Triple-junction tandem solar cells: structural and spectral optimization for improved current matching and efficiency
In this work, a triple-junction tandem solar cell (TSC) has been designed in order to increase the photovoltaic (PV) performance through utilizing maximum light photons. To create three junctions in this work three subcells have been designed and optimized at its best PV performance. The optimization of all the three subcells have been done through the various variations in the absorber layer like thickness and bulk defect density (BDD). It has been seen that best PV parameters in the top middle and bottom cell are maximum at high thickness and low BDD. For the designing of triple junction tandem configuration, two filtered spectrums (FS1 and FS2) have been calculated for the proper current matching in the three subcells. The optimized triple-junction TSC demonstrates significantly enhanced PV parameters, including high open-circuit voltage (VOC- 2.750), short-circuit current density (JSC- 16.45 mA/cm2), fill factor (FF- 83.40%), and power conversion efficiency (PCE- 37.74%). The strategy of using filtered spectrums and exact design optimization provides a potential road to the next generation of high-efficiency tandem solar cells, furthering the field of renewable energy solutions.
期刊介绍：
Energy is the single most valuable resource for human activity and the basis for all human progress. Materials play a key role in enabling technologies that can offer promising solutions to achieve renewable and sustainable energy pathways for the future.
Materials for Renewable and Sustainable Energy has been established to be the world''s foremost interdisciplinary forum for publication of research on all aspects of the study of materials for the deployment of renewable and sustainable energy technologies. The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production. It publishes reviews, original research articles, rapid communications, and perspectives. All manuscripts are peer-reviewed for scientific quality.
Topics include:
1. MATERIALS for renewable energy storage and conversion: Batteries, Supercapacitors, Fuel cells, Hydrogen storage, and Photovoltaics and solar cells.
2. MATERIALS for renewable and sustainable fuel production: Hydrogen production and fuel generation from renewables (catalysis), Solar-driven reactions to hydrogen and fuels from renewables (photocatalysis), Biofuels, and Carbon dioxide sequestration and conversion.
3. MATERIALS for energy saving: Thermoelectrics, Novel illumination sources for efficient lighting, and Energy saving in buildings.
4. MATERIALS modeling and theoretical aspects.
5. Advanced characterization techniques of MATERIALS
Materials for Renewable and Sustainable Energy is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies
