performance analysis for semi-transparent PV modules

太阳能光伏(PV)有各种新的形式和材料，允许一系列新的和令人兴奋的应用。在该项目中，合作伙伴关系旨在彻底测量其中一种新的光伏实施例--半透明模块--的相关参数，该模块在建筑集成光伏(BIPV)中具有应用。这种光伏类型在城市中覆盖高层钢铁和玻璃建筑的潜力是巨大的，将可再生能源带到需要它的地方，而不是我们的农村地区。基于硅的光伏，就像我们经常在屋顶和田野上看到的太阳能电池板一样，从多个角度得到很好的理解；基于位置的性能，由于安装角度而导致的低效率，年发电量的预测和更多的标准。由于这项出色的工作，任何对部署光伏系统感兴趣的人都可以使用在线可用的资源来评估光伏系统将对他们的能源状况产生的影响。对于比较不同类型的硅基光伏也是如此，因为新实施例的研究人员或开发人员可以突出特定系统的优缺点。PolySolar Ltd是BIPV领域的专家，使用我们的碲化镉(CdTe)光伏技术对半透明感兴趣，该技术为玻璃提供中性色调，从而减少房间内的眩光和强度。然而，由于内部反射、垂直方向和来自后方(非活动)侧的照明等多种因素，对于这种类型的玻璃的部署并不是很好的理解。为此，当我们预测功率输出时，它可能不像我们希望的那样准确，这可能会导致客户失望和气馁，不愿购买这项至关重要的技术，并将其包括在他们的下一个建设项目中。国家物理实验室(NPL)是测量专家，多年来一直参与光伏测试标准和方法的开发，以确保所有技术得到公平比较。他们的能力将定义所需的实验，以确定哪些因素在相关情况下影响这些CdTe光伏电池板的性能，从而导致对性能的更准确预测。这将增加人们对这项技术的信心，并支持它的采用。

Solar photovoltaics (PV) come in a variety of new formats and materials that allow for a whole range of new and exciting applications. In this project the partnership aims to thoroughly measure the relevant parameters of one type of these new PV embodiments -- a semi-transparent module -- that has applications in building integrated PV (BIPV). The potential for this PV type to clad our tall steel and glass buildings in cities is huge, bringing renewable energy to where it is needed and away from our rural areas.Silicon based PV, like the panels we regularly see on rooftops and in fields, are well understood from multiple viewpoints; location based performance, inefficiencies due to angle of installation, prediction of annual power yield and many more criteria. As a result of this good work anyone interested in deploying a PV system can use the resources available online to assess the impact a PV system will make on their energy profile. The same is true for comparing different types of silicon based PV as researchers or developers of new embodiments can highlight the up and downsides of a particular system.Polysolar Ltd are specialist in BIPV with a deep interest in semi-transparency using our cadmium telluride (CdTe) PV technology which gives a neutral tint to the glass thus reducing glare and intensity inside the room. However, the deployment for this type of glass is not as well understood due to multiple factors like internal reflection, vertical orientation and illumination from the rear (non-active) side. To this end, when we predict power output it may not be as accurate as we wish which can lead to clients being disappointed and discouraged from purchasing and including this vital technology in their next construction project.The National Physical Laboratory, NPL, are experts in measurements and have been involved with PV for many years developing standards and methodologies for testing to ensure all technologies are compared fairly. Their capabilities will define the experiments required to determine which factors influence the performance for these CdTe PV panels in relevant scenarios, leading to more accurate predictions of performance. This will increase the confidence in the technology and support its uptake.
