Organic photovoltaic (OPV) technology promises a relatively inexpensive option for the solar energy conversion, provided its efficiency increases beyond the current level ( 7–8%) along with significant improvement in operational lifetime. To achieve this high efficiency/reliability, a systematic theoretical approach is required to optimize the underlying device fabrication process. In this arti...

The widespread introduction and adoption of renewable energy technologies remains high on virtually every national development policy agenda; renewable energy systems can assist national energy autonomy, decentralize resource management, promote environmental conservation, and serve as a means to reduce global warming. The track record of efforts to turn this noble ideology into successful tech...

Solar energy availability and high installation costs of photovoltaic system encourage to extract maximum power from solar radiation. Since conventional methods cannot differentiate change in power due to perturb voltage and changing weather condition, these algorithms are prone to change under varying climatic conditions. The proposed system presents the high efficiency maximum power point tra...

in recent year's renewable energy sources have become a useful alternative for the power generation. the power of photovoltaic is nonlinear function of its voltage and current. it is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (mpp) in various solar intensity. fuzzy logic controller has advantage in handling non-linear system. maximum power ...

Photovoltaic power generation is one of the ways using solar energy resources effectively. In recent years, it has received the world's attention and has been under rapid development. At present, one of the main problems faced by the photovoltaic power generation is the low conversion efficiency. One way to solve this problem is carrying out the maximum power point tracking in the photovoltaic ...

We show that thin film cadmium telluride (CdTe) solar cells exhibit the phenomenon of threshold switching similar to in phase change and resistive memory. It creates a conductive filament (shunt) through cell reaching buried electrode such as transparent oxide CdTe based photovoltaics (PV). While existing PV, was routinely contacted via laser scribe filled metals, our work paves way an alternat...
