LID free crystalline silicon modules

Light induced degradation (LID) has been a characteristic of most commercial monocrystalline photovoltaic modules. Shell Solar Industries has developed an LID-free module design deploying improvements in both cell and module stability. The cell improvements have come about by a substitution of doping materials in crystal growth. This eliminates approximately one half of the LID performance drop. The module improvements have been developed using stable cover glass coupled with an improved EVA layer, which exhibits good stability and production compatibility. Together these changes represent an increase in performance of nearly 4%, which is substantial on modules, which exceed 170 Wp. The improvements in processing have an added economic benefit, as they are virtually one to one substitutions in the manufacturing process with no additional costs. Shell Solar Industries is currently certifying these changes to cell and module design to deploy these changes in the standard product line.
