Problems solved by technology

[0004] Currently reported antimony sulfide solar cells mainly use organic compounds (such as P3HT, spiro-OMeTAD, PCPDTBT, PEDOT:PSS, etc.) The long-term stability of photovoltaic devices is seriously affected, and the photoelectric conversion efficiency drops rapidly, which largely restricts the development of its future industrialization.
