An environment-friendly photovoltaic module manufacturing process and a photovoltaic module are provided. The environment-friendly photovoltaic module manufacturing process includes: preparing a solar cell assembly; fixing a junction box on the solar cell assembly in such a manner that a bus bar of the solar cell assembly is introduced into the junction box; fixing the bus bar to a metal slice in the junction box by welding; injecting a highly thermal conductive silica gel into the junction box; and curing the highly thermal conductive silica gel. The junction temperature of the junction box can be reduced by means of combining the junction box and the highly thermal conductivity silica gel with a high thermal conductivity, so that the junction box can withstand higher temperature, and can be used in the photovoltaic module with large cell size and high current requirements.
