¤ Objectives
It is the goal of this project and the general objective to make a step beyond the state of the art, to demonstrate the functionality of novel hybrid architecture based on flexible nanopatterned substrate (nanoSi) and graphene quantum dots (GQDs) for photovoltaic devices, by thoroughly understanding the properties of the resulting nanosystem, from both experimental and theoretical point of views.
Consequently, the main specific objectives are:
O1. Optimum design (density, exposed length/area) and easily reproducible technology for a flexible nanopatterned substrate (nanoSi)
O2. Engineered GQDs for matching electrical and optical properties for PV based on nanoSi;
O3. Methods for developing GQDs/nanoSi interface having the best quality required for PV applications;
O4.To corroborate and harmonize the methods, to test the resulting devices finally selecting the most adequate solution. In fact, the project objectives are encompassing the fundamental and technological knowledge and are parts of the functional model demonstration, one of this project claims being to offer theoretical support and technological alternatives easy adjustable in future generations of the photovoltaic devices.
Innovative solutions will be proposed to surpass the reported issues, giving the original and novel nature of the project:
- 0D graphene will be used instead of previously used graphene of 2D dimensionality, having the advantage over the previous ways as it allows more affordable functional groups
- functionalization of graphene nanodots that is expected to enhance charge carrier exchange with other solar cell layers, thus forming nanoheterojunction made of graphene dots and nanoSi
- PV devices made of GQDs and nanoSi can be miniaturized and integrated in buildings (BIPV) or textiles
- Si NW/NPL arrays is entangled with a flexible nanoSi substrate.
