We study a model-based approach to detect sustainable faults of photovoltaic systems. We describe models and algorithms which allow us to analyze a large amount of photovoltaic systems. Our approach is based on median regression. We assume that we know the irradiance and produced energy of a photovoltaic system. The particular challenge of the data analysis problem we study here is the possible...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

in this investigation, ag@tio2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial tio2 nanoparticles (known as p25 tio2) via photodeposition technique as clean and simple photochemical route. the synthesized ag@tio2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (dssc) chiefly because, compared to pure tio2, the electron affinity of ag@ti...

With the rapid development of the photovoltaic industry, fault monitoring is becoming an important issue in maintaining the safe and stable operation of a solar power station. In order to diagnose the fault types of photovoltaic array, a fault diagnosis method that is based on the Least Squares Support Vector Machine (LSSVM) in the Bayesian framework is put forward. First, based on the elaborat...

There are 1.3 billion people living without electricity, a large portion of which is in the bottom of the economic pyramid. Rural electrification via photovoltaic systems is one possible solution to alleviate their poverty. The aim of this article is to qualitatively investigate the potential for the transition towards off-grid photovoltaic systems. Two interrelated aspects are specifically inv...

A novel theory of acoustics in solar energy supporting the principle of source and sink of solar energy is presented. The significance of the theory is in ascertaining the aftermaths of turning off solar energy. An amplifier constituting of a parallel plate photovoltaic device connected to a potentiometer is illustrated. It was constructed with a pair of glass coated photovoltaic modules and po...

We investigate the quantum photovoltaic effect in double quantum dots by applying the nonequilibrium quantum master equation. A drastic suppression of the photovoltaic current is observed near the open circuit voltage, which leads to a large filling factor. We find that there always exists an optimal inter-dot tunneling that significantly enhances the photovoltaic current. Maximal output power ...

Bismuth ferrite (BiFeO3) thin films were prepared by a spin-coating method. Crystal structure and optical properties of the BiFeO3 films were evaluated using X-ray diffraction. The lattice constants, crystallite size, and energy gap of BiFeO3 films depended on the concentration of the BiFeO3 precursor solution. BiFeO3/CH3NH3PbI3 photovoltaic devices were fabricated to investigate photovoltaic p...
