Next Generation Indoor Light Harvesting: Wireless power for Wireless IoT Sensors

Periodic Reporting for period 1 - Epishine LEH (Next Generation Indoor Light Harvesting: Wireless power for Wireless IoT Sensors)

Reporting period: 2019-08-01 to 2020-07-31

The increasing digitization of society is one of the most interesting frontiers on the horizon to increase economic growth, curb emissions and improve general quality of life. One key part of the digitalization is the mass implementation of sensor network to gather data; data which can be used optimize ventilation, lighting etc. As the market for these sensor is expected to grow rapidly over the coming decade, powering these devices will be a severe bottleneck. The current available solutions: wiring or primary batteries are either expensive or require extensive maintenance and contain environmental challenging materials.
In this project we seek to address the shortcomings of the current available powering solutions by developing a light energy harvesting solution suitable for building and home automation with the overall aim to bolster the rising adoption of wireless sensor networks.
Our light harvesting solution is based on a novel and proprietary process of producing printed organic light modules which enables the production of an light energy harvesting product with a very good low light performance, excellent material integration properties and a minimal carbon footprint.
Epishine has, since the onset of the project continued to improve our existing processing abilities and further the market acceptance of this technology.
Work on investigating existing as well as novel materials has increased the performance and lifetime for both - current generation of products as well as next generation products. By finetuning our core process know-how, standardizing work tasks and procurement of new machinery the production capacity, yield and overall quality of, has improved significantly.
We have worked intensively with several commercial partners to create a common understanding of how the market needs and the possibilities our technology can meet. This market interaction within our customers’ projects has also accelerated the transition of a developing perspective to a product perspective where we have created have yielded a number of integration solutions, prototypes and evaluation kits ready to be tested in a real life environment. We have also focused our activities on revising and executing our marketing and commercialization plans, including building sales channels and approaches, exploring protection of current and emerging IP and licensing for future expansion.
Epishine distinguishes itself by producing the world’s first, and currently only commercially available, fully organic and printable PV material. Our material occupies a unique position: providing high Performance (indoor power efficiency at low light), good Compatibility with IoT device form factors, good Reliability/Lifetime, and good Sustainability (using all-organic components). The low resource usage and print production method results in excellent Production scalability and low cost/high Affordability During the course of the project, we have identified several key areas to enable the full commercial implementation of the very first light energy harvesting solution; electronic integration, productization and supply of production quality modules. Within the area of electronics we have found ways to integrate management, temporary energy storage and the light harvesting modules in a fashion which have gained market acceptance. One outcome of this are the Evaluation kits which can be sent out to prospective customers.

To facilitate market interaction the full productization of our modules has been necessary which includes the transfer from a developing prototype to a product with set specifications regarding performance, size etc.
To be able to supply the customer projects (and beyond) with production level quality modules the production process has been further developed and we can satisfy our customer needs. Boosted by a 3 M€ equity round we will be able to scale both production and sales to reach market introduction.
