  1. Degradation of Ge subcells by thermal load during the growth of multijunction solar cells

    • During the growth of Ge-based multijunction solar cells, the Ge subcell suffers performance degradation.
    • In lattice-matched GaInP/GaInAs/Ge multijunction solar cells, we observed a 20% and a 24% relative loss in JSC and VOC, respectively, together with a significant change in both the emitter depth and doping profile.
    • According to our numerical simulation, the QE degradation and VOC drop are mainly attributed to extremely poor minority carrier properties at the gradual emitter zone acting as an almost dead layer.

    This work explores the fabrication of Cu2ZnSnSe4 solar cells on polyimide and on soda-lime glass at temperatures below 500°C. A 4.9% efficiency solar cell is achieved setting a record for a kesterite device fabricated on a polymer substrate. However, working at low temperature promotes the formation of SnSe2 both on glass and on polyimide. This secondary phase is found to be strongly related to process temperature and to be detrimental for the devices by creating shunting paths.

  3. Outdoor photoluminescence imaging of photovoltaic modules with sunlight excitation

    High resolution outdoor photoluminescence image of photovoltaic module was obtained under full sunlight using contactless modulation method (Figure A) that can identify various defects that lead to power loss. This image was compared to the indoor electroluminescence image (Figure B). The contactless luminescence modulation is achieved by periodically changing the optical generation rate of at least one cell within the module, which in turn changes the biasing condition of all other cells that are connected to the same bypass diode.

  4. Spectral binning for energy production calculations and multijunction solar cell design

    Currently, most solar cells are designed for and evaluated under standard spectra intended to represent typical spectral conditions. However, no single spectrum can capture the spectral variability needed for annual energy production calculations, and this shortcoming becomes more significant for series-connected multijunction cells as the number of junctions increases. Here, we show how a large spectral set can be reduced to just a few “proxy” spectra, which still retain the spectral variability information needed for annual energy production design and evaluation.

    Minimising bulk lifetime degradation during the processing of interdigitated back contact silicon solar cells

    A key factor in pushing performances of interdigitated back contact solar cells lies in the quality of the bulk material and mitigating process-induced degradation. Our results show that a preoxidation treatment of n-type float zone wafers can lead to >2 ms improvement in bulk minority carrier lifetime at the cell level, resulting in a 4% absolute efficiency boost.
