  • Publication number: 20080000524
    Abstract: A novel photovoltaic solar cell and method of making the same are disclosed. The solar cell includes: at least one absorber layer which could either be a lightly doped layer or an undoped layer, and at least a doped window-layers which comprise at least two sub-window-layers. The first sub-window-layer, which is next to the absorber-layer, is deposited to form desirable junction with the absorber-layer. The second sub-window-layer, which is next to the first sub-window-layer, but not in direct contact with the absorber-layer, is deposited in order to have transmission higher than the first-sub-window-layer.

  • Patent number: 7245952
    Abstract: The present invention relates to a system and method for compensating for the effects of birefringence in a given sample and employs an optical birefringence analyzer to sense the real-time birefringence contributions and then provides a feedback signal to a compound electro-optical system that negates the birefringence contributions found in the given sample. The birefringence contribution vanishes, thus significantly reducing the main error component for polarimetric measurements.

  • Patent number: 7098058
    Abstract: A method of making a photovoltaic device using light energy and a solution to normalize electric potential variations in the device. A semiconductor layer having nonuniformities comprising areas of aberrant electric potential deviating from the electric potential of the top surface of the semiconductor is deposited onto a substrate layer. A solution containing an electrolyte, at least one bonding material, and positive and negative ions is applied over the top surface of the semiconductor. Light energy is applied to generate photovoltage in the semiconductor, causing a redistribution of the ions and the bonding material to the areas of aberrant electric potential. The bonding material selectively bonds to the nonuniformities in a manner such that the electric potential of the nonuniformities is normalized relative to the electric potential of the top surface of the semiconductor layer. A conductive electrode layer is then deposited over the top surface of the semiconductor layer.

  • Publication number: 20060005273
    Abstract: The present invention provides an efficient and novel maize transformation and regeneration system based on a novel split-seed explant. Mature maize seeds are split longitudinally to form a split-seed explant. The split-seed explant can then be used in transformations to introduce a gene of interest into the maize genome to produce novel maize lines having desired characteristics. The split-seed explant can also be used to generate calli and/or multiple shoots, and rooted plantlets.

  • Patent number: 6731388
    Abstract: Changes in optical properties of layered materials are measured by directing an incident wave of finite transverse dimensions toward layered materials under conditions that will produce a propagating surface mode or a waveguide mode in the layered materials. The intensity distribution is measured within the transverse beam profile of the total reflected beam. The profile shows asymmetric structure associated with the excitation of the propagating surface mode or a wave-guide mode. The index of refraction of the layered materials is modified and the reshaped intensity distribution within the transverse beam profile of the total reflected beam is again measured under the same incidence conditions. The measured intensity distributions are compared to detect differences in the indexes of refraction in the layered materials.
