摘要： A carrier includes a support frame (10) on which a plurality of wafers (12) are mounted with at least one auxiliary frame (20) for holding the wafers on the support frame. A plurality of clips (24) extend from the auxiliary frame and engage the wafers in pressure engagement, and fasteners (32) retain the auxiliary frame in position with the support frame. Two auxiliary frames can be employed for holding the wafers on opposing sides of the support frame. The support frame and auxiliary frame have electrically nonconducting surfaces. The clips extending from the auxiliary frame are electrically conductive and bridge current from the support frame to the wafers during plating operations. The support frame can also be made to include wafer retention clips, so that the auxiliary frame is not used. The carrier support of the invention can support multiple wafers and yield no significant mechanical stress on the wafers during processing.
摘要翻译：载体包括支撑框架（10），多个晶片（12）在其上安装有至少一个用于将晶片保持在支撑框架上的辅助框架（20）。多个夹子（24）从辅助框架延伸并且以压力接合方式接合晶片，并且紧固件（32）将辅助框架保持在支撑框架的适当位置。可以使用两个辅助框架来将晶片保持在支撑框架的相对侧上。支撑框架和辅助框架具有非导电表面。在电镀操作期间，从辅助框架延伸的夹子是导电的，并且桥接电流从支撑框架到晶片。支撑框架也可以制成包括晶片固定夹，从而不使用辅助框架。本发明的载体支撑件可以支撑多个晶片，并且在处理期间不会对晶片产生显着的机械应力。

摘要： A solar cell is fabricated by etching one or more of its layers without substantially etching another layer of the solar cell. In one embodiment, a copper layer in the solar cell is etched (506) without substantially etching a topmost metallic layer comprising tin. For example, an etchant comprising sulfuric acid and hydrogen peroxide may be employed to etch the copper layer selective to the tin layer. A particular example of the aforementioned etchant is a Co-Bra Etch® etchant modified to comprise about 1% by volume of sulfuric acid, about 4% by volume of phosphoric acid, and about 2% by volume of stabilized hydrogen peroxide. In one embodiment, an aluminum layer in the solar cell is etched (514) without substantially etching the tin layer. For example, an etchant comprising potassium hydroxide may be employed to etch the aluminum layer without substantially etching the tin layer.

摘要： In one embodiment, harmful solar cell polarization is prevented or minimized by providing a conductive path that bleeds charge from a front side of a solar cell (200B) to the bulk of a wafer (203). The conductive path may include patterned holes in a dielectric passivation layer (202B), a conductive anti-reflective coating, or layers of conductive material formed on the top or bottom surface of an anti-reflective coating, for example. Harmful solar cell polarization may also be prevented by biasing a region of a solar cell module on the front side of the solar cell.
摘要翻译：在一个实施例中，通过提供从太阳能电池（200B）的前侧将电荷从晶片（203）的主体出来的导电路径来防止或最小化有害的太阳能电池极化。导电路径可以包括例如在抗反射涂层的顶表面或底表面上形成的电介质钝化层（202B）中的图案化孔，导电抗反射涂层或导电材料层。也可以通过偏置太阳能电池正面上的太阳能电池模块的区域来防止有害的太阳能电池极化。

摘要： In one embodiment, a solar cell module comprises a plurality of solar cells (100) interconnected as a solar cell array. An interconnect assembly electrically connects the backsides of two adjacent solar cells (100). The interconnect assembly may have an interconnect (710) that electrically connects a contact point on a backside of a solar cell (100) to a contact point on a backside of another solar cell (100). The interconnect assembly may further include an interconnect shield (220) placed between the solar cells (100) and the interconnect (710).
