Polymer solar cells are a new generation of technology (Direct Energy Conversion). Today, the use of sunlight as a rich and accessible source of clean energy has been seriously considered by the international community for many years, and in the meantime, what can be done about the efficiency of this huge energy force. Note that there are significant advances being made by scientists. Solar energy, which generates electricity directly from light, is a good source of energy. In addition, solar energy is one of the cleanest sources of energy available, which can be used to replace fossil fuels. Also, statistical studies of global markets show that the demand for and use of pleasant cells has been increasing rapidly in recent years.
There are different types of solar cells, and the topic we will discuss here will be the polymer solar cell. Polymer solar cells The salient features of solar cells are: low cost, light weight and easy construction. But what adds to their importance is the solubility of the materials used in organic solvents, which makes the production of solar cells flexible.
• Silicon solar cells are fragile, have high production costs
• The most important and most practical material used as an electrode in a polymer solar cell is indium tin oxide. This material is fragile, the cost of production and productivity is very high.
• Fossil fuels pollute the environment by producing carbon dioxide, so we have to think about getting energy from other sources.
Among the different types of solar cells, organic solar cells have attracted a lot of attention due to their advantages such as flexibility, cheapness and.. One of the most important components of organic solar cells is its donor and receiver. (MEH-PPV) and from the receptor material to fullerene derivatives. Among the different connection methods in solar cells, the Bulk Heterojunction method is the best because it increases the contact and donor surface and facilitates electron transfer. Recent efforts have been made to produce electron receivers that have high electron mobility and can be used in place of expensive fullerene derivatives.
