Back contact modules made using a conductive back sheet foil have a number of advantages over standard H pattern modules including a higher power output, compatibility with very thin cells and high throughput, high yield manufacturing. For a conductive back sheet based module the most cost critical components are the conductive back sheet and the conductive adhesives used to make the contact between the cells and the conductive back sheet. In this paper a number of methods for reducing the module materials cost will be presented. Climate chamber testing of low cost foils without isolation coating and without silver contacts demonstrated that this type of foil is reliable in damp heat, reaching 2000 hours at 85%RH and 85°C with a loss in fill factor of less than 2%.
