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 manage custom data sets within SunSolve-Power. Custom data sets can be entered for the refractive index of a material, the reflection and transmission of an interface, the spectrum of incident light, and the collection efficiency of a layer.
This video provides an overview of the changes to SunSolve-Power introduced in version 6.19
This video provides an overview of the electrical solving engine, how it links to the optical solver and demonstrates the basics of setting the inputs within the user interface, running a simulation and looking at the output.
This video provides a basic introduction to the optical solving methods and concepts used in the SunSolve software.
This video provides an overview of the optical solving engine and demonstrates the basics of setting the optical inputs within the user interface, running a simulation and looking at the output.
This video explains how to use the full module simulation feature including: defining module frames, exploring mismatch losses, estimating bifaciality
This video explains how to use the system simulation features. It is a continuation from "Solving PV Modules with SunSolve" and some knowledge from that video is assumed
This video is aimed at SunSolve version 4 users who have migrated to version 5
In 2018, Dr Keith McIntosh presented a simulation workshop at SNEC with attendees from leading cell and module manufacturing companies. The slides and audio are presented in the video below.
