System efficiency and cost effectiveness are of critical importance for photovoltaic (PV) systems. This paper addresses the two issues by developing a novel three-port DC-DC converter for stand-alone PV systems, based on an improved Flyback-Forward topology. It provides a compact single-unit solution with a combined feature of optimized maximum power point tracking (MPPT), high step-up ratio, g...

This paper presents a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a Sinusoidal Pulse Width-Modulated (SPWM) control scheme. The photo-voltaic arrays are connected to fivelevel multilevel inverter through the DC-DC boost converter. By implementing maximum power point tracking algorithm are producing more power from PV array. The DC power from th...

Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevert...

The light absorption of a monolayer graphene-molybdenum disulfide photovoltaic (GM-PV) cell in a wedge-shaped microcavity with a spectrum-splitting structure is investigated theoretically. The GM-PV cell, which is three times thinner than the traditional photovoltaic cell, exhibits up to 98% light absorptance in a wide wavelength range. This rate exceeds the fundamental limit of nanophotonic li...

One way to minimize costs of photovoltaic (PV) systems is that of maximizing their energy production, per kW of installed power and for a fixed solar irradiation (SI) and temperature. For this reason, in the specialized literature, a great attention has been devoted to researches on efficient techniques able to continuously track the maximum power point (MPP) of the photovoltaic generator (PG)....

To employ new solar photovoltaic technologies in products and buildings, many systems need to be adapted. Inspired by the cylindrical shape, in this work we have evaluated the performance of luminescent solar concentrator photovoltaic (LSC-PV) elements with narrow PV cell strips that could be integrated in an outdoor lighting pole. Silicon photovoltaic (PV) cells were attached to the back of bo...

A feed-in tariff system and a subsidy are often used to make households install photovoltaic (PV) systems for solar power generation. They both influence the economics of a household in deciding whether to install or not. The purpose of this study is to obtain information on how a PV-power price and a subsidy should be set to promote adoption of PV systems effectively and efficiently. The model...
