Rapid processing of perovskite thin films for applications in PV

Druffel T., Lavery B., University of Louisville, US

Perovskite solar cells have the possibility of becoming the next generation of industrial solar cells due to their ease of manufacturing, use of common materials, and respectable efficiencies. Since the first report of perovskite solar [...]

Solar Energy System Prototype with a Maximum Power Point Tracking (MPPT)

Abdelmoaty A.A., Helmy A., Rezk A.A., Ismail Y., The American University in Cairo, EG

The paper shows the design and implementation of a novel power management unit that combines (mixes) several power harvesting sources and delivers (routes) the power to the working load and the battery. The system can [...]

c-SI Wafer Development: A New Approach to Reduce Costs and Drive Efficiency

Zehavi S., Rockpoint PR, US

The global solar photovoltaic (PV) market is predicted to increase by double digits between 40-45 GW in 2014, according to a forecast from IHS Inc. And by 2015, new installations could reach as high as [...]

Carriers Transport in Quantum Dot Quantum Well Microstructures of Self-assembled CdTe/CdS/ligand Core-shell System

Li K., Yanshan University, CN

The photo-generation carriers’ transport characteristics in CdTe quantum dots (QDs) capped by ligand were probed using a combination of surface photovoltaic (Figure 1) and photoacoustic techniques. The results confirmed that the QDs were composed of [...]

Surface Passivation of GaAs Nanowires Ensembles for Photovoltaic Applications

Chia A.C.E., LaPierre R.R., McMaster University, CA

Fabrication, electrical characterization and analytical modeling of an AlInP-passivated GaAs NW ensemble is presented. Novel processing steps were used to fabricate NW ensemble devices which were subsequently characterized electrically and fit with an analytical model, [...]

Effects of ZnO buffer layer and depth profiling analysis of bulk heterojunction organic solar cells

Mbule P.S., Kim B.S., Kim T-H., Kim B.S., Kim T-H., Swart H.C., Ntwaeaborwa O.M., University of the Free State, ZA

Bulk heterojunction organic solar cells (BHJs) with ZnO nanoparticles buffer layer between the active layer and the aluminum (Al) top electrode were fabricated. The BHJs comprised of successive layers of poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a blend of [...]

Silicon Solar Cell Efficiency Improvement Through Advanced Cleaning Technology

Bohling D.A., Goldstein A., Treichel H., Lizard T., George M.A., Sunsonix, US

Sunsonix™ has identified a technology gap/need in the area of crystalline silicon photovoltaic efficiency and field degradation. The cause of both poor efficiency and rapid degradation may share common roots, that being trace contamination at [...]
