D10.5 PROJECTED LEVELIZED COSTS OF ELECTRICITY FOR KEY DEVICE ARCHITECTURES

D10.5 PROJECTED LEVELIZED COSTS OF ELECTRICITY FOR KEY DEVICE ARCHITECTURES

The overall goal of the work package 10 is to provide guidance for the infrastructure and technology development within VIPERLAB by evaluating and optimizing the environmental, social and economic impact of new perovskite-based technologies. To this end, this work package will: • Provide the data (material, process flows etc.) necessary for such an evaluation • Evaluate the environmental (Life Cycle Assessment, LCA), social and economic (Levelized Cost of Electricity, LCOE) impact of new perovskite-based technologies and how this impact is affected by the application, device design, choice of equipment and process. This report presents the methodology followed to arrive at the projected levelized cost of electricity for the selected technology types, based on the key device architecture list detailed in deliverable report D10.1. The results of the LCOE (this report D10.5) and LCA (D10.4) are to be published in a peer reviewed journal as well as are aimed to be presented at an international conference in 2025. As such, this deliverable report will mainly focus on an introduction to the technologies evaluated and the methods followed to carry out the LCOE assessment and not contain any detailed results to maintain novelty and not hinder efforts to publish and/or present the results at a conference. However, the results of the analysis were presented and discussed with the project consortium at the final general assembly meeting held in Brussels in November 2024 and are briefly mentioned in this report. For both this report and deliverable report D10.4, detailing the environmental impact assessment, the methods followed to arrive at the results initiated from the same starting point. Firstly, Fraunhofer ISE’s in-house, bottom-up total cost of ownership model, “SCost” [1], was used to assess the production cost for the selected technology types – two crystalline silicon (c-Si) based single junction technologies - n-TOPCon and n-SHJ, and two 2-T perovskite-silicon tandem technologies - pero-TOPCon and pero-SHJ. Extending the production cost model to the LCOE assessment for the residential case, it was found that the pero-SHJ based tandem can provide the lowest LCOE compared to all other technology types. A sensitivity analysis with key parameter variation including the BOS costs, Global Horizontal Irradiation (GHI), system lifetime, degradation rate and module efficiency amongst others was also performed to see their individual impact on the LCOE of the pero-silicon tandems.
