Organic Solar Cell (OSC) is a solar cell made of organic materials such as dyes or conjugated polymers, which can convert sunlight into electrical energy, and has high stability and preparation flexibility.
 
Organic solar cells work by absorbing sunlight and photons excite and separate charges to form charge carriers. In organic solar cells, conjugated polymers are usually used as charge transport materials, in which cations or oxides with low ionization potential are used as electron acceptors, and the charge transfer between the conjugated group and the electron acceptor constitutes the charge separation, the process of transport, which is the determinant of the performance of organic solar cells.
 
Compared with traditional silicon solar cells, organic solar cells have the characteristics of low manufacturing cost, good flexibility, and adjustable color. Specifically, their main advantages are:
 
Low manufacturing cost: Compared with silicon solar cells, the manufacturing cost of organic solar cells is lower, and the preparation process is simple, and simple preparation methods such as printing can be used.
 
Good flexibility: Since organic solar cells use flexible organic substances and substrates, they have higher bendability and thinness, and can be made into various forms of flexible solar cells.
 
Adjustable color: organic solar cells are made of organic materials such as dyes or conjugated polymers, and the color range of solar cells can be adjusted by changing the type and ratio of materials.
 
Organic solar cells also have some disadvantages, mainly including:
 
Low Efficiency: Current organic solar cells have lower conversion efficiencies than crystalline silicon solar cells.
 
Poor stability: Organic substances are more easily affected by factors such as light, oxygen, and moisture. Therefore, organic solar cells have poor stability and are hardly suitable for long-term stable operation.
 
Short lifespan: Due to the relatively short lifespan of organic solar cell materials, the stable output of solar cells cannot be guaranteed for a long time.
 
At present, organic solar cell technology is still under continuous research and development, and its advantages in flexibility, low cost, and adjustable color still have great prospects and potential.
