Development and Characterization of Intermediate-Band Quantum Wire Solar Cells
… conversion of the intermediate band solar cell (IBSC). Time-resolved photoluminescence measurements showed that δ-doping can increase the lifetime of the excited electrons in the quantum wires. The quantum efficiency measurements revealed that the quantum wires extend the absorption spectrum in …

Análisis tomográfico a nanoescala de materiales nanoestructurados para dispositivos fotovoltaicos
… de banda intermedia con puntos cuánticos (QD-IBSCs) y para celdas solares de triple unión (3JSCs). Para ello, se ha realizado la caracterización estructural en 3D de heteroestructuras semiconductoras III-V por técnicas de tomografía electrónica (ET) y de tomografía de sonda atómica (APT). Así, …

Identifying the Processes of Value Co-Creation
… initiating, building, sharing and critiquing (IBSC). In the next stage, value is realized in the form of inter-related facets: knowledge, monetary, relationship, functional and experience value. All these value facets together increase or decrease the experience value. Once value is realized, …

Characterization of novel sb-nanostructures by transmission electron microscopy techniques for high efficient solar cells
… sub-bandgap currents is key for implementing the IBSC concept. On one hand, type-II energy band alignment as the obtained in GaAs1 xSbx/InAs QDs (x>0.16) is an effective measure, since it leads to longer carrier lifetimes. Additionally, denser QD structures must be required to achieve the …

The Role of Quantum Dot Size on the Performance of Intermediate Band Solar Cells
… quantum dot (QD) intermediate band solar cells (IBSCs). More specifically, the effect of indium arsenide (InAs) QD height on the open circuit voltage and solar cell efficiency was studied in a systematic way. To explore this effect in QD solar cells, several solar cells (SCs) were grown with …
