摘要
制备了ITO/MoO3(6nm)/Rubrene(30nm)/C70(30nm)/BCP(6nm)/Al(150nm)的PN结构和ITO/MoO3(5nm)/Rubrene(25nm)/Rubrene:C70(5nm)/C70(25nm)/BCP(6nm)/Al(150nm)的PIN结构有机太阳能电池(OSCs)。通过对两种器件进行热处理,研究热处理对OSCs性能的影响。实验表明,在热处理后,PN结构和PIN结构器件的短路电流密度分别达到了3.526mA·cm-2和5.413mA·cm-2,功率转换效率分别达到了1.43%和2.09%。与未经过热处理的器件相比,PN结构和PIN结构器件的短路电流密度、填充因子、功率转换效率分别提高了19.0%、7.1%、28.3%和4.8%、20%、24.1%。可见,热处理可以提高Rubrene/C70OSCs的性能。
Organic solar cells （OSCs） are considered to be a new generation of photovoltaic devices due to many advantages,such as low cost, compatibility with flexible substrates and ease of processing. The small molecule organic material like rubrene is widely used in organic light emitting diode （OLED）. In this article,PN cells with the structure of ITO/MoO3 （6 nm）/rubrene（30 nm）/C70 （30 nm）/BCP（6 nm）/Al（150 nm） and PIN cells with the structure of ITO/MoO3 （5 nm）/rubrene（30 nm）/rubrene..C70 （5 nm）/C70 （30 nm）/BCP（6 nm）/Al（150 nm） were fabricated. The effect of heat treatment on the per- formance of two cells is researched by thermal annealing. The experimental results indicate that the short-circuit current is up to 3. 526 mA · cm-2（PN） and 5. 413 mA · cm-2（PIN） ,and the power conversion efficiencies of these cells are as high as 1.43% （PN） and 2. 09% （PIN） with heat treatment,respectively. Contrast with the devices without heat treatment, short-circuit current, filling factor and the power conversion efficiencies of PN/PIN cells are enhanced by 19.0K, 7. 1% ,28. 3% （PINT） and 4.8%, 20 %, 24. 1% （PIN）, respectively. Experimental results show that the heat treatment can improve the performance of rubrene/CT0 based OSCs.
