This work presents the concept of a monolithic concrete-integrated dye-synthesized photovoltaic solar cell for optical-to-electrical energy conversion and on-site power generation. The transport measurements carried out in the dark revealed the presence of VOC of ~190 mV and ISC of ~9 μA, induced by the electrochemical conversion of concrete-supplied ionic impurities at the electrodes. The curr...

Semiconductor devices with enhanced efficiency, resilience, and/or optimized to specific applications/environments rely increasingly on the incorporation of III-V random alloys that have been engineered to possess certain required optoelectronic properties. When these materials are grown, however, challenges with non-random elemental arrangements can greatly affect – and in some cases eliminate...

Nowadays, computer modeling provides a fantastic tool to decrease cost, optimize design, and reduce turnaround times of any product. Analysis of microelectronic and photonic structure – 1D (AMPS-1D) presents one of many attempts to unite numerical modeling and the physics of photovoltaic (PV) cell into one software package where the PV device model appears as a planar, layer-by-layer cell. This...

Cadmium telluride (CdTe) has been recognized as a promising photovoltaic material for thin-film solar cells because of its near optimum bandgap of ~1.5 eV and high absorption coefficient. The energy gap is near optimum for a single junction solar cell and the high absorption coefficient allows films as thin as 2 μm to absorb more than 98% of the above-bandgap radiation. Cells with efficiencies ...

This strategy is based on Fuzzy Logic Control technique. The hybrid power system is sized to provide the energy demand of the inhabitants of the house and if there is an extra power ge...

Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell. The system consists of an eight-fold Fresnel lens as a primary optical element (POE) ...
