Development of low band gap solar cell for thin film tandem application

Master projects/internships - Genk | More than two weeks ago

Help us develop the photovoltaic technology of tomorrow! 

Photovoltaics (PV) have the potential to produce electricity on a large scale and thereby help reducing the greenhouse gas emissions. Commonly seen examples of PV are large-scale solar farms or roof top modules based on Si PV. Supplementary to these examples, solar cells may also be integrated in buildings, cars, inhouse devices etc. For these latter options, highly efficient thin film (TF) PV can be used.  

One way to achieve highly efficient TF PV devices is to stack cells with different band gaps on top of each other. In this way both the photon energy as the number of photons in the solar spectrum are optimally used. At Energyville we are working on so-called tandem structures in which a high band gap solar cell on top absorbs the UV and visible light, leading to high voltage output and a low band gap cell at the bottom absorbs the NIR light. 
Within this project novel tandem architectures will be explored using chalcogen based materials (CuInSe2, AgBiS2) as bottom cell. Various synthesis routes will be explored and the materials will be investigated using SEM, EDX, photoluminescence, UV-VIS-NIR spectroscopy, XRD and more. Solar cell devices will be prepared and characterized with voltage-current measurements. 

This research will be performed at the EnergyVille laboratories in Genk, the PV laboratory from imec. IMOMEC (IMEC-Uhasselt) PV research teams are internationally recognized, thanks to its experts and world-class technology labs (Thin Film PV lab). The student has a background in physics, chemistry, nanomaterials or similar and interest in photovoltaics and experimental work.
