"transparent electrode—made of indium tin oxide... roll-to-roll (R2R) vacuum coating... ITO... same sheet resistance pristine film substrates... R2R slot-die coating... OPV cells... encapsulation printing organic...  OPV layers on PP substrate 50% rPP recovered from drink pouch... max efficiency 1%... single-use smart packaging productions with sufficient electrical power... achievable to increase the efficiency of OPV cells printed on recyclable material, which is made with 50% rPP, by more than 5%"
