Abstract
The project Renewable and green energy smart power supply systems for on-body sensors and handheld devices exhibits as main goal the development of new and innovative charging systems able to support the work of on body sensors and handheld devices. The target energy supply sources are Organic Solar Cells fabricated in the inverted cells technology which provides more robust and friendlier to manipulate devices. Many of the donors and acceptors envisaged to be used are compounds which were already obtained and investigated in our group (in usual OSCs). The target inverted OSCs use as support light and flexible materials which at the same time are eco-friendly and biocompatible. These materials are appropriate to the proposed applications, being possible their “quite” invisible attachment to clothes or small equipment’s and the total requested active surface is of few cm2. Besides the original work concerning the access to the OSCs which transform light in electric power a complex and original arsenal of miniature electronic devices must be produced in order to ensure the appropriate work of the entire power supply device. Several cells will be smartly connected in an OSC Array (able to provide current at a given voltage). The output current obtained in the OSC Array will be modulated by a Charger System which will produce a current in appropriate parameters either for the charging of Li-ion or Li-po batteries which deserve a handheld device or for the charging of a supercapacitor (with role of battery) which deserve an on-body sensor. Another important device is the DC-DC convertor with role to modulate the current sent to the on-body sensor. All these electronic circuits will use microelectronics design and will be implemented on a thin flexible film coated with ITO as a PCB (printed circuit board) substrate. At the end of the project we will provide demonstrators to prove the viability of our work and we will record an evolution from TRL2 to TRL4.

Objectives
The goal of our project is to develop new charging systems for the batteries used on body sensors and handheld devices. The target charging systems are projected to use renewable and green energy sources and are developed on the basis of organic solar cells (OSC) employing the model with Donor/Acceptor (D/A) molecular materials with tailored properties.
Starting from the main goal of the project and considering the components and the functional scheme of the demonstrators the following specific objectives were considered:
O1 Access to inverted OSC with suitable properties for the fabrication of target power supply devices
O2 Access to the electric and electronic components of target power supply devices
O3 Fabrication and testing of target power supply devices
O4 Access to improved power supply devices (based on research feed-back) and fabrication and testing of the demonstrators
O5 Improvement of professional level of the members of the team and of the academic and research environment, intellectual protection of the research results
These objectives are based on the know-how of the two teams and relies the experience of the UBB group in the field of OSCs and organic synthesis and optoelectronic characterization of compounds and devices with the high experience of the group of UT Cluj-Napoca in the field of developing microelectronic devices for different applications as sensors and power supply devices. The competences of the two teams, their complementarities, their back grounds in the requested domains for the development of the project represent a solid base for the success of the proposed research. The feasibility of the project is supported also by the manner in which all the steps and the components were projected. For each step there are several solutions (e.g. different donors, acceptors, flexible and light supports, different schemes for microelectronic components), the development of the project is based on a powerful feed-back scheme which allows a rapid answer and modifications of the devices in order to improve their work.
Concerning the feasibility of the project we underline a) the research teams are complementary and with important achievements in their fields; b) the objectives are clear and there are several alternatives to touch them; c) the research plan is well organized and the target tasks are clear. The previous scientific achievements of the two partners are the main arguments sustaining a TRL 2 value at the beginning of the project. The previous achievements of the partners are published in a significant number of papers (listed in the section devoted to bibliography) published in highly ranked journals. The project coordinator (UBB) has been involved until now in research activities related to the design, synthesis and characterization of different molecular systems with donor properties including systems based on triarylamine, small molecules obtained by simple and clean synthesis, and molecular donors prepared by metal-free synthesis, etc. The previous results of the partner UT Cluj-Napoca focus on the conception and fabrication of original and innovative microelectronic devices for many applications in sensors and power supply systems. On the basis of the previous experience and of a solid documentation the concepts and the working plan for this project are clearly formulated and the technological requirements are well identified.
The final aim of the project is to attend the TRL 4 level by developing demonstrator models where the basic technological components are integrated and all the pieces will work together. The assessment of the functionality of the integrated system will be carried out in laboratory environment. The feasibility of the project supports the access at the end of the project to the TRL 4 level.
