NSG/Pilkington is one of the largest glass manufacturers in the world. With a strong presence in Europe and manufacturing sites in the UK, NSG produces over 320million M2 of glass products every year. NSG produces glass for markets such as automotive, display and optical products and in considerable volume for the built environment. NSG seeks to add value to their current building integrated glazing range by extending their current functionality from such things as low emissivity and self-cleaning to that of energy (electricity) generation. A range of different options are available including opaque application of existing PV technologies for spandrel panels however of interest in this project is the delivery of a PV technology that is also semi-transparent and that can be used in conventional glass window products. An exciting new technology which may deliver this is the printable perovskite solar cell. Current champion performances of perovskite solar cells have reached over 22% in efficiency and continue to rise, this is achieved whilst using low cost materials that can be applied using industry scale deposition methods. The challenge of this project is to achieve a scaled glazing product using perovskite that is also semi-transparent, this requires additional technology innovation in the area of the perovskite absorber layer itself as well as in the normally opaque electrode materials.This EngD represent an exciting opportunity to work within the PV group at SPECIFIC, led by Dr Trystan Watson and further the ambitions of NSG to develop a solution processable solid state semi-transparent solar glass product. The SPECIFIC IKC sits beyond fundamental science to identify the technologies emerging from laboratories and assess their suitability to scale up in the area of building integrated functional coatings that generate, store or release energy. The photovoltaic group has responsibility for identifying new cell architecture and chemistries that fit with the necessary criteria of large scale manufacture which includes earth abundance, manufacturing feasibility and impact on the environment.Project Aims:The aim of this project is to develop a semi-transparent prototype glazing product based on the perovskite solar absorbing material. This will entail the development and optimization of strategies to balance light absorption by the absorber material whilst maintaining semi-transparency of the glass overall and the ability to influence the overall absorption wavelengths (colour) and clarity of the device stack. It will be necessary to develop appropriate absorber and electrode materials for this purpose. In addition the methods that will be developed will require application using scalable processes such as blade coating or slot-die onto industrially relevant NSG products.

NSG/Pilkington是世界上最大的玻璃制造商之一。凭借在欧洲的强大影响力和在英国的制造基地，NSG每年生产超过3.2亿平方米的玻璃产品。NSG为汽车、显示器和光学产品等市场生产玻璃，并为建筑环境生产相当数量的玻璃。NSG寻求通过将其当前的功能从低发射率和自清洁功能扩展到能源(电力)发电来为其当前的建筑集成玻璃系列增加价值。有一系列不同的选择可供选择，包括不透明地应用现有的光伏技术用于悬臂板，然而，该项目感兴趣的是提供一种也是半透明的、可用于传统玻璃窗产品的光伏技术。一项令人兴奋的新技术可能会实现这一点，那就是可打印的钙钛矿太阳能电池。目前，钙钛矿型太阳能电池的最佳性能已经达到了22%以上的效率，而且还在继续提高，这是在使用可以使用工业规模沉积方法的低成本材料的情况下实现的。该项目的挑战是使用钙钛矿实现半透明的规模化玻璃产品，这需要在钙钛矿型吸收层本身以及通常不透明的电极材料领域进行额外的技术创新。这是一个令人兴奋的机会，可以在Trystan Watson博士领导的光伏小组内部工作，并进一步实现NSG开发可溶液处理的固态半透明太阳能玻璃产品的雄心。具体的IKC超越了基础科学，以确定实验室正在出现的技术，并评估它们在构建产生、储存或释放能量的集成功能涂层领域的适宜性。光伏小组负责确定新的电池结构和化学物质，以满足大规模生产的必要标准，包括地球丰度、制造可行性和对环境的影响。项目目标：该项目的目标是开发基于钙钛矿型太阳能吸收材料的半透明原型玻璃产品。这将需要制定和优化策略，以平衡吸收材料对光的吸收，同时保持玻璃的整体半透明，以及影响设备堆栈的整体吸收波长(颜色)和清晰度的能力。为此，有必要开发合适的吸波材料和电极材料。此外，将开发的方法将需要使用可扩展的工艺，如刀片涂层或缝隙模具，应用到与工业相关的NSG产品上。
