Inverse perovskite solar cell stability using MoS2
The present thesis studies the fabrication and stability of organic-inorganic CH3NH3PbI3 solar cells. Due to their high reported efficiency and easy processability, photo-voltaics are being reinvented with perovskite technology. PVK's are fast producing, low cost, rapidly increasing efficiency...

Por las altas eficiencias reportadas y la facilidad de fabricación las celdas solares con esta tecnología están reinventando el campo de los fotovoltaicos. Estas celdas solares son una tecnología rápida de producir; que pose bajo costo de producción; y tienen un alto crecimiento en su eficiencia. El desarrollo de la estabilidad en esta tecnología podría hacer de los fotovoltaicos una alternativa viable para suplir la demanda energética. Para proteger la perovskita de la humedad y la migración de iones provenientes del electrodo metálico en celdas con arquitectura inversa, se usa una capa de MoS2 sobre la capa transportadora de electrones (PCBM). Este método logro conservar las corrientes de corto circuito y ayudo a mantener la forma en la curva I-V, las celdas sin esta capa perdían rápidamente sus propiedades.FísicoPregrado56 hojasapplication/pdfengUniversidad de los AndesFísicaFacultad de CienciasDepartamento de Físicainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaInverse perovskite solar cell stability using MoS2Trabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPCeldas solaresPerovskitaFísicaPublicationTHUMBNAILu821473.pdf.jpgu821473.pdf.jpgIM Thumbnailimage/jpeg6076https://repositorio.uniandes.edu.co/bitstreams/41fb27bd-b3f0-4c86-a439-de9467214895/downloadd007751b7ad815b94839a1a22465747aMD55ORIGINALu821473.pdfapplication/pdf11433368https://repositorio.uniandes.edu.co/bitstreams/efa81589-bab2-4501-b287-c0dfc7fa2844/download85153ea0068e229815b3f37c084d677cMD51TEXTu821473.pdf.txtu821473.pdf.txtExtracted texttext/plain47370https://repositorio.uniandes.edu.co/bitstreams/3723bdbf-7278-47f5-846f-7579f3d76a0a/download4dba333d9be7131f478a2c6e47dedb6fMD541992/39438oai:repositorio.uniandes.edu.co:1992/394382023-10-10 17:08:32.24http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |

The present thesis studies the fabrication and stability of organic-inorganic CH3NH3PbI3 solar cells. Due to their high reported efficiency and easy processability, photo-voltaics are being reinvented with perovskite technology. PVK's are fast producing, low cost, rapidly increasing efficiency technology. Their stability development could make photo-voltaics a viable alternative for energy production. By using a layer of MoS2, the perovskite is protected from moisture and ion migration from in the environment and the metal electrode. Using inverse architecture, the MoS2 is placed over the ETL layer (PCBM). This proved to be an effective treatment to conserve short circuit current (Isc) and maintained the shape of I-V curves, while non protected devices lost all their characteristics. |
