The growing market of connected machines and intelligent devices are becoming more and more important. These technologies are the origin of the development of the field of internet-of-things (IoT).
As a result, Indoor photovoltaics have attracted considerable interest thanks to their potential to power small and portable electronics devices.
Following this, the need of organic photovoltaic (OPV) devices are highly desirable for indoor applications because of their suitable characteristics of light weight, flexibility, and coloration.
In this context, high power conversion efficiency up to 20 % are already achieved with OPV module. further, excellent stability under indoor conditions have been obtained.
In terms of research on developing deposition techniques, Inkjet printing has attracted more and more attention as a printing electronic technology for large-scale printed flexible and stretchable electronics.
In fact, Inkjet printing has the advantage to provide freedom of forms and design on various substrates with low material usage comparing to other deposition techniques. This special characteristic has attracted a lot of attention of researchers on functional devices such as photovoltaic solar cells (PV).
However, inkjet printing still presents many challenges such as the stability of inks to avoid the nozzle clogging, the wetting behavior, compatibility of viscosity, surface tension with printheads.
So, herein, in this work, we present ITO-free all inkjet printed organic photovoltaic modules with high efficiency for indoor application with freedom of shape and design fabricated by Dracula Technologies company.
