    摘要: Disclosed are configurations of long-range ordered features of solar cell materials, and methods for forming same. Some features include electrical access openings through a backing layer to a photovoltaic material in the solar cell. Some features include textured features disposed adjacent a surface of a solar cell material. Typically the long-range ordered features are formed by ablating the solar cell material with a laser interference pattern from at least two laser beams.

    摘要: A thin film solar cell and a method fabricating thin film solar cells on flexible substrates. The method includes including providing a flexible polymeric substrate, depositing a photovoltaic precursor on a surface of the substrate, such as CdTe, ZrTe, CdZnTe, CdSe or Cu(In,Ga)Se2, and exposing the photovoltaic precursor to at least one 0.5 microsecond to 10 second pulse of predominately infrared light emitted from a light source having a power output of about 20,000 W/cm2 or less to thermally convert the precursor into a crystalline photovoltaic material having a photovoltaic efficiency of greater than one percent, the conversion being carried out without substantial damage to the substrate.

    摘要: A method for bandgap shift and phase transformation for titania structures. The method can include providing a flexible substrate, depositing a titania film onto the substrate, and exposing the titania film to one or more pulses of infrared energy of sufficient energy density and for a sufficient time to crystallize the titania film to predominantly anatase crystalline phase. The flexible substrate can be formed from a polymeric material, and the method can achieve a bandgap shift from greater than 3.0 eV to approximately 2.4 eV. The method can also include forming a crystalline titania layer over a substrate and annealing the crystalline titania layer by applying pulsed thermal energy sufficient to modify the phase constitution of the crystalline titania layer. The source of pulsed thermal energy can include an infrared flashlamp or laser, and the resulting titania structure can be used with photovoltaic and photoelectrolysis systems.
