Perovskite technology has shown impressive improvement in the last decade. Here, the first GPS-perovskite-powered application is showcased by integrating flexible perovskite modules (fPSMs) onto an animal tracking collar for powering the IoT device that monitors wildlife bison to preserve the species and its habitat. A prototype of a solar-powered collar was designed to be more optimal for monitoring ample wildlife than commercially available asset-tracking devices, so it can provide necessary data to successfully introduce bison to new habitats. The fPSM were fabricated on a plastic substrate and connected in series configuration to generate power of 400 mW. A robust packaging with polycarbonate sheets and mechanical rivets was realized to withstand harsh environmental conditions, validated by conducting scratch and bending tests. The electronics and software system were optimized for ultra-low power mode operation, consuming only 1.9 mWh, which is 200 times less than the energy generated by our modules. The packaged modules in the outdoor testing setup retained over 30 % of their initial PCE and power after 350 days (8400 hours), giving still 60 times more power than necessary over ~1 year of operational condition.

Perovskite technology has been advancing at unprecedented levels in the last years, with efficiencies reaching up to 25.7%. State of art results are obtained on a very small area scale (<0.1cm2), by adopting high materials wasting processes not compatible with industry and with market exploitation. Silicon is a well-established technology and one of the advantages of Perovskite is its ability to pair with Silicon forming a tandem device that extracts charges reducing transmission and thermalization losses. In this work, we focus on finding a strategy to fabricate 15.2x15.2 cm2 Perovskite modules by avoiding any spin coating deposition and by adopting a green solvent cleaning step. Furthermore, we optimize the ITO top electrode deposition by adjusting sputtering process and buffer layer deposition; finally, we focused on light management by applying an antireflective coating. We obtained a semi-transparent and a tandem Silicon-Perovskite module in 4T configuration on 225cm2 (4T configuration) with 13.18% and 20.99% efficiency, respectively, passing ISOS-L1 (under continuous light soaking in air) test with a remarkable T80 of 1459hÂ
