Types of photovoltaic power generation systems

As distributed photovoltaics become increasingly prevalent in thousands of households, the demands for photovoltaic solutions are becoming more diverse. The conventional on- grid system, where photovoltaic power generation is primarily for self-use, is no longer the sole option. Depending on the specific requirements of different scenarios, photovoltaic power generation systems can be categorized into five …

Chinese institute unveils 26.1%-efficient perovskite PV cell with new additive

The Chinese Academy of Sciences said this week that its researchers have fabricated homogenized perovskite films that could increase the efficiency and stability of perovskite solar cells. The scientists said they addressed the typical phase segregation issue that inevitably takes place inside perovskite films and affects both the power conversion efficiency and thermal stability of perovskite PV devices. This …
