Donor/acceptor heterojunction organic solar cells
2017
Organic solar cells (OSCs) have made very good improvements in recent years, reaching power conversion efficiencies above 10% [1]. This have been achieved through chemical synthesis of new organic materials with improved properties and also by new and more or less complex structures such as donor/acceptor (D/A) or bulk heterojunction OSCs. Here we report the results of initial development of OSCs based on the simple D/A heterojunction [2]. Copper phtalocyanine (CuPc) is used as donor organic material, whereas perylenetetracarboxylic dianhydride (PTCDA) and fullerene (C60) as acceptor organic materials. Moreover bathocuproine (BCP) is used as exciton blocking layer. Devices are fabricated by…
Blue Emitting Organic Light Emitting Diodes
2019
Organic light emitting diodes (OLEDs) [1] can be fabricated on a range of materials such as glass, silicon or flexible plastic substrates. This can be exploited for the realization of integrated OLED-based fluorescence chemical sensors [2] and microfluidic systems [3] for application in areas such as biotechnology, life sciences, pharmaceuticals, public health and defense. These devices hold promises to be cost effective, ultra-compact (including the possibility to be fabricated into large bidimensional arrays), and capable to handle smaller sample volumes in order to achieve high throughput. Blue light is advantageous because it is strongly absorbed by most sensing molecules attached to bi…
