Background:Power Roll Ltd is a technology development company based in the North East of England. It is developing an innovative thin film photovoltaic (PV) technology that is based on 3D patterned substrate suitable for high throughput roll-to-roll (R2R) manufacturing. As part of its scale up development, it is looking to develop R2R deposition of Perovskite into its patented architecture. PRL technology has been demonstrated at +10% using spin coated perovskite into its flexible mini-module platform but is now in the process of scaling all process parameters to R2R.The project, located within SPECIFIC will involve working as part of Professor Trystan Watson's research group at Swansea. SPECIFIC is a National Innovation and Knowledge Centre led by Swansea University, working collaboratively with Universities across the UK. SPECIFIC has significant capability and expertise across its team and facilities; capabilities at SPECIFIC relate to the printing, coating and lifetime testing of functional materials and the development of enabling technologies that support the transition from laboratory bench to factory floor. The SPECIFIC PV scale-up and stability research activity is carried out in purpose-built facilities which include a new stability testing and cleanroom printing facility.Project Aims:During the 4 years, the project will involve;- Characterisation of Power Roll architecture structure including electrode and transport materials positions, thickness and properties.- Optimising perovskite formulation to match material architecture of PRLs substrates utilising standard spin coating deposition techniques.- Assisting the PRL team to develop optimised material architecture based on analysis form IV data.- Developing a process for scale up printing of perovskite to adequately fill PRL microgrooves architecture.- Developing optimised post processing of perovskite to accommodate variations in perovskite thickness.- Demonstrating scalability of printing process on large R2R format.- Transfering knowledge to PRL and assisting in purchase of equipment suitable for PRL scale up.
