The document models the operation temperature of c-Si PV modules through several steps: it calculates the light intensity absorbed in each module component spectrally from 300-2500 nm using ray tracing software; it solves a coupled system of semiconductor, thermal conduction, convection and radiation equations for the module temperature and power output; the simulations predict that PERC solar cells will have a 3.2°C lower operating temperature compared to full area Al BSF solar cells due to enhanced IR reflection in PERC cells.

1. Modeling operation temperature
of c-Si PV modules (Poster 4)
• The light intensity
absorbed in each
module component is
calculated spectrally
resolved from 300-2500
nm by ray tracing using
DAIDALOS
• A coupled system of
semiconductor, thermal
conduction, convection
and radiation equations is
solved for module
temperature and power
output
• Simulations predict:
3.2°C lower operation
temperature for PERC
compared to full area Al
BSF solar cells due to
enhanced IR reflection
PERC solar cells;
