制备了ITO/MoO3(6nm)/Rubrene(30 nm)/C70(30 nm)/BCP(6nm)/Al(150 nm)的PN结构和 ITO/MoO3(5nm)/Rubrene(25 nm)/Rubrene:C70(5nm)/C70(25 nm)/BCP(6n m)/Al(150 nm)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/C70 OSCs的性能。 |

Organic solar cells (OSCs) are considered to be a new generation of phot ovoltaic 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(6nm)/rubrene(30nm)/C70(30nm)/ BCP(6nm)/Al(150nm) and PIN cells with the structure of ITO/MoO3(5nm)/rubrene(30nm)/rubrene:C70(5nm)/C70(30nm)/BCP(6nm)/Al(150nm) were fabricated.The effect of heat treatment on the performance of two cells is researched by thermal annealing.The experimental results indicate that the shor t-circuit current is up to 3.526mA·cm-2(PN) and 5.413mA·cm-2 (PIN),and the power conver sion 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 e fficiencies of PN/PIN cells are enhanced by 19.0%,7.1%,28.3% (PN) and 4.8%,20%,24.1% (PIN),respectively.Experime ntal results show that the heat treatment can improve the performance of rubrene/C70 based OSCs. |
