Development of High-Efficiency Lightweight Space-Grade Silicon-Perovskite Tandem Solar Panels (150 W Class) for Small Satellites ( upto 200 kg Class)

Source

Source summary

Develop space-grade thin-silicon, perovskite and silicon-perovskite tandem cells plus a mandatory rigid 150 W panel for satellites up to the 200 kg class. A flexible roll-out panel is desirable. The source requires ground qualification to TRL 8, while a TRL 9 flight demonstration is optional, and sets targets of at least 22% AM0 efficiency at 28 C, 200 W per square metre areal power density, 80 W per kilogram specific power, radiation-tolerant encapsulation, thermal-vacuum operation from -120 C to 120 C and deployment demonstration.

EV charging Infrastructure – Solutions for easier and faster charging of EV batteries

Make EV battery charging easier and faster across two-, three- and four-wheelers. The source frames long waits with slow or moderate chargers as an adoption obstacle and asks for charging improvements rather than specifying a particular charger architecture.

Municipal Solid Waste Management

Improve municipal waste collection, segregation, transport and disposal, or turn that waste into biofuels, recyclable biological products and other commercially usable products. The challenge calls for cost-competitive outputs as well as better handling of an overloaded waste system.

E-waste Management

Improve e-waste collection, transport, processing and recycling, including recovery and reuse of valuable critical metals. The source frames discarded electrical and electronic equipment as both a disposal problem and a material resource; its historical rankings and recycling statistics are not current verification.
