本研究探討以五環素(pentacene)/駢苯衍生物(perylene derivatives, PTCDI)異質接面太陽能電池之特性,利用pentacene作為電子施體有機材料,PTCDI -2C~13C作為電子受體有機材料,製作出異質接面為pentacene/ PTCDI-2C ~13C等12種有機太陽能電池,比較不同碳數的駢苯衍生物對於有機太陽能電池之光電轉換效率之影響。
在AM1.5G、100 mW/cm2的模擬太陽光下,以pentacene/PTCDI-7C異質接面太陽能電池具有短路電流9.882 mA/cm2、開路電壓0.376 V、填充因數0.523及光電轉換效率達1.945%,皆比其他pentacene/PTCDI-2C ~13C異質接面太陽能電池來的大。由薄膜分析可知PTCDI-7C在這12種太陽能電池中具有較低的電子電洞復合發光效率,可以讓較多激子(exciton)到達異質接面進行電荷分離,減少電子電洞對復合發光的機率;此外,由光激發螢光光譜之峰值位移(peak shift)配合原子力顯微鏡表面結構圖,可以得知當PTCDI-7C成長在pentacene上時會順著pentacene的結構成長薄膜,故較無缺陷產生在P/N接面處;而在其他結構下則無此現象產生,致使在pentacene/PTCDI-7C薄膜中的載子有較大的機會可以移動至電極,使光電流提高,進而使光電轉換效率提高。
The characteristics of pentacene/perylene derivatives based organic solar cells are investigated in this thesis. Donor and acceptor layers are pentacene and N,N'-dioctyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-2~13C), respectively. Twelve organic solar cells with pentacene/PTCDI-2~13C heterojunctions were fabricated to study the influence of various alkylic perylene derivatives on the power conversion efficiency.
Under the sunlight simulator with AM1.5G filter and 100 mW/cm2, the solar cell of pentacene/PTCDI-7C heterojunction with cathode of Ag/Al bilayer has the best performance among the devices with pentacene/PTCDI-2~13C heterojunctions. In PL spectrum analyses, the pentacene/PTCDI-7C film had lower recombination rate than the other pentacene/PTCDI-2~13C films; therefore, more excitons could reach the P/N junction and enhance short-circuit current. Furthermore, the PTCDI-7C film grown on the surface of penatcene was more matched than other PTCDI films analyzed by the PL peak shifts of 10 nm and 45 nm thick PTCDI-2~13C and images of atomic force microscope. More lattice match between the films of pentacene and PTCDI resulted in fewer defects in P/N junction and more carries can reach electrodes. Accordingly, the power conversion efficiency approach 2% was obtained from the solar cell with the active layer of pentacene/PTCDI-7C.
