The group stated that the inherent radiation tolerance previously demonstrated at this length scale is sufficient to achieve new task types and lightweight and flexible appearances in harsh environments by reducing or eliminating the need for protective cover glass. However, the transmittance of ultra-thin absorbers is high, requiring integrated optical management to increase current.

The GaAs battery manufactured by the team only has an active layer of 80 nanometers (nm) thick, which increases to 120nm when adding a window and back field layer. The team used a patterning technique called displacement talbot lithography (DTL) to integrate the light management architecture onto the battery and compared its performance with other batteries that integrate a flat silver mirror to reflect light back into the battery. [DTL] is essentially suitable for wafer level, high-yield manufacturing, and therefore is a feasible method for manufacturing large-area photovoltaic devices with integrated light management, they explained.

These devices are described in the paper as ultra-thin GaAs solar cells with nano photonic metal dielectric diffraction gratings fabricated using displacement Talbot lithography, and are published in the progress of photovoltaics. The group was able to demonstrate an efficiency of 9.08% - a 68% improvement compared to using devices for processing on wafers.

Using simulations, the team further demonstrated that adding anti reflective coatings and further innovations to reduce surface shadows on the front grid can quickly increase this efficiency to 16%. They pointed out that although this type of device is unlikely to be useful for mainstream photovoltaic applications, they hope to open up new possibilities for space power generation and other potential applications. They concluded that these results indicate that future implementation plans for ultra-thin devices are unlikely to achieve current industry standard multi junction photovoltaic technology solely based on efficiency. However, the potential efficiency improvement of nanophoton integration demonstrated here, along with low quality and inherent radiation tolerance, may lead to new mission profiles and reduced emission costs.
