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这些新型光伏实施例中的一种类型-半透明模块-的相关参数，该模块在建筑集成光伏（BIPV）中有应用。这种光伏类型覆盖我们在城市的高大钢铁和玻璃建筑的潜力是巨大的，将可再生能源带到需要的地方，远离我们的农村地区。硅基光伏，就像我们经常在屋顶和田野上看到的面板一样，从多个角度来理解;基于位置的性能，由于安装角度导致的效率低下，预测年发电量以及更多标准。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资源来评估光伏系统对其能源状况的影响。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点和缺点。Polysolar Ltd是BIPV的专家，对使用我们的碲化镉（CdTe）光伏技术的半透明有着浓厚的兴趣，该技术为玻璃提供中性色调，从而减少室内的眩光和强度。然而，由于多种因素，如内反射、垂直取向和来自背面（非有源）侧的照明，这种类型的玻璃的部署还没有得到很好的理解。因此，当我们预测功率输出时，可能会不如我们所希望的那样准确，这可能会导致客户失望，并阻止他们在下一个建设项目中购买和使用这一关键技术。国家物理实验室（NPL）是测量专家，多年来一直参与光伏开发标准和测试方法，以确保所有技术都能公平地进行比较。他们的能力将定义所需的实验，以确定哪些因素影响这些CdTe光伏电池板在相关场景中的性能，从而更准确地预测性能。这将增加对该技术的信心并支持其采用。

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.
