Definitions

  • Solar cell devices are limited by the collection efficiency of the photovoltaic cells Silicon for example has a band gap of 1.12 eV (electron volts). Photons below that energy cannot excite electrons from the valence band to the conduction band, and thus are lost as heat or by reflection. Photons with energy above 1.12 eV can be collected in silicon solar cell devices, but the energy greater than the bandgap is given up as heat. This process reduces the collection efficiency for higher energy photons.
  • 1.12 eV electron volts
  • Solar cell devices configured (o split the light into different spectral bands allows each band to collect photons with the photovoltaic cells optimized for energy collection in each band.
  • Optical devices configured for splitting implement refractive and/or reflective elements for concentrating light, and splitting elements such as dichroics to separate the bands. Specific placement and orientation of the splitting elements require unique and complicated parts, and precise alignment in order to achieve the desired collection efficiency, making these optical devices difficult and expensive to manufacture.
  • Stacked solar cell devices implement upper and lower photovoltaic cells.
  • the upper photovoltaic cells need to be transmissive to the photons which are collected by the lower cells. Absorptive losses in the top cells reduce the number of photons reaching the lower cells, thereby reducing collection efficiency of the stack
  • transparent conductor layers are generally more resistive which reduces the collection efficiency of the stack. If opaque grid lines are used to collect electrons, the grid line shadows any photovoltaic cells positioned below (he grid line.
