Tata Steel would like to understand the potential of adding photoactive energy generation materials to a portfolio of steel products to achieve added value. This entails the sequential deposition of functional layers onto pre-existing architectural products culminating in a completed photovoltaic product appropriate for direct integration into the built environment. The proposed technology of choice is that of the perovskite solar cell. Perovskite solar cells (PSCs) as solid state devices have demonstrated the highest efficiency of all printed solar cell technologies. The current record for a small area PSC now stands at 25 %. These small area devices are often processed with an evaporated gold or silver top electrode which can add significantly to the cost of the devices and render the device stack inappropriate for mounting onto an opaque substrate. This means that generally speaking most perovskite cell architectures are inappropriate for metal or steel based substrates. The world's first perovskite solar cell made using a metal substrate was developed and published by Swansea University (see Troughton et al, Highly efficient, flexible, indium-free perovskite solar cells employing metallic substrates, J Mat Chem A 2015, 3, 9141). There are two possible approaches for deploying a PV product onto a steel substrate:1. Direct application of layers sequentially onto the metal itself, whereby the metal substrate acts as an electrode in the device stack. This could be a metal foil material that is then subsequently laminated to a more appropriate architectural steel. 2. Application of an electrically insulating layer to an organically coated steel product that is then further functionalised with an electrically conducting layer and then sequentially applied photoactive materials. The device is then completed with a transparent conducting layer and barrier film.The research will involve consideration of these approaches and collaboration with the existing research team to develop a pathway to a printed solar cell demonstrator on steel substrates.

塔塔钢铁公司希望了解在钢铁产品组合中添加光敏发电材料以实现附加值的潜力。这需要将功能层顺序沉积到现有的建筑产品上，最终形成适合直接集成到建筑环境中的完整光伏产品。建议选择的技术是钙钛矿太阳能电池。作为固态器件的钙钛矿太阳能电池（PSC）已证明是所有印刷太阳能电池技术中效率最高的。目前小面积 PSC 的记录为 25%。这些小面积器件通常采用蒸发的金或银顶部电极进行处理，这会显着增加器件的成本，并使器件堆叠不适合安装到不透明基板上。这意味着一般来说大多数钙钛矿电池结构都不适合金属或钢基基材。世界上第一个使用金属基板制成的钙钛矿太阳能电池由斯旺西大学开发并发表（参见 Troughton 等人，Highly effective,flexible,indium-free perovskite Solar cells using Metal Bases, J Mat Chem A 2015, 3, 9141）。将光伏产品部署到钢基板上有两种可能的方法：1。按顺序将各层直接施加到金属本身上，从而使金属基板充当器件堆栈中的电极。这可以是金属箔材料，然后层压到更合适的建筑钢上。 2.将电绝缘层施加到有机涂覆的钢产品上，然后用导电层进一步功能化，然后顺序施加光活性材料。然后，该设备配有透明导电层和阻挡膜。该研究将考虑这些方法并与现有研究团队合作，开发在钢基板上印刷太阳能电池演示器的途径。
