Subject: [Special Feature] The Era of Flexible Solar Cells Unveiled by Japan’s New NEDO Guidelines – SUNFOREST Perovskite Product Lineup
I. Policy Background: Japan Breaks Through Physical Limitations
In March 2026, NEDO announced new design and construction guidelines for flexible solar cells.
1. Background: Land and rooftops suitable for conventional panels are nearly exhausted
2. Objective: Accelerate commercialization of lightweight, flexible thin-film technology (perovskite)
3. Impact: Enables installation on building facades and low-load-bearing roofs → creates new incremental market
II. Technical Significance: A Step Toward Energy Independence
1. Challenge with conventional type: Heavy weight makes installation on lightweight roofs and vertical walls difficult
2. Advantage of flexible type: Lightweight and bendable → transforms building facades and non-load-bearing roofs into "power plants"
3. Future outlook: Integration with battery storage to build decentralized energy networks
III. SUNFOREST Perovskite Product Lineup
(1) Flexible Type (Curved Surface Compatible, Lightweight)
1. 300×300mm (1.7mm): 8.5W – 14.5W (consumer electronics, IoT, sensors)
2. 400×1000mm (1.7mm): 50W – 70W (mobile power, outdoor equipment)
3. 800×1000mm (1.7mm): 95W – 155W (curved roofs, vehicle integration)
4. 1600×1000mm (1.7mm): 195W – 315W (large-area curved installation, max efficiency 21%)
5. 1200×1600mm (1.0mm): 260W – 300W (industry's largest size, ultra-thin & lightweight)
Common features: 1/10 to 1/5 weight of conventional panels, IP68, hail resistance (25mm / 23m/s)
(2) Rigid Glass Surface Standard Type (High Efficiency, High Reliability)
1. 1200×600mm (7mm): 110W – 130W (efficiency 15.3% – 18.1%)
2. 1200×1600mm (12mm): 185W – 210W (translucent/color type, BIPV facade)
3. 1223×2308mm (35mm): 430W – 500W (ground-mounted, industrial roofs)
Common features: IEC61215/61730 certified, 12-year product warranty, 25-year linear power warranty
(3) Perovskite BIPV (Building-Integrated Photovoltaics)
1. Power-generating stone: 85W – 105W (solid/color), 75W – 95W (stone grain) / building-material-level durability
2. Power-generating curtain wall: 75W – 95W, 10% – 50% transmittance / color and size customizable
3. Solar roof tiles: 822×822mm, curved design / waterproof, anti-glare, replaces conventional roofing
4. Integrated industrial roof: Color steel sheet integrated design, wind pressure resistance 3600Pa, highest air/water tightness rating
(4) Tandem Type (Next-Generation Ultra-High Efficiency)
1. Size: 2406×1156mm
2. Efficiency: 28.1% (lab prototype), theoretical 45% for 2-junction, 50% for 3-junction
IV. Future Competitive Landscape
1. From price competition to value competition
2. Long-term stability (field data)
3. Architectural harmony (aesthetics, customization)
4. Environmental recycling compliance
