Abstract: Provided are a heterojunction solar cell film deposition apparatus, method and system, a solar cell, a module, and a power generation system. The heterojunction solar cell film deposition apparatus is configured for amorphous silicon-based film deposition, and comprises a loading cavity, a preheating cavity, intrinsic process cavities, doping process cavities and an unloading cavity that are linearly arranged in sequence, the cavities being isolated from each other by means of an isolating valve. At least two intrinsic process cavities are provided and are configured for deposition by means of an intrinsic layer silicon film process; and at least one doping process cavity is provided and is configured for deposition by means of an N-type silicon film or P-type silicon film process. The preheating cavity comprises a heating preheating chamber and a preheating buffer chamber that is configured for adjusting the gas and pressure atmosphere.

Abstract: A solar cell simulator that is cylindrically symmetrical to test photovoltaic devices that are flexible. A particular embodiment would be made from plexiglass or similar acrylic material. The present invention produces a spectrum that simulates the spectral distribution of solar light that we observe on the Earth's surface. The simulator would be comprised of a tubular pulsed light source, a pulsed power supply, a tubular light spectrum filter, an IV electrical measurement station, a cylinder-shaped module holder to place the flexible large-area module during the measurement. All cylinders share the same central axis. This maintains radial uniformity of all light intensity and can be used for electrical measurements (IV curves under illumination) of flexible large-area PV modules.

Abstract: Apparatuses and methods are provided for the continuous, roll-to-roll formation of photovoltaic (PV) cells. Apparatuses include reel-to-reel transport chambers, one or more deposition chambers, a differential process isolation unit and a chamber for obtaining real time quality data, including IV data, yield data and uniformity data.

Abstract: Apparatuses and methods are provided for the continuous formation of solar cell material including an isolation chamber that reduces cross contamination between adjacent formation zones that are at different pressures.

Abstract: A process for forming a textured back reflector for a photovoltaic device is provided. The process includes providing a moving substrate, positioning the substrate within a deposition chamber, and sputtering a metal or a metal alloy target positioned within the deposition chamber to produce sputtered material. The process further includes introducing a reacting gas mixed with argon into the deposition chamber. The reacting gas and the sputtered metal or metal alloy material form an alloy layer. The alloy layer is formed on the substrate and provides a textured surface on the substrate.

Abstract: This invention relates generally to thin-film photovoltaic devices, and more specifically to an improved back reflector structure of multiple material layers for being used in thin-film photovoltaic devices. More particularly, the invention is to provide an enhanced back reflector having a texture, a high reflectivity, a high yield, and a long lifetime stability which can be applied into thin-film silicon based photovoltaic devices.

Abstract: Hybrid chemical vapor deposition systems for depositing a semiconductor-containing thin film over a substrate comprise a reaction space, a substrate support member configured to permit movement of a substrate in a longitudinal direction and a plasma-generating apparatus disposed in the reaction space and configured to form plasma-excited species of a vapor phase chemical. The systems further comprise a hot wire unit disposed in the reaction space and configured to heat and decompose a vapor phase chemical. The hot wire unit can be a filament. The systems can further comprise an additional reaction space proximate the reaction space. The additional reaction space can comprise a plasma-generating apparatus configured to form plasma-excited species of a vapor phase chemical and a hot wire unit configured to heat and decompose a vapor phase chemical.

Abstract: Use of a composition that modulates a STAT in the manufacture of a medicament for treating or preventing a fibroproliferative disease. The fibroproliferative disease may comprise keloid scarring. The composition may modulate one or more of; activity; phosphorylation; level of expression; or sub-cellular localisation of the STAT. The STAT may be STAT 3.
