摘要： A new hybrid organic-inorganic structure of FTO/TiO2/Se/HTL/Au based selenium solar cell has been fabricated through a low-cost spin-coating process in air. In this process, selenium is completely dissolved in hydrazine, to form a homogeneous precursor solution. After spin-coating the precursor solution on the TiO2 substrates, following by sintering at 200℃ for 5min, a uniform selenium film with crystalline grains is formed. The selenium based solar cell exhibits an efficiency of 1.23% under AM1.5 illumination (100 mW·cm-2), short-circuit current density of 8 mA·cm-2, open-circuit voltage of 0.55 V, and fill factor of 0.37. Moreover, the device shows a stable ability with almost the same performance after 60 days.
