Personal Research
1.Organic Photovoltaic, OPV2014年我們利用2,3-pyridinediol為添加劑添加於有機太陽能電池(OPV)中的 P3HT:PCBM主動層溶液中,可以改善主動層的表面形態使其各自形成30 nm的雙連續網狀,如圖一(a)和(b),而30 nm的區塊大小是與OPV電子擴散路徑相當。另外我們也利用ESCA來分析垂直於載體方向的元素變化,如圖二(a)和(b),加入添加劑後主動層表面的PCBM分布量會大於底層而P3HT則會傾向分布於主動層底層,這樣的分布是有利於電子與電洞傳遞電極,因此光電流會從8.5增加至10.6 mA/cm2,效率也可從3.5增加到4.4%,此外此添加劑也可以應用於不同系統中,如P3HT:ICBA(效率可從3.35增加至5.93%)及PTB7:PCBM(效率可從5.46增加至7.54%),並且可以省去主動層額外熱處理的步驟。
2.Perovskite Solar Cells
2014年我們提出利用兩步驟旋塗法來控制鈣鈦礦膜結晶的速度,先於ITO/PEDOT:PSS上均勻塗佈PbI2薄膜,接著在塗佈適量濃度和體積的甲基胺碘溶液(MAI)來合成高品質鈣鈦礦膜。兩步驟合成法可以有效地降低鈣鈦礦膜結晶的速度,最主要的原因是碘化鉛和甲基胺碘一開始只會在界面(2D)產生反應,隨後再以擴散的方式進行反應生成鈣鈦礦,大大降低了同步(3D)結晶的機會,因此可以有效地控制鈣鈦礦結晶的速度,獲得較緻密且連續的薄膜。將高品質鈣鈦礦膜搭配高載子移動率PC71BM為電子傳遞層,元件製備如圖三,所得的鈣鈦礦太陽能電池效率可以達到16.31%如圖四(a),而元件也無遲滯效應(photocurrent hysteresis) 如圖四(b)。
2015年我們提出利用無毒性的水作為添加劑來製作高品質的鈣鈦礦膜,透過添加劑劑量的控制,不但可以增加鈣鈦礦膜的結晶度和晶粒大小外圖五(a),還可增加元件的長時間效率穩定性,最終獲得元件Jsc= 20.6 mA/cm2, Voc= 1.03V, FF= 0.85, E= 18%的高光電轉換效率。此填充因子及效率,皆為當時反式鈣鈦礦太陽能電池的最高值圖五(b)。
