DISSERTATION IMPACT OF BACK–CONTACT MATERIALS ON PERFORMANCE AND STABILITY OF CdS/CdTe SOLAR CELLS
OF DISSERTATION Impact of Back-contact Materials on Performance and Stability of CdS/CdTe Solar Cells Thin-film CdTe based solar cells are one of the leading contenders for providing lowcost and pollution-free energy. The formation of a stable, low resistance, non-rectifying contact to p-CdTe thin-film is one of the major and critical challenges associated with this technology in the fabricatio...
متن کاملNanowire CdS-CdTe Solar Cells with Molybdenum Oxide as Contact
Using a 10 nm thick molybdenum oxide (MoO3-x) layer as a transparent and low barrier contact to p-CdTe, we demonstrate nanowire CdS-CdTe solar cells with a power conversion efficiency of 11% under front side illumination. Annealing the as-deposited MoO3 film in N2 resulted in a reduction of the cell's series resistance, from 9.97 Ω/cm(2) to 7.69 Ω/cm(2), and increase in efficiency from 9.9% to ...
متن کاملWiring-up carbon single wall nanotubes to polycrystalline inorganic semiconductor thin films: low-barrier, copper-free back contact to CdTe solar cells.
We have discovered that films of carbon single wall nanotubes (SWNTs) make excellent back contacts to CdTe devices without any modification to the CdTe surface. Efficiencies of SWNT-contacted devices are slightly higher than otherwise identical devices formed with standard Au/Cu back contacts. The SWNT layer is thermally stable and easily applied with a spray process, and SWNT-contacted devices...
