About Program:
Perovskite–silicon tandem PV promises higher efficiencies and lower energy costs than conventional silicon, but its real-world success depends on proven reliability, clear bankability, and system-level integration. This program explores how tandem devices behave under operating conditions, how they impact balance-of-system design and performance, and how technical risks translate into investor confidence—supporting their transition from lab breakthroughs to dependable, financeable solar assets.
Aim: 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.
Program Objectives:
- 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.
What you will learn?
📅 Day 1 – Reliability & Qualification (Perovskite–Silicon Tandems)
- Tandem stack basics: optical/electrical coupling, tunnel junctions, interlayers
- Failure modes: ion migration, interdiffusion, UV/thermal/moisture stress, PID/LeTID, seal/encapsulant durability
- Test regimes & pathways to standards: DH/TC/HF/UV, light-soak, outdoor exposure → IEC 61215/61730 alignment
- Metrology essentials: junction-resolved IV, EQE/spectral mismatch, degradation (%/yr) estimation
- Hands-on: Draft a reliability test matrix & risk register for a sample tandem BOM (stresses, pass/fail, sampling, data logging)
📅 Day 2 – Bankability, Yield & Finance
- Bankability pillars: certification, field data, warranties, O&M assumptions, insurer/lender diligence
- Energy assessment: spectra & AOI impacts, temp coeffs, soiling/bifacial effects, uncertainty stacking
- Financials: LCOE drivers (CAPEX/BOS, yield, degradation, availability), PPA/insurance considerations
- Reliability → revenue bridge: mapping test results to yield-loss & risk narratives
- Hands-on: Build a mini bankability model (spectral correction + degradation) → LCOE sensitivity & warranty scenarios (one-page memo)
📅 Day 3 – BOS & Plant Integration
- Inverters/MPPT: tandem IV shape, wider MPPT windows, mismatch risk; DC:AC sizing & clipping
- Layout/trackers: spectral & AOI behavior, albedo choices, thermal effects; wiring/protection (fuses, AFCI, rapid shutdown)
- Interconnect & standards: commissioning/acceptance tests, SCADA/performance analytics, safety codes
- O&M: IV-curve scanning, condition-based cleaning, fault taxonomy, warranty evidence
- Hands-on: Quick BOS calc—select inverter MPPT window & DC:AC ratio for a tandem string, estimate clipping/losses, and define monitoring KPIs (yield, PR, degradation)
