摘要： An advanced solar cell (10; 10'; 10'') having an improved efficiency over known conventional solar cells uses an external electric field to enhance the conversion of solar energy (P) into electrical energy (I). The cell has a layered extrinsic semiconductor with a lightly doped base layer (12; 50; 90) having opposing incident and collection surfaces (14-16; 52-54; 92, 98), at least one of which has recessed contact regions (18; 56; 94, 100) interspersed between biasing regions (20; 58; 96, 102). The base layer is sandwiched between two oppositely and heavily doped layers (22, 26; 60, 70; 104, 120), at least one of which is substantially confined within the recessed contact regions. Overlaying the biasing region is an enhancement layer (32; 76; 110, 124), such as a layered MOS structure, which is biased. A transparent layer (36; 62; 114) of a conductive material may overlay one of the heavily doped layers or comprise a portion of the MOS structure. A method is provided of converting solar energy (P) into electrical energy (I).

摘要： An advanced solar cell (200) uses an external electric field to enhance the conversion of lightly doped base layer (202) sandwiched between two oppositely and heavily doped layers (215, 22). The heavily doped layers (215) are localized within recessed contact regions (18) which may have varying geometric configurations. These contact regions (18) are interspersed between biasing regions (208) in one or both of opposing incident and collection surfaces. An enhancement layer (32), such as a layered MOS structure overlays the biasing region, and when biased, forms an enhanced depletion region. A transparent layer of a conductive material (36) may overlay one of the heavily doped layers or comprise a portion of the MOS structure. A method is also provided of converting solar energy into electrical energy.
摘要翻译：先进的太阳能电池（200）使用外部电场来增强夹在两个相对和重掺杂的层（215,22）之间的轻掺杂的基底层（202）的转化。重掺杂层（215）位于可具有变化的几何构型的凹入接触区域（18）内。这些接触区域（18）散布在相对的入射和收集表面中的一个或两个中的偏置区域（208）之间。诸如分层MOS结构的增强层（32）覆盖偏置区域，并且当被偏置时，形成增强的耗尽区域。导电材料（36）的透明层可以覆盖重掺杂层中的一个或者包括MOS结构的一部分。还提供了一种将太阳能转化为电能的方法。
