Abstract: Light to current converter devices, such as solar cells, are disclosed. The devices may include via holes extending through the cell substrate and may include through-hole electrodes within the via holes. The through-hole electrodes may be made from one or more materials and may be hollow, partially hollow, or fully filled. Front and rear electrodes may also be formed on the device and can be made of the same or different materials as the through-hole electrode. The devices may include emitters located only on the top surface of the cell, located on the top surface and symmetrically or asymmetrically along a portion of the inner surface of the via holes, or located on the top surface and full inner surface of the via holes. Processes for making light to current converter devices are also disclosed.

Abstract: Back contact solar cell modules and methods of manufacturing the same. The solar cell module comprises a back surface with a plurality of first electrodes and a plurality of second electrodes formed thereon, the plurality of first electrodes and the plurality of second electrodes being of opposite polarities, the back surface being configured to form an electric field thereon of the opposite polarity as the plurality of first electrodes; a first connecting strip electrically connecting the plurality of first electrodes; and an insulative member between the back surface and the first connecting strip.
