AbstractThe <p> μc-SiC:H / <i> a-Si:H junction can be considered to be a sub-system of a n/i/p solar cell. Optimised performance of this junction can be assumed to be a key feature for obtaining high efficiency solar cells.In this paper the authors present results on the conductivity of boron doped microcrystalline hydrogenated silicon (<p> μc-Si:H) thin films deposited on amorphous substrates (e.g. glass or glass/<i> a-Si:H). It is shown that, without any treatment of the substrate or of the underlying surface, the <p> layers showed a strongly reduced conductivity. This indicates either a bad nucleation or a poor microcrystalline behaviour. By using an appropriate surface treatment of the substrate, a gain in photoconductivity of about three orders of magnitude could be obtained (σ > 3 S/cm at a layer thickness of 400Å). We conclude from this, that for thin <p> type μc-Si:H layers the nucleation conditions are essential for obtaining best electric properties of the film w.r.t. solar cell performance.Based on these results, interface treatment was successfully implemented in n/i/p solar cells deposited on TCO coated glass and stainless steel. The results of these experiments are also presented.

Current Research Interest

Considering the current research interest in Organic / Inorganic (ZnO) hybrid solar cells structures in developing advanced photovoltaic devices, three different types of solar cell structures are proposed. In the proposed structures, hybrid solar cell composed of ZnO nanoparticles are used as an electron-acceptor material and PEDOT:PSS is intruded in between the nanoparticles, which reported to possesses power-conversion efficiency in excess of 8%. The use of p-ZnO layer results to improve the device performance on the rigid substrate. The power-conversion efficiency of the developed solar cell was found to be as high as 10% when measured under AM 1.5G illumination. Further, simulations have been carried out whose results are in line with experimental results.

AbstractWe have shown that high efficiency solar cells can be obtained by incorporating materials of different band gaps in a multijunction configuration. This configuration gives rise to high efficiency due to spectrum splitting as well as superior stability due to thin top cells.We have fabricated multijunction solar cells and acheived a 13% conversion efficiency using 1.7eV a-Si:F:H and 1.5 eV a-Si:Ge:F:H materials in a three-cell triple configuration. This device was deposited onto a stainless steel substrate coated with a back reflector; it also incorporates a microcrystalline p+ layer.The physical properties of each of the solar cell layers and their role in the device physics of a high efficiency solar cell will be described.
