Scientists have determined that Spirulina platensis bio-layers act as effective optical filters to stabilize solar cells. The material prevents performance degradation in ambient temperatures that exceed 50 °C.
Why it matters
High temperatures typically reduce the efficiency of standard solar technology, threatening energy production in desert climates. This bio-layer solution offers a potential method for maintaining stability through infrared absorption.
Researchers identified an optical band gap of 2.34 eV for Spirulina platensis. Imaging revealed particle sizes ranging from 13 nm to 16 μm, with optical parameters extracted from UV-DRS measurements in the 250-680 nm range.
The details
The bio-layer functions by absorbing infrared radiation, which protects the solar cells from thermal stress. Researchers applied layers of varying thicknesses to test performance improvements using the Kubelka-Munk function and Kramers-Kronig relations.
