The Situation / Challenge
Perovskite solar cell technology has generated genuine scientific excitement and an accompanying wave of investment activity, but the gap between laboratory efficiency records and commercially viable, bankable manufacturing processes remains one of the most consequential and least transparent questions in the clean energy investment landscape.
The client’s investment committee was evaluating a growing pipeline of perovskite opportunities, each presenting efficiency data and commercialisation timelines that were difficult to independently verify.
The risk was not merely making a poor individual investment decision — it was developing an evaluation framework systematically biased toward whichever opportunities presented the most polished narrative rather than the most credible underlying manufacturing readiness, a bias that would compound across the fund’s full perovskite allocation.
Key Challenges
- No independent technical assessment distinguishing genuine commercialisation readiness from favourable presentation of early-stage laboratory results
- No structured framework for comparing single-junction perovskite cells against tandem architectures on a consistent, evidence-based timeline
- No direct intelligence from manufacturing executives, equipment suppliers, and module integrators on the actual operational constraints limiting commercial-scale production
- An existing diligence process built for conventional clean energy hardware, not well calibrated to evaluate emerging cell technology where claims and readiness diverge
- Risk that investment decisions were being influenced more by pitch quality and narrative framing than by verified operational evidence
- Limited partner expectation that the fund’s perovskite allocation decisions reflect rigorous, independently verified technical diligence rather than reliance on company-provided claims
Emerging cell technology investment decisions are particularly vulnerable to a gap between what laboratory results demonstrate and what manufacturable, bankable products actually require. Independent primary research with the people closest to manufacturing operations — rather than company-provided pitch materials — is frequently the only reliable way to close that gap before capital is committed.
Constancy Researchers Solution
Constancy Researchers designed the engagement specifically to separate verified operational evidence from presentation quality, going directly to manufacturing operations rather than relying on company-provided pitch materials.
Global Perovskite Solar Cell Market & Commercialisation Readiness Assessment
- Delivered a market research report assessing the global perovskite solar cell landscape — covering single-junction and tandem architecture development, manufacturing scale-up, and stability data
- The research identified that perovskite-silicon tandem cells had achieved more consistent verified stability results than single-junction products, reframing the committee’s prior assumption
In-Depth Interviews (IDIs) with Perovskite Manufacturers & Tandem-Cell Developers
- Conducted 14 IDIs with manufacturing and technical leadership at perovskite and tandem-cell developers, exploring production yield and realistic commercial-volume timelines
- IDIs consistently identified manufacturing yield variability and long-term module-level moisture stability — rather than cell efficiency — as the binding constraints
In-Depth Interviews (IDIs) with Equipment Suppliers
- Conducted 11 IDIs with equipment suppliers serving the perovskite manufacturing ecosystem, assessing which developers had genuinely scalable production processes
- Equipment supplier perspective provided an unusually candid, cross-customer view of manufacturing readiness, since suppliers worked across multiple competing perovskite developers
In-Depth Interviews (IDIs) with Module Integrators
- Conducted 10 IDIs with solar module integrators evaluating perovskite and tandem cell technology for inclusion in their own product roadmaps
- Module integrator IDIs revealed that the qualification bar for bankable, insurable commercial deployment was meaningfully higher than the efficiency-focused pitch narrative
Revised Diligence Framework & Investment Evaluation Criteria
- Synthesised market research and IDI findings into a revised technical diligence framework weighting manufacturing yield and verified stability evidence above efficiency claims
- Delivered a structured evaluation scorecard the investment committee could apply consistently across its perovskite pipeline, replacing reliance on company-provided narrative
The engagement gave the investment committee what its existing process could not — an independently verified view of manufacturing readiness that did not depend on the persuasiveness of any individual company’s pitch.
Impact
- Market research reversed the committee’s working assumption about tandem versus single-junction readiness
- Manufacturer IDIs identified yield variability and module-level stability as the actual binding constraints
- Equipment supplier IDIs provided a cross-customer manufacturing readiness comparison unavailable from any single source
- Module integrator IDIs revealed the genuine commercial qualification bar, exposing a gap with pitch claims
- The revised diligence framework gave the committee a consistent, evidence-based evaluation tool
- Two portfolio companies were advanced to term sheet discussions on the strength of the evidence
- One previously favoured opportunity was declined after the framework exposed unresolved stability concerns
- Limited partners received an enhanced diligence methodology that strengthened confidence in the fund’s process
Client Outcome
Diligence Quality
The investment committee adopted a revised framework grounded in independently verified manufacturing evidence.
Investment Decisions
Two opportunities advanced to term sheet discussions and one was declined, reflecting manufacturing readiness evidence.
Technology Reassessment
The committee corrected its prior assumption about single-junction versus tandem cell commercialisation timing.
Risk Avoidance
The declined opportunity's unresolved manufacturing concerns were identified before capital commitment was made.
Evaluation Consistency
A structured scorecard gave the committee a repeatable basis for comparing future perovskite opportunities.
Limited Partner Confidence
The enhanced diligence methodology strengthened limited partner confidence in the fund's investment process.
Manufacturing Insight
The fund gained an independent, cross-ecosystem view of perovskite manufacturing readiness that no single company's pitch.
Process Improvement
The revised framework was adopted as the standard diligence approach for future emerging solar technology evaluation.
Market Positioning
The fund was repositioned as an investor with genuine technical diligence capability in emerging cell technology.
