Low carbon development has become the theme of today’s social development, which foundation was renewable energy.For example: photovoltaic power generation, wind power generation, hydropower generation and so on.One of the representatives of new energy is photovoltaic power generation. After a long period of development, photovoltaic power generation technology has become more and more mature. For improved solar cell stability, photoelectric conversion efficiency, low cost and data security of energy information. 3D printing system and method of organic polymer solar cell device based on blockchain was rough design. 3D printing technology could be used to replace traditional manufacturing technology to complete the printing and manufacturing of solar cell devices. In order to meet the requirements. First, Modeling solar cell structure according to customer requirements, and then process simulation and performance analysis, 3D printing manufacturing after reaching the standards.For data security combining blockchain technology with 3D printing technology, the data security problem of 3D printing could be solved. Blockchain technology has been use to data structure to verify and store data. Blockchain could be considered as a distributed ledger which was decentralized, non-tamperable, traceable, and maintained by multiple parties. By applying the features of blockchain technology such as data encryption, time stamping, and distributed consensus to 3D printing technology, combined with the cloud platform, the cost and stability of 3D printed solar cell devices would be further improved.
