A QDSC solar cell design that uses quantum dots as the absorbing photovoltaic material. It attempts to replace bulk materials such as Si, CIGS, CdTe ... etc. Quantum dots have bandgaps that are tunable across a wide range of energy levels by changing their size. In bulk materials, the bandgap is fixed by the choice of materials. This property makes quantum dots attractive for multi-junction solar cells, where a variety of materials are used to improve efficiency by harvesting multiple portions of the solar spectrum. The question is how we can calculate the structural, electrical and optical parameters of these nonomaterials using CASTEP. thanks for all.

Dear Idris,
Interesting subject! Well. As you know, CASTEP is a general purpose ab-initio quantum simulator, which can be used to simulate and obtain the energy band structure (electronic spectra) of different materials and structures. Therefore, you just need to suggest a suitable heterostructure (the QDSC to be studied) and consider swapping some important parameters to be optimized and have fun with CASTEP.
