In　order　to　widely　realize　the　personalized　use　of　solar　thin-film　cells　in　every　family,　save　costs　and　generate　clean　energy,　our　team　wants　to　fabricate　a　3D　printer　of　solar　thin-film　cells.　The　solar　film　cells　were　3D　printed　fabrication　by　FDM3D　printer　would　improve　their　performance　as　battery.　In　this　paper,　for　fabricate　P　nano-diamond/ZnO　solar　film　cells　the　hot　bed　and　nozzle　of　3D　printer　were　designed　to　achieve　3D　printing　of　solar　cells.　A　printer　for　fabricated　solar　thin-film　cells　was　designed.　PID　was　used　to　set　the　temperature　of　printer　nozzle,　and　a　refrigeration　device　was　added　to　the　substrate.　And　then　finally,　the　printing　device　was　simulated　by　SW.　©　Published　under　licence　by　IOP　Publishing　Ltd.
