Perovskite Solar ‘Stickers’ Are Almost Here: How Flexible Laminates Could Turn Walls, Cars & Roofs into Power Plants

A flexible perovskite module with WVTR ≈ 5.0 × 10⁻³ g/m²/day retained 84% of its power after 2,000 hours at 85°C/85% RH. Japan is subsidizing Sekisui Chemical to build a 100 MW film-type perovskite plant by 2027. A Chinese startup unveiled a 1.2 m × 1.6 m flexible module rated 260–300 W and weighing 2.04 kg. Several manufacturers have passed IEC reliability tests for flexible perovskite modules.

Metal-Organic Frameworks (MOFs): Sponge-Like Crystals Poised to Transform Carbon Capture, Clean Energy and More

MOFs reach internal surface areas up to 7,000 m²/g, with nearly 90,000 structures created in two decades. CALF-20 captures about one ton of CO2 per day per cubic meter; ZnH-MFU-4l binds over 90% of CO2 from hot flue gas. MOF-303 enabled water harvesting in Death Valley, delivering up to 285 grams per kilogram daily. The EU MOST-H2 project screened 10,000 MOFs for hydrogen storage by 2025.

  • CAR vs SOL Shares: Value Comparison for 2026
    May 22, 2026, 10:39 PM EDT.

The company operates vehicle marketplaces globally, including Australia and the US. In contrast, Washington H Soul Pattinson (ASX:SOL) shares are near a 52-week high, reflecting its status as a diversified investment holding with low debt (8.5% debt-to-equity) and a consistent dividend history dating back to 1903.

Investors seeking growth might favour CAR's expanding profits and market presence, while income-focused investors could prefer SOL's stable dividends and lower risk profile.
