Perovskite–Silicon Tandem PV: Reliability, Bankability, and Balance-of-System Impacts

To critically examine the reliability, bankability, and balance-of-system implications of perovskite–silicon tandem photovoltaic (PV) technologies, with a focus on translating high-efficiency cell performance into robust, low-risk, and financeable real-world solar projects.

• To provide an integrated view of perovskite–silicon tandem PV from cell/module design to utility-scale plant deployment.
• To map key reliability and qualification requirements for tandems and position them against existing IEC/UL standards and test regimes.
• To establish clear links between lab/field reliability data and bankability metrics such as yield, degradation, warranties, and LCOE.
• To highlight BOS and plant-integration implications of tandem technology, including inverters, layout, protection, monitoring, and safety codes.
• To build a common language between R&D, project development, and finance teams for evaluating tandem PV risk and opportunity.
• To equip participants with practical templates (test matrix, risk register, mini bankability model, BOS KPIs) that can be adapted to real projects.

• PV cell/module R&D engineers working on perovskite, silicon, or tandem architectures
• Reliability & test engineers in PV manufacturing, certification labs, or QA teams
• Project developers, IPPs, EPCs & asset managers involved in utility-scale solar projects
• Technical advisors, lenders, insurers & investors evaluating PV technology bankability
• Policy, standards & regulatory professionals focused on solar qualification and safety codes
• Faculty, PhD/PG students in renewable energy, materials, or power systems; final-year UG students are welcome if they have prior exposure to basic PV concepts (IV curves, efficiency, LCOE).

• Understand the architecture and failure modes of perovskite–silicon tandem stacks, and how these differ from conventional silicon PV.
• Design a reliability and qualification test matrix for tandem modules aligned with IEC 61215/61730 and related standards.
• Interpret junction-resolved IV/EQE data, estimate degradation rates (%/year), and link these to field performance expectations.
• Evaluate the bankability of tandem PV projects by connecting reliability evidence, yield assessments, and financial metrics (LCOE, PPA, warranties).
• Quantify key yield drivers for tandem plants, including spectral effects, temperature behavior, soiling, and DC:AC sizing/clipping.
• Specify BOS and plant-integration requirements (inverters/MPPT windows, layout/trackers, wiring, SCADA, safety codes) tailored to tandem technology.
• Develop practical tools such as a tandem reliability risk register, a mini bankability model, and BOS/monitoring KPIs that can be adapted to real projects.
