Then, the state-of-the-art progress for photothermal conversions of solar energy is introduced in detail, mainly including photothermal water evaporation and desalination, photothermal catalysis, photothermal electric power generation, photothermal bacterial killing, photothermal sensors, and photothermal deicing.
To meet the demands of the global energy transition, photothermal phase change energy storage materials have emerged as an innovative solution. These materials, utilizing various photothermal conversion carriers, can passively store energy and respond to changes in light exposure, thereby enhancing the efficiency of energy systems.
Although photothermal electric power generation can show a solar-to-electricity conversion efficiency exceeding 7% under 38 Sun, its conversion efficiency remains very low under low concentration solar intensity, such as 1 Sun or ambient conditions.
Solar to hydrogen-electricity and thermal storage system (STHET) is proposed. Hydrogen production in STHET is improved by recycling scattered light. Low-grade waste heat is converted into electrical energy by flexible TEGs. STHET can achieve continuous power generation by self-thermal storage capability.
(53) Making the most use of solar energy along the photothermal evaporation process can contribute in addressing the energy and water scarcities. Researchers have developed strategies to further harvest the input solar energy by generating electricity during the processes of solar absorption, vapor generation, and water condensation.
Among all the solar energy conversion technologies, photothermal conversion of solar energy exhibits unique advantages when applied for water purification, desalination, high-temperature heterogeneous catalysis, anti-bacterial treatments, and deicing.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
