7-F020: Lateral optimisation of thin film dye-sensitised photovoltaics: Year 3 Final Technical Report

[摘要] The Specific Activities set out in the final year of the ARENA Fellowship 7-F020 Lateral optimisation of thin film dye-sensitised photovoltaics were successfully achieved. This Final Report details the achievement ofSpecific Activities: 5. Fabrication of demonstration modules with strip dimensions and cell spacing predicted from the optimisation model with enhanced performance relative to that of a simple geometric scaling of anequivalent-architecture test cell. Correlate module performance with that predicted by the optimisation model. In Year 1 of the project a DC equivalent circuit model applicable to the solid-state dye-sensitised solar cell was developed and the specific resistivities of each component quantified. In Year 2 of the project astraightforward empirical method for reliable evaluation of the remaining single diode parameters was developed. The efficacy of the progress made was also demonstrated via good empirical agreement withthe DC circuit model, and successful modelling of the I–V performance of single cells of area up to 1 cm2. The final year of this project is concerned with the translation of the 1 cm2 predictions to mini-modules of active area ≤64cm2, as per Specific Activity 5. Successful attainment of this goal is demonstrated across three Sections of this report. In Sections 4.1.2 we discuss the predictions of the lateral design model. In Section 5.2.1 we show the good correlation between the predictions of the lateral design model and experimental mini-modules; and in Section 5.3.1 we demonstrate the value of the lateral design model and module series interconnection in general by demonstrating that this strategy creates higher efficiency devices when fabricated at scale. Indeed, the mini-modules fabricated here display record power conversion efficiency for this technology, which is testament to the value of the lateral design model in intelligently designing the mini-modules and the high quality deposition methods used in their fabrication.In addition to the Activity 5 discussed above, a manuscript was required to be drafted on the topic of ‘the agreement of the model to module output to be prepared for submission to a suitable scientific journal’ tobe prepared for submission to a suitable scientific journal. To meet this task, the following manuscript is being prepared for submission in 2017:- T.W. Jones, B.C. Duck, R.B. Dunbar, K.F. Anderson, N.W. Duffy, G.J. Wilson “Highly efficient solid-state dye-sensitised solar cell mini-modules through informed device design with a lateral optimisation model”, to be submitted.o This manuscript details the work performed across all three years of this Project, from cell optimisation through model development, lateral optimisation and agreement to the model.The goal of this Fellowship was to develop a lateral optimisation algorithm for scale-up of solid-state dyesensitised solar cells (ssDSCs). This optimisation model will enable the informed lateral design of a minimodule to minimise where possible the losses that occur with upscaling. We have used the model to fabricate the most efficient ssDSC mini-modules reported to date. We anticipate that the model will proveuseful in designing perovskite mini-modules in the near future.
