中文摘要 鈣鈦礦太陽能電池已經成為太陽能電池的新寵兒,歸因於極高的光電 轉換效率,吸引全世界的研究團隊爭相研究,從 2009 年的 3.8 %由日本 Miyasaka 團隊首先將 CH3NH3PbI3 鈣鈦礦材料用於染料敏化太陽能電池 結構中,用鈣鈦礦材料取代原先用於光電轉換的小分子染料,並搭配二 氧化鈦及液態電解液質,至 2014 年由韓國研究團隊 KRICT 將鈣鈦礦太陽 能電池光電轉換效率提升到 20 %,發展的程度已經超越其他的薄膜太陽 能電池,如此高的光電轉換效率因鈣鈦礦獨特的光電特性,包含長的載 子擴散長度,有適合的能帶,高的吸收係數,優異的載子遷移率,我們以兩步旋轉塗佈法製作出結構為 ITO/PEDOT:PSS/Perovskite/PC61BM/BCP/Al 有機型鈣鈦礦太陽能電池,得到開路電壓為0.79 V,短路電流密度為19.73 mA/cm2,填充因子為56.32 %,光電轉換效率為8.77 % ,並研究水與鹵化鉀摻雜於PbI2前驅層對於效率之影響,實驗結果為當摻雜濃度為2vol%水及4mg/ml的碘化鉀時得開路電壓為0.97 V,短路電流密度為21.34 mA/cm2,填充因子為66.97 %,光電轉換效率為13.86 %提升了近58 %。
英文摘要 In 2009, Miyasaka et al. used CH3NH3PbI3 to replace organic dyes in
dye-sensitized solar cells (DSSCs) for the first, where the mesoporous
titanium oxide (TiO2) and a liquid electrolyte were used. Power conversion
efficiency (PCE) of 3.8 % was achieved. Power conversion efficiency (PCE)
close to 20 % has been achieved in both mesoporous structure devices as
well as photovoltaic heterojunction (PHJ) devices. The highest certified
efficiency has reached 20.1 % (non-stabilized) by the KRICT in late 2014. It
took less than five years for PCE of perovskite solar cells to increase from 3.8
% to above 20 %, while it takes several decades for other kinds of inorganic
solar cells to achieve this and most photovoltaic materials never reach 20 %
efficiency. The perovskite solar cells has attracted tremendous research
attention due to its unique optical properties such as long carrier diffusion
lengths, appropriate energy gap, high absorption coefficients , excellent
carrier mobility. We successfully demonstrated that the organic based
perovskite solar cell whose structure is ITO/PEDOT:PSS/Perovskite/PC61BM/BCP/Al gave a Voc of 0.79 V, a Jsc of 19.73 mA/cm2, a FF of 56.32 %, a PCE of 8.77 % via two-step spin coating process. After fabricating the devices in stable process, we started to study on doping H2O and potassium halide in PbI2 precursor layer. We got the device gave a Voc of 0.97 V, a Jsc of 21.34 mA/cm2, a FF of 66.97 %, a PCE of 13.86 % by doping 2vol% H2O and 4mg/ml KI in PbI2 precursor layer. The power conversion efficiency (PCE) has increased about 58 % after doping 2vol% H2O and 4mg/ml KI in PbI2 precursor layer.
