NAno-buildiNg blOcks based on octahedraL molybdEnum clusTers for the design of Structured inorGanic phOtoelectrodes for Solar energy conversion – NanoLEtsGOs

NanoLEtsGOs is a multidisciplinary project aiming at designing original inorganic photoelectrodes built from abundant metal and low-toxic metal cluster (MC)-based nanobuilding blocks. MCs will be used as new light-harvesters to propose innovative, clean and efficient devices for sunlight conversion applications. NanoLEtsGOs will develop all inorganic solar cells reaching photoconversion efficiency above 10% by optimizing the optoelectronic properties of photoactive layers, based on the controlled assembling of MC building blocks, in terms of light absorption and transport properties. NanoLEtsGOs will implement 3 strategies to improve light absorption and transport properties within the photoactive layers: i) the progressive substitution of halogen ligands by sulfur ligands in order to form bridges between MCs, ii) the integration of the MCs into a (semi)conductive polymeric matrix and/or iii) the structuration of the light-harvester layer.
