A Study of the Electrical Output and Reliability Characteristics of the Crystalline Photovoltaic Module According to the Front Materials

open access: yesEnergies, 2020
In recent years, various types of installations such as floating photovoltaic (PV) and agri-voltaic systems, and BIPV (building integrated photovoltaic system) have been implemented in PV systems and, accordingly, there is a growing demand for new PV ...

An accurate method for the PV Model identification based on a genetic algorithm and the interior-point method

open access: yes, 2014
Due to the PV module simulation requirements as well as recent applications of model-based controllers, the accurate photovoltaic (PV) model identification method is becoming essential to reduce the PV power losses effectively.

Varying percentages of full uniform shading of a PV module in a controlled environment yields linear power reduction

open access: yesJournal of Energy in Southern Africa, 2016
Partial shading of a PV module has received much attention over the past few years, as it results in uneven cell power generation, compromising a PV system performance. Full uniform shading of a PV module has not received as much attention.

Domestic PV System with Feedback Linearization-based Control Strategy for Module-level MPPT under Partial Shading Condition

open access: yesJournal of Modern Power Systems and Clean Energy, 2021
A partial shading condition can adversely affect the energy conversion efficiency of domestic photovoltaic (PV) systems. Connecting each PV module to a microinverter and performing module-level maximum power point tracking (MPPT) are proposed as ...

Annual Prediction Output of an RADTIRC-PV Module [PDF]

open access: yesEnergies, 2018
The number of solar photovoltaic (PV) installations has been increasing worldwide but the high capital cost of installation continues to be the main challenge, particularly in many developing countries. The solar concentrator, a device that focuses the sunlight onto a small area, has the potential to minimize the use of expensive PV material while ...

Soiling and other optical losses in solar-tracking PV plants in Navarra

open access: yes, 2010
Field data of soiling energy losses on PV plants are scarce. Furthermore, since dirt type and accumulation vary with the location characteristics (climate, surroundings, etc.), the available data on optical losses are, necessarily, site dependent.

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

open access: yesMolecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Module Integrated PV Balancer for PV Applications

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2019
This paper presents the possibility of Module Integrated Converters (MIC) called PV balancers for photovoltaic applications. The proposed thought enables self-governing Maximum Power Point Tracking (MPPT) for each board, and radically decreases the requirements for power converters. The power rating of a PV balancer is under 20% of its accomplices, and

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.
