Detailed explanation of the working principle, advantages and disadvantages of organic solar cells


Organic solar cells are solar cells made from organic materials such as dyes or conjugated polymers, Able to convert sunlight into electrical energy, It has high stability and preparation flexibility.

有机太阳能电池(Organic-Solar-Cell,OSC)

The working principle of organic solar cells is, After absorbing sunlight, Photons excite and separate charges, Charge carriers are formed. In organic solar cells, Conjugated polymers are usually used as charge transport materials, where cations or oxides with low ionization potential act as electron acceptors, The charge transfer between the conjugate group and the electron acceptor constitutes the process of charge separation and transport, This is a determining factor in the performance of organic solar cells.

Compared with traditional silicon solar cells, organic solar cells have the characteristics of low preparation cost, good flexibility and adjustable color, Specifically, Its main advantages are:


  1. Low preparation cost: Compared to silicon solar cells, Organic solar cells are cheaper to manufacture, and the preparation process is simple, Simple preparation methods such as printing can be used.


制备成本低


2.Good flexibility: Since organic solar cells use flexible organic substances and substrates, Therefore it has higher bending and thinness, Flexible solar cells can be made into various forms.


柔性性好


3.Color adjustable: Organic solar cells are manufactured using organic materials such as dyes or conjugated polymers, to by replacing the types and proportions of materials, Enable tunability of solar cell color range.


颜色可调


Organic solar cells also have some disadvantages, mainly include:


1.low efficiency: Current conversion efficiencies of organic solar cells are lower than those of crystalline silicon solar cells.


效率低


2.Poor stability: Organic matter itself is relatively susceptible to factors such as light, oxygen, moisture, etc. Therefore, organic solar cells have poor stability, Hardly suitable for long-term stable operation requirements.


稳定性差


3.Short life: Due to the relatively short life of organic solar cell materials, Stable output of solar cells over a long period of time cannot be guaranteed.


寿命短


At present, Organic solar cell technology is still under continuous research and development, Its advantages in flexibility, low cost, and adjustable color still have great prospects and potential.


目前,有机太阳能电池技术仍在不断的研发中,其在柔性、低成本、颜色可调等方面的优势还是具有非常大的前景和潜力。
