Journal ArticleDOI
Sodium doping of solution-processed amine-thiol based CIGS solar cells by thermal evaporation of NaCl
Soňa Uličná,Liam M. Welch,Ali Abbas,Mustafa Togay,Vincent Tsai,Thomas R. Betts,Andrei V. Malkov,John M. Walls,Jake W. Bowers +8 more
TL;DR: In this article, thermal evaporation of a thin layer of NaCl prior to selenisation resulted in absorbers with significantly larger CIGS grains than previously seen with Na diffusing directly from the from soda-lime glass substrate.
Journal ArticleDOI
Water based spray pyrolysis of metal-oxide solutions for Cu2ZnSn(S,Se)4 solar cells using low toxicity amine/thiol complexants
Lewis D. Wright,Jamie C. Lowe,Martin Bliss,Vincent Tsai,Mustafa Togay,Thomas R. Betts,John M. Walls,Andrei V. Malkov,Jake W. Bowers +8 more
TL;DR: In this paper, a less harmful amine-thiol pairing and water as a diluting solvent were employed to reduce the toxicity of hydrazine-based solution for spin-coated Cu2ZnSnS(S,Se)4 cells.
Combined electrical and optical characterisation of recombination mechanisms and minority carrier lifetime in solar cells
Vincent Tsai,Francesco Bittau,Christos Potamialis,Martin Bliss,Thomas R. Betts,Ralph Gottschalg +5 more
TL;DR: In this paper, a measurement system which combines optical and electrical characterisation of carrier lifetime and recombination mechanisms of thin-film solar cells is presented, which combines spectrally resolved photoluminescence (PL), time-resolved photoline (TRPL), and transient photocurrent (TPCD), which are measured using a single excitation laser source at the same spot of the solar cell.
Proceedings ArticleDOI
Electronic properties of solution-processed Cu(In,Ga)(S,Se)2 solar cells using metal chalcogenides and amine-thiol solvent mixtures
Soa Uliena,Mustafa Togay,Martin Bliss,Vincent Tsai,Lewis D. Wright,Jamie C. Lowe,Andrei V. Malkov,John M. Walls,Jake W. Bowers +8 more
TL;DR: In this paper, the effects of post-deposition air-annealing on the electronic properties of solution-processed heterojunction CIGS solar cells were examined through capacitance-voltage profiling and admittance spectroscopy.
Proceedings ArticleDOI
Quantifying minority carrier lifetime and collection efficiency of solar cells by combined optical and electrical characterisation techniques
TL;DR: In this article, a combined measurement system for spectrally-resolved photoluminescence (PL), time-Resolved photoline (TRPL), and transient photocurrent decay (TPCD) measurements is presented to characterize the physical properties of solar cells and their materials.
