A model to evaluate the effect of shading objects on the energy yield gain of bifacial modules
摘要： Bifacial modules become popular due to the backside yield gain, which can reduce the levelized cost of energy (LCOE) of photovoltaic system dramatically; the technical development of bifacial cell and double glass module technology are also important for the explosion of bifacial market. More and more people are attracted by the energy yield gain of bifacial modules; however, only little studies focus on the effect of backside shading objects on the module and system that would influence the energy yield gain. In this paper, an optic model is developed to evaluate the effect of the shading objects. The energy loss by the shading objects is also estimated by simulation and experiment. The result shows that when the shading objects are 40 mm vertical away from the modules, the shading effect could be greatly reduced. The frame height of bifacial modules should be smaller to reduce the shading effect by frames. It is better to remove the surface C of the frames to optimize the energy yield ability of bifacial modules.

[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Progress Towards a Non-Lamination Encapsulation Technology to Improve Reliability and Reduce Costs
摘要： New solar module architectures and manufacturing technologies are being developed that significantly reduce manufacturing costs and improve reliability. Variants for both crystalline silicon and thin film devices are being optimized. The outcome of this ongoing program will be a new module designs, streamlined manufacturing processes and accelerated stress results showing improved reliability. Prototype encapsulation process will demonstrate cycle time under 1 minute compared to the current industry method of vacuum lamination which takes more than 10 minutes. The new technology will significantly lower manufacturing costs, process time and reduce capital expenditures by approximately 3-5 times

Photovoltaic Module Reliability || What does the Future Hold for PV and a Brief Summary
摘要： The discussions in the previous chapters looked at both the history and present‐day status of photovoltaics (PV) module reliability and the accelerated stress testing associated with it. In this final chapter, the focus will shift to the future. PV is a dynamic industry so the technology and the testing standards are constantly evolving. The first section in this chapter will provide an update on the changes already in progress for some of the more important module qualification and safety standards. The second section will switch to a longer‐range view, discussing how PV module reliability is likely to change in the future and what sort of accelerated stress testing will be necessary to validate the quality of the huge volume of modules produced. The book will end with a brief summary of the status of PV module reliability today.
