Prosjekter

Tilhører gruppe for energimaterialer. Pågående forskning omfatter nye metoder for produksjon av elektrisitet fra varme og teoretisk analyse av avanserte solcelletyper (multibandceller og flerlagceller). Er også involvert i forskning på silisiumsolceller gjennom å være veileder eller medveileder på følgende doktorgradsprosjekter:

  • Charly Berthod, “Temperature coefficients of multicrystalline compensated silicon solar cells”: Prosjektet gikk ut på å undersøke hvordan ulike material- og celleparametre påvirker temperaturkoeffisientene til solceller laget av multikrystallinsk silisium. Charly Berthod disputerte i januar 2017.
  • Sissel Tind Søndergaard: Prosjekt som går ut på å forklare mekanismene som ligger bak funnene som ble gjort i Charly Berthods prosjekt. Her skal lignende celler studeres med metoder som gir mer informasjon. Eksempler på metoder er light beam induced current (LBIC), fotoluminescens (PL) og suns-Voc. Sissel Søndergaard disputerte i desember 2020.
  • Alfredo Garcia Sanchez: Er i gang med et prosjekt som går ut på å modellere egenskaper ved solceller matematisk. Alfredo disputerte i desember 2022.

 

Mye av silisiumforskningen har foregått i samarbeid med Elkem Solar.
