  • Patent number: 8198125
    Abstract: A method of making a monolithic photovoltaic module having a flexible substrate is described. The method includes the following steps. First, a flexible substrate is provided, and a first adhesive layer, a metal layer, and a second adhesive layer are formed thereon. The second adhesive layer, the metal layer and the first adhesive layer are etched with at least one etching paste. In addition, a patterned semiconductor body layer patterned by an etching paste or a laser scribing is formed thereon. Furthermore, transparent top electrodes patterned by an etching paste or a cold laser scribing are formed on the patterned semiconductor body layer.

  • Publication number: 20110265857
    Abstract: A solar module with a bypass diode integrated therein, fabricated on the basis of the standard thin film solar module. By connecting a series of p-n junction to a non-functional p-n junction in anti-parallel, the non-functional p-n junction in the standard thin film solar module is used as the bypass diode. Hence no additional bypass diode is needed in the design.

  • Publication number: 20110156484
    Abstract: A reliable photovoltaic (PV) power system is provided, including a plurality of smart virtual low voltage PV modules arranged in a plurality of columns and a plurality of rows. The smart virtual low voltage PV modules on the same column are connected in series. The smart virtual low voltage PV modules on the same row are connected in parallel. Each of the smart virtual low voltage PV modules comprises: one or more photovoltaic cells, configured to convert solar energy into DC power. The system further includes a DC/DC converting unit, coupled to the PV module, configured to communicate with a control center to acquire from the control center a determined level value, thereby converting the DC power received from the PV module into a demanded output voltage having the determined level value.

  • Publication number: 20080182420
    Abstract: A method for ensuring the structural integrity of III-nitride opto-electronic or opto-mechanical air-gap nano-structured devices, comprising (a) performing ion beam implantation in a region of the III-nitride opto-electronic and opto-mechanical air-gap nano-structured device, wherein the milling significantly locally modifies a material property in the region to provide the structural integrity; and (b) performing a band-gap selective photo-electro-chemical (PEC) etch on the III-nitride opto-electronic and opto-mechanical air-gap nano-structured device. The method can be used to fabricate distributed Bragg reflectors or photonic crystals, for example.
