Interaction Between Inorganic Compounds and Conjugated Polymers: Application as Hybrid Solar Cells and Hybrid Solar Sensors

摘要

In recent years the area of hybrid materials has encounter a growing interest due to the attractive new properties observed from the interaction of the organic and the inorganic counterparts. Some possible applications of these materials are batteries, fuel cells; supercapacitors, catalyst, membranes, sensors and biosensors among many others. Nevertheless, the application of these hybrid materials in solar-related applications is a relative new research area. Our interest relies on the study of the possible interaction between the light-harvesting properties of conjugated polymers and the wide band gap values observed from different inorganic empounds. We present here our most recent results of hybrid materials as part of photovoltaic devices and sensors. We have applied different semiconductor oxides together with the conjugated polymer MEH-PPV as solar cells and have found photovoltaic characteristics like V_(oc) as high as 0.9V, I_(sc) around 0.6 mA/cm~2 and fill factors as high as 44%. As hybrid solar sensors different inorganic materials have been applied (carbon nanotubes, inorganic semiconductors, metal nanoparticles, layered metal oxides, mixed ionic-electronic conductors, etc) together with light-harvesting conjugated polymers and found that a final multifunctional sensor can be obtained.
