Mini Solar (Wait-list only)

Current project

The 2021 Mini Solar VIP team is now full.

You can join the Wait-list in case a position on the team becomes available

VIP Snapshot

Bigger isn’t always better, so we’re pushing the boundaries of solar energy to power small devices, like medical implants and IoT sensors, with a sustainable source of energy. 


VIP ChallENG research goals

This project aims to design and create millimetre-sized solar energy harvesting devices that can provide continuous power for medical implants and IoT sensors. Specifically, we plan to:  

  • Design and prototype silicon photovoltaic devices capable of charging a small lithium ion battery 
  • Design and prototype mini lithium ion battery cells that can be fabricated on a silicon wafer 
  • Demonstrate mini-solar harvesting power systems integrated with low-power electrical circuits (e.g., for implants or IoT sensors)  
  • Develop computational models of hybrid devices  
  • Identify new device designs, sensor distribution methods and applications 

Research, design or technical ChallENG

  • Design and make small silicon photovoltaic devices that can charge a mini battery and be integrated on an integrated circuit for ultra-miniaturisation
  • Design and make mini lithium ion battery cells that have a high energy density  
  • Demonstrate prototype implants or sensors 
  • Design of solar energy harvesting devices for particular operating environments (e.g., under the skin, in the field) 
  • Assess the durability of solar energy harvesting devices in diverse environments 
  • Ideation
