Transparent perovskite PV project connected to grid in China

Reports suggest that a solar power project in China, which utilizes translucent perovskite panels, has recently been connected to the grid in Gansu Province. This project was developed through a collaboration between the Electric Power Science Research Institute of the China State Grid Gansu Electric Power Company and a renewable energy subsidiary of China Datang Corp.

It was stated that the perovskite solar cells were processed to be translucent by the application of special graphical structures, including grind lines and dots, on the perovskite film. The specific structures are the result of precise control of parameters, including exposure time and depth. The graphical structures allow for the optimization of the light propagation path within the cell, thereby enhancing light absorption efficiency and improving the cell’s photoelectric conversion performance.

 

The start of operations for the solar project marks a major achievement for the research team. In contrast to the ideal conditions observed in laboratory settings, the outdoor environment is inherently complex and variable, which presents a challenge for researchers. A number of factors, including light intensity, temperature, humidity, wind speed and dust accumulation, have the potential to impact the performance of solar cells. 

Once the project is connected to the grid, the team will undertake a verification process to assess the performance of the semi-transparent perovskite solar cells. Furthermore, the team will gain a comprehensive understanding of the advantages and limitations of the cells in practical applications by examining their photoelectric conversion efficiency, stability, durability, and adaptability to extreme climatic conditions.
