Enhancing the efficiency of solar cells with bio-based material from algae – step 2

This project aims to in detail study how to create formulations to reach homogeneous coatings of diatom frustules on solar cells and solar panels to increase the efficiency of converting solar energy into electrical energy.

This will be performed in collaboration with academic experts on surface chemistry (Chalmers) complemented by applied knowledge on industrial coatings and formulation techniques from suppliers of coatings to the solar industry that Swedish Algae Factory already have collaborations with. The optimized coatings will be coated on silicon solar cells and solar panels and the efficiency will be tested by an independent testing institute (Institutt for Energitekknik, IFE, Norway) in collaboration with an expert on solar energy (Lundahl Solar Consulting).

The coating formulation will also be evaluated in collaboration with a Swedish producer of thin film coatings, Midsummer, who are also a partner in the consortium. The coating development above will also be complemented by work on deeper understanding of how the optical properties of the frustules effect solar cells and solar panels in collaboration with an ongoing project financed by the Swedish Research Council (Wulff VR-2018-04289) that aims to map out the optical properties of frustules.
