, also known as DSSC. In comparison to existing silicon semi-conductive solar cells, they are cheaper, more transparent, and able to realizevarious colored solar cells.
Due to this characteristic, DSSC is noticed to be pproper for the building integrated photovoltaic(BIPV) that uses solar cells as outer walls or glass windows of buildings.

What is DSSC

* A dye-sensitized solar cell, DSSC is an electrochemical battery using chemical reactions, and generating electricity when photo-sensitized dye absorbs the sunlight and generates electrons. The principle of power generation of DSSC is very similar to that of photosynthesis of plants, so it is often referred to as artificial photosynthesis. Its materials and processes are cheaper than existing semi-conductive solar cells. It is environment-friendly, transparent due to the characteristic of the materials, and especially able to realize various colored solar cells.
