Redefining the Operation and Design Considerations of Organic Solar Cells: Role of Morphology and Defect States
… organic semiconductors for its absorbing layer. Even though such complex morphology reduces charge loss by separating electrons and holes in respective channels, it introduces many technological problems such as reliability, variability and yield which may preclude the large scale adoption …

Influence of Solvent Additives on Stability, Performance and Morphology of Conjugated Polymer/Fullerene Based Organic Bulk Heterojunction Solar Cells
… additive, on the stability, performance and morphology of conjugated polymer (P3HT)/fullerene (PCBM) based solar cells was studied. In organic bulk heterojunction solar cells the majority of light is absorbed in the donor material. The incident photons are converted to excitons which get …

Characteristics of a New Copolymer For Bulk Heterojunction Solar Cells
<p>Organic solar cells have attractive aspects like flexibility, light-weight, environment-friendliness and low-cost due to manufacturing-ease on large area substrates using roll-to-roll processing, solution casting or screen printing. Most high performance organic solar cells utilize tandem …

Enhanced Charge Transport and Cell Performance of an Inverted Organic Solar Cell Via UV-ozone Treatment of ZnO
… was achieved by treating electron transport layer consisting of ZnO-PVP with UV-ozone. The effect of UV-ozone treatment on ZnO was also studied but in a P3HT:ZnO hybrid solar cell system, where the role of ZnO was as an acceptor rather than an electron transport layer. There are no reports of …

Design and Characterization of Electrospun Mats with Tailored Morphologies for Enhanced Active Layer Performance in Energy Conversion and Energy Storage Applications
… by the electrospinning process to improve the active layer performance in energy conversion devices as well as to better understand the relationship between morphology and performance in energy storage devices. Discrete control of the active layer morphology can promote exciton dissociation in …

Ανάπτυξη υβριδικών υλικών που βασίζονται σε ημιαγώγιμα πολυμερή και νανοδομές άνθρακα
Οι συνεχώς αυξημένες ενεργειακές απαιτήσεις της κοινωνίας έχουν οδηγήσει στη χρήση ανανεώσιμων πηγών ενέργειας. Μεγάλη προσοχή έχει προσελκύσει η μετατροπή της ηλιακής ακτινοβολίας σε ηλεκτρική ενέργεια μέσω των φωτοβολταϊκών διατάξεων. Πολλές και διαφορετικές φωτοβολταϊκές τεχνολογίες έχουν …
