Compared with conventional air-processed OSCs, this strategy remarkably increases the cell power conversion efficiency (PCE) from 16.7% to 19.3% (independently certified as 19.2%), representing the top value of air-processed OSCs.
The optimal thermal performance of the system occurs on day 219, when the energy storage density, the exergy efficiency and the converted electrical efficiency of the system are 9.97 kWh/m3, 69.41 % and 72.09 %, respectively. In the summer months, when light conditions are better, the system shows better thermal and economic performance.
Current high-efficiency organic solar cells (OSCs) are generally fabricated in an inert atmosphere that limits their real-world scalable manufacturing, while the efficiencies of air-processed OSCs lag far behind. The impacts of ambient factors on solar cell fabrication remain unclear.
Compressed air energy storage (CAES) technology stands out among various energy storage technologies due to a series of advantages such as long lifespan, large energy storage capacity, and minimal environmental impact .
The design exergy efficiency and NPV of the system are 66.99 % and 12.25 M$. Compressed air energy storage (CAES) is one of the important means to solve the instability of power generation in renewable energy systems.
By combining optical modeling and experimental results, a full optical analysis is provided for the STOSCs with details on photon harvesting, optical losses, transmission properties, energy distribution spectrum, electric field intensity distribution, and photon absorption rate distribution within the devices.
