Nanowire 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 کاملKey Aspects of CdTe/CdS Solar Cells
Recent developments in the following areas are briefly reviewed: a) the electrical structure of grain boundaries in CdTe absorbers, b) impurities and non-stoichiometry in CdTe solar cells and c) use of Sb2Te3 in contacts to CdTe. Nominally identical solar cells fabricated using 99.999% pure CdTe feedstock from two different suppliers were compared. Differences in the photovoltaic response and a...
متن کاملCurrent Transients in CdS/CdTe Solar Cells
Current transient responses to voltage and illumination steps are investigated to elucidate the mechanisms involved in carrier transport in CdS/CdTe cells. For most cells, the response to a dark, forward-bias step after a long dark soak at zero bias is a current growth curve For one such cell, the magnitude of the transient is ≈ 22% of the starting value with half of the growth occurring within...
متن کاملDISSERTATION 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 کاملMicrolens Array Light Trapping in Cdte/cds Solar Cells
In light of the continued rise in fossil fuel costs, alternative energy sources, such as solar technology, are increasingly important. Concentrating photovoltaic systems are promising for future efficient and cost effective competition with fossil fuels. We employ a microlens array to a CdTe/CdS semiconducting solar cell to increase efficiency via light trapping. Since the microlens array will ...
