INFLUENCE OF BASE THICKNESS ON FRONT AND BACK SIDE EFFICIENCY OF THIN FILM GaAs SOLAR CELLS
نویسنده
چکیده
Compared to conventional solar cells on a substrate, thin film GaAs cells show a higher efficiency at a lower thickness due to back surface reflection. The optimal cell thickness is 1.7 μm. Thin film cells can also be illuminated from the rear side with an efficiency only 15% (relative) lower than for front side illumination.

The Impact of Graphene on the Fabrication of Thin Film Solar Cells: Current Status and Future Prospects
Commercial solar cells have a power conversion efficiency (PCE) in the range of 10-22% with different light absorbers. Graphene, with demonstrated unique structural, physical, and electrical properties, is expected to bring the positive effects on the development of thin film solar cells. Investigations have been carried out to understand whether graphene can be used as a front and back contact...
متن کاملEnhanced photon management in silicon thin film solar cells with different front and back interface texture
Light trapping and photon management of silicon thin film solar cells can be improved by a separate optimization of the front and back contact textures. A separate optimization of the front and back contact textures is investigated by optical simulations taking realistic device geometries into consideration. The optical simulations are confirmed by experimentally realized 1 μm thick microcrysta...

For wafer based silicon solar cells, the combination of amorphous/crystalline silicon (a-Si:H/c-Si) heterojunction emitters (SHJ) [1] and back-contacted back-junction solar cell concepts (BCBJ) [2] offer a very high efficiency potential of around 24%. Stangl et al. proposed a relatively simple and therefore attractive cell concept comprising a two level metallization isolated by an insulation l...
