METHOD FOR PRODUCING PHOTOVOLTAIC MODULES IN A VACUUM LAMINATOR HAVING A REDUCED PROCESS VACUUM

摘要

The invention relates to a method for producing photovoltaic modules comprising a laminated structure composed of a) a transparent front cover, b) one or more photosensitive semiconductor layers, c) at least one plasticized, polyvinyl acetal-based film and d) a rear cover. The method according to the invention is characterized in that a layer structure consisting of layers a) to d) is bonded in a process chamber at a temperature of 120 - 190°C and at a gas pressure of 200 to 5*104 Pa to give a laminated structure.
