Our approach and results demonstrate that: (1) the detailed study on photodetector characteristics allows the photodiode using the elastomeric bulk heterojunction on a rigid substrate to yield a noise equivalent power 39 pW at 653 nm. (2) With pre-strained PEDOT:PSS\/PDMS as bottom electrode and substrate, the fully stretchable organic photodiode achieves noise equivalent power values in the tens of pico-watt range and an estimated average specific detectivity value of 2.3 \u0026times; 1010 Jones at 653 nm up to at least 60% strain (stretchable up to possibly 100%). (3) The freestanding film of elastomeric bulk heterojunction sustains up to 189% of tensile strain and yields Young\u0026rsquo;s modulus of tens of MPa, which is comparable to human skin. These results provide a proof-of-principle that stretchable organic photodiodes can combine the unique mechanical properties of elastomers while maintaining the remarkable performance of rigid photodetectors.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Low-noise Stretchable Organic Photodiode using an Elastomeric Bulk Heterojunction "}],"uid":"28475","created_gmt":"2021-11-22 21:56:50","changed_gmt":"2021-11-22 21:56:50","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-12-10T09:00:00-05:00","event_time_end":"2021-12-10T11:00:00-05:00","event_time_end_last":"2021-12-10T11:00:00-05:00","gmt_time_start":"2021-12-10 14:00:00","gmt_time_end":"2021-12-10 16:00:00","gmt_time_end_last":"2021-12-10 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
