- One Circuit to Understand a Solar Cell: The Single-Diode ModelA current source, a diode and two resistors explain every change on an I-V curve. In eight figures we show what Rs, Rsh, I0 and n each control, and how to work back from a curve''s shape to the underlying problem.
- 2026 Failure Ranking of Eight PV Module BOM Materials: What Is Holding Reliability Back?There is no public, authoritative ranking of complaint rates for module BOM materials, but the 2026 Kiwa PVEL Scorecard and its September follow-up analysis provide solid substitute data. Drawing also on IEA PVPS, kWh Analytics and UNSW research, we rank glass, encapsulant, junction box, frame, sealant and potting, ribbon and flux, silver paste and backsheet by failure risk and review each one.
