The system has been successfully proven indoors with an audio signal. The emitter consists of three commercial high-power white LEDs connected in parallel. The receiver is based on an organic photodetector having as active layer a blend of poly(3-hexylthiophene) (P3HT) and phenyl C61-butyric acid methyl ester (PCBM). The OPD is opto-electrically characterized, showing a responsivity of 0.18 A\/W and a modulation response of 790 kHz at \u22126 V.<\/jats:p>","DOI":"10.3390\/s130912266","type":"journal-article","created":{"date-parts":[[2013,9,12]],"date-time":"2013-09-12T12:13:05Z","timestamp":1378987985000},"page":"12266-12276","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":67,"title":["Visible Light Communication System Using an Organic Bulk Heterojunction Photodetector"],"prefix":"10.3390","volume":"13","author":[{"given":"Bel\u00e9n","family":"Arredondo","sequence":"first","affiliation":[{"name":"Electronic Technology Department, University Rey Juan Carlos, Calle Tulip\u00e1n s\/n,  M\u00f3stoles 28933, Madrid, Spain"}]},{"given":"Beatriz","family":"Romero","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Rey Juan Carlos, Calle Tulip\u00e1n s\/n,  M\u00f3stoles 28933, Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5903-5967","authenticated-orcid":false,"given":"Jos\u00e9","family":"Pena","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Carlos III de Madrid, Avda. de la Universidad,  30, Legan\u00e9s 28911, Madrid, Spain"}]},{"given":"Agust\u00edn","family":"Fern\u00e1ndez-Pacheco","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Carlos III de Madrid, Avda. de la Universidad,  30, Legan\u00e9s 28911, Madrid, Spain"}]},{"given":"Eduardo","family":"Alonso","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Carlos III de Madrid, Avda. de la Universidad,  30, Legan\u00e9s 28911, Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2304-129X","authenticated-orcid":false,"given":"Ricardo","family":"Vergaz","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Carlos III de Madrid, Avda. de la Universidad,  30, Legan\u00e9s 28911, Madrid, Spain"}]},{"given":"Cristina","family":"De Dios","sequence":"additional","affiliation":[{"name":"Electronic Technology Department, University Carlos III de Madrid, Avda. de la Universidad,  30, Legan\u00e9s 28911, Madrid, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2013,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"578","DOI":"10.1039\/c39770000578","article-title":"Synthesis of electrically conducting organic polymers-halogen derivatives of polyacetylene (CH)","volume":"16","author":"Shirakawa","year":"1977","journal-title":"J.
