Adding Free-Carrier Absorption in SunSolve

There are two types of optical absorption in a semiconductor: band-to-band absorption (which can contribute to light generated current) and free-carrier absorption (which does not contribute to current generation and thus represents a loss mechanism).

This video provides an overview of how to use the free-carrier absorption (FCA) feature within SunSolve.

The video covers

• Adding FCA to films and thick slabs
• Different models available and setting the inputs
• Adding and substracting FCA from a material
• Viewing the total, generated and free-carrier absorption in the output
• Impact on exported generation profiles
• Impact on generation of electrical current within SunSolve
