Thin film photovoltaic devices are generally provided having three terminals. In one embodiment, the thin film photovoltaic device can include a first submodule defined by a first plurality of photovoltaic cells between a first dead cell and a first terminal cell; a second submodule defined by a second plurality of photovoltaic cells between a second dead cell and a second terminal cell; and a joint bus bar electrically connected to the first dead cell and the second dead cell. The first dead cell is adjacent to the second dead cell, with the first dead cell being separated from the second dead cell via a separation scribe. Methods are also generally provided for forming a thin film photovoltaic device.

Three terminal thin film photovoltaic module and their methods of manufacture

Methods for cleaning a side edge of a thin film photovoltaic substrate utilizing a laser are provided. The method can include transporting the substrate in a machine direction to move the substrate past a first laser source, and focusing a first laser beam generated by the first laser source onto the side edge of the substrate such that the laser beam removes the thin film present on the side edge of the substrate. An apparatus is also generally provided for cleaning a first side edge and a second side edge of a thin film photovoltaic substrate.

Methods for isolating thin film photovoltaic cells on a superstrate are provided. The method includes focusing a laser beam onto a first surface of the superstrate to remove a thin film stack positioned on a second surface of the superstrate, and directing the laser beam across the first surface of the superstrate to form an isolation scribe that is substantially free from the thin film stack. The thin film stack can include a transparent conductive oxide layer on the second surface, an n-type window layer on the transparent conductive oxide layer, and an absorber layer on the n-type window layer. The laser beam can have a laser wavelength of about 370 nm or less, and/or can have a laser wavelength such that the transparent conductive oxide layer absorbs at least about 80% of the laser beam at the laser wavelength.

A bass drum pedal includes a base frame with a pivotal footplate assembly for driving a rotatable shaft supported on the frame. A hammer is connected to the drive shaft, and is moved to impact on a drum head. A cable connects the footplate to a generally spiral shaped torque arm mounted to the drive shaft. The torque arm is adjustable to vary the amount of footplate movement per unit of hammer sweep. A spring and chain are connected between the frame and drive shaft to return the hammer to a resting position after being operated to impact on the drum. A pair of sprockets are eccentrically mounted with the chain wrapped around them such that the amount of footplate movement per unit of total spring tension can be increased or decreased throughout the hammer stroke. The footplate assembly includes a heel plate, arch plate and toe plate each adjustably attached to a pair of rails pivotally connected to the base frame at the heel end. The heel, arch and toe plates are specially contoured to support the foot and prevent 'cupping' and rolling of the foot during high speed playing. An acoustic drum simulator assembly adjustably secured to the drive shaft is connected to one end of a coil spring wrapped around the drive shaft. The other end of the coil spring is attached to a collar which holds the hammer. The spring allows a limited amount of additional rotation of the drive shaft past the point at which the hammer contacts the drum head, to thereby simulate the feel of an acoustic drum when utilizing the pedal on an electronic drum.
