Abstract Organic photovoltaics (OPV) now can exceed 20% power conversion efficiency in single junction solar cells. To close the remaining gap to competing technologies, both fill factor and open‐circuit voltage must be optimized. The Langevin reduction is a well‐known concept that measures degree which charge extraction favored over recombination. It therefore ideally suited as an optimization target high‐throughput workflows; however, its evaluation so far requires expert interaction....
While the power conversion efficiency (PCE) of organic photovoltaics (OPV) on small‐area lab cells has rapidly increased during last few years, performance module level and availability OPV modules market is still limited, primarily due to specific constraints imposed by industrial production process. This work deals with upscaling process latest‐generation from fully solution‐processed modules, which are compatible roll‐to‐roll (R2R) printing. transfer demonstrated step material selection...
Unencapsulated organic solar cells are prone to severe performance losses in the presence of moisture. Accelerated damp heat (85 °C/85% RH) studies presented and it is shown that hygroscopic hole‐transporting PEDOT:PSS layer origin device failure case prototypical inverted cells. Complementary measurements unveil under these conditions a decreased work function along with areas reduced electrical contact between active hole‐transport main factors for degradation rather than chemical reaction...
As part of an unprecedented collaborative outreach effort, we implemented innovative STEM project, where more than 80 middle and high school students from different traditionally underrepresented districts in Colombia -with no previous knowledge on material science or photovoltaics- created Last Generation Solar Cells (LGSCs) that were several suborbital spaceflight missions. a result, the able to contrast visual instrumental data obtained solar cells modules launched space with similar...
