To search the optimum solutions for increasing of electric energy generation efficiency in the Photovoltaic System is the topic of this paper. There are four cases to improve the efficiency of power producing from the Photovoltaic System. This article not only describes the differences of facilities before and after the proposal, but also evaluates the electric energy generation efficiency and improved...
In order to understand how users interact with PV-powered products, the behavior of 100 people was observed and analyzed, while interacting with 6 different photovoltaic-powered products in their daily life. The sample of users to be observed consisted of 20 groups, each one formed by 5 students of the Industrial Design Engineering Department of TU Delft in the Netherlands. The tested PV products...
In an effort to further advance a realizable form of wireless power transmission (WPT), high intensity laser power beaming (HILPB) has been developed for both space and terrestrial applications. Unique optical-to-electrical receivers are employed with near infrared (IR-A) continuous-wave (CW) semiconductor lasers to experimentally investigate the HILPB system. In this paper, parasitic feedback, uneven...
Partially shaded conditions are common in all kinds of PV systems. The mismatch phenomenon of a Solar PV array, such as partial shade, not only affects the power generated by solar system, but also leads to safety and reliability problems. This paper proposes a new shading degree model-based self-adaptive reconfiguration method to reduce the effect of shadows on solar arrays. A switching matrix dynamically...
Organic photovoltaics are being explored for powering electronic devices by harvesting the sun's energy or indoor lighting. Such solar cells have shown promise as they can be deposited on thin flexible foils that enable flexibility of integration within products while keeping the weight light. Several R&D efforts are underway in creating improved organic solar cells in terms of their efficiency...
With the daily worsening of global energy crisis and environmental pollution, characteristics of the non-pollution, non-noise and non-raw material except the sun of photovoltaic generation make it a promising green energy. This paper proposes a strategy of photovoltaic lighting system with energy management and control, which includes maximum power point tracking sub-battery charge control and battery...
