Abstract
The scalingofthin film photovoltaicstoacommerciallyviablesizereliesontheseriesconnectionof multiple smallcellsintomodules.Theseinterconnectionsaretypicallyformedbythreepatterningsteps, each of whichhaveanimpactontheseriesresistanceandconsequentlyonthetotalmoduleperformance. Here,weimplementthetransmissionlinemethodforthecompleteanalysisoftheP2patterning step ofthephotoactive layer in organic photovoltaic modules. Devices are investigated with a sample design that allows for a comparative study of the P2 connection on the solar cell performance.We compare subtractive mechanical scribing to a newly developed additive pre-patterning method for the P2 step.Aerosol Jet printed pre-patterning lines of low surface energy and conductive poly (3,4ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) modified with a fluorosurfactant repel the subsequently spray coated photoactive layer. Furthermore, the influence of MoO3 in the P2 pattern is elucidated, displaying a substantial increase in series resistance and decrease in device performance.| File | Dimensione | Formato | |
