Electricity producing windows for greenhouses

On Wednesday, April 6th Wageningen UR Greenhouse Horticulture is organizing a workshop on electricity producing windows for greenhouses through Luminescent Solar Concentrators. The meeting will introduce the horticultural industry with the simplicity and flexibility of Luminescent solar concentrators (LSC) as a technology for the production of green electricity and the solar energy research community will be provided with insights and challenges associated with introducing new technologies in horticulture.

Generating renewable energy in a greenhouse without affecting its normal operation has long been desired by industry, researchers and policy makers. Attempts in the past proved to be unfeasible because it was too complex or ultimately too costly for market uptake. LSCs could change this situation completely. An LSC works regardless of its orientation resulting in a mechanically passive structure and it is the only known technique that can also concentrate diffuse light which allows it to function normally even in cloudy conditions. LSCs could therefore be incorporated as greenhouse covering in the future.

An LSC is nothing more than a fluorescent dye in a sheet of glass or plastic, 75% of the light re-emitted by the dye is internally reflected due to the higher refractive index of the plate, the trapped light will illuminate the edges where it can be transformed into electricity by conventional photovoltaic cells. In the illustration the intercepted light is in the visible range in order to visualize the mechanism, fluorescent dyes, however, intercepted light by the LSC could also be in the UV or infra-red range and transmit the photosynthetically active light for crop growth and development. Considering there is an equally wide variety of fluorescent dyes as there are plants grown in greenhouses it is easy to imagine an LSC that can be incorporated in greenhouses without affecting the crop growth underneath.

If you see future possibilities to facilitate the implementation of this technique or if you are simply interested to join the discussion, you are invited to participate in the workshop on Wednesday the 6th of April and join researchers from Wageningen UR, TU/e, TUDelft, UU and ECN in the discussion on a roadmap for Luminescent solar concentrators in greenhouses.

Program

The program will be divided into two parts. The morning program will provide an overview of the horticultural industry and will provide some insight into how light interacts with different crop types. During the afternoon the program will be aimed at luminescent solar concentrators and the latest insights into this technology.
