Self-Cleaning Microcavity Array for Photovoltaic Modules

ACS Applied Materials & Interfaces, 2018
Development of self-cleaning coatings is of great interest for the photovoltaic (PV) industry, as soiling of the modules can significantly reduce their electrical output and increase operational costs. We fabricated flexible polymeric films with novel disordered microcavity array (MCA) topography from fluorinated ethylene propylene (FEP) by hot ...

Module to array design for bifacial photovoltaics

OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019
Here, I discuss the potential for designing bifacial photovoltaic modules to balance electrical and optical losses using interdigitated back contacts, and then extend this concept to the bifacial panel arrays.

Removal of the hot-spot problem in photovoltaic modules and arrays

Solar Cells, 1991
Abstract High power photovoltaic generators are installed nowadays. Reliability of continuous operation of this system is the prime consideration. Shadowing and thermal disequilibrium are the major constraints. Shadowing is the normal event in a photovoltaic system, causing thermal disequilibrium which produces excess heat at the shadowed cell.

Encapsulated photovoltaic blankets and modules for deployable solar arrays

2015 IEEE 42nd Photovoltaic Specialist Conference (PVSC), 2015
Large-area deployable solar arrays offer sizable advancements in stowed volumetric power and as-deployed specific power compared to conventional rigid solar arrays, but the traditional cell-interconnect-coverglass (CIC) scheme is no longer optimized for these embodiments.

Modified particle swarm optimization method for MPPT in photovoltaic module arrays

2016 IEEE 14th International Conference on Industrial Informatics (INDIN), 2016
This paper first is to study the output characteristics of partial photovoltaic module array under shading. Then, it applies the modified particle swarm optimization (MPSO) to track the maximum power point (MPP) of characteristic curve with peaks. The MPSO makes the weighting and cognition learning factor decrease along with the increasing of iteration

Analysis of photovoltaic array with reconfigurable modules under partial shading

2012 38th IEEE Photovoltaic Specialists Conference, 2012
Partial shading across solar arrays can significantly deteriorate maximum generated power. Typical arrays implementing a parallel-in-series architecture have bypass diodes integrated in the modules to reduce the effects of partial shading. In this paper, analysis is performed on the effectiveness of improving maximum power of a solar array comprising ...

Flexible fluorine-based micro-lens arrays for photovoltaic modules

2012 IEEE Nanotechnology Materials and Devices Conference (NMDC2012), 2012
We present the first flexible micro-lens arrays designed for photovoltaic modules that utilize fluorine-based film. These micro-lens are fabricated as a key component of increasing electric generation in the fluorine-based film. The rigorous coupled wave analysis (RCWA) method was used for optical simulation.
