摘要

所谓的锂电池或结近局部缺陷(JNLD)层装置建立在插入在p-n结附近的发射极中的不连续局部缺陷层(LDL)上,自1992年5月描述以来,引起了许多希望。接下来的两年是虚幻的,因为有许多负面的结果。从20世纪70年代开始,太阳能学界就知道了硅改性扩大其光吸收的概念,而从60年代开始,就提出了内置电场改善的假设,为什么它不起作用?主要的问题是要知道哪些可能适用的改进实际上是重要的,然后把不同的单独证明的现象放在一起。通过将细胞与工作良好的结构进行比较,更容易理解李的概念的矛盾。尽管这两种方法建立在不同的原理上,特别是在插入层精细结构、内置电场分布和电池发射极中的电子输运方面,但最近发表的一些作者的概念和物理模型允许这种分析。

Why Li's solar cell concept cannot work
The so-called Li cell or junction near local defect (JNLD) layer device founded upon a discontinuous local defected layer (LDL) inserted in the emitter near the p-n junction raised many hopes since its description in May 1992. The next two years were delusive because of many negative results. Why does it not work when the concept of Si modification to enlarge its optical absorption has been known in solar community from the 1970s and the built-in electric field improvement postulated since the 1960s? The main problems are to know which potentially applicable improvements are actually important and then to put the different separately proven phenomena together. It is easier to understand the contradictions of Li's concept by comparing the cell with a well-working structure. Some of the authors' concepts and physical modeling published recently allow this analysis although the two approaches are founded on different principles concerning especially the inserted layer fine structure, the built-in electric field distribution, and the electronic transport in the cell emitter.
