摘要
本文使用专有名词 "Region "来表示 p 型硅晶体中 nm 级的富含掺杂剂区域。利用该区域,假定了某些太阳能电池。通过光子能量与该区域势垒之间的共振吸收,该电池可以吸收可见光频率的大部分光子,而不会产生传递损耗或热损耗。这种光吸收机制不同于传统的带隙吸收。尽管有这一优点,但根据细节平衡原理,输出电压预计会下降。为了控制电压下降,本文提出了两种方法。在理想条件下,计算了几种情况下的理论能量转换效率。计算结果的理论值超过 70%。
Energy conversion efficiency and its improving methods for “Region” solar cell
In this paper, a proper noun “Region” is used for nm-scale n-type dopant-rich region in p-type Si crystal. Using this Region, certain solar cells have been assumed. By resonance absorption between photon energy and potential barrier of the Region, the cell can absorb most photons for visible light frequency without passing loss or thermal loss. This light absorption mechanism is different from conventional band gap absorption. Despite this benefit, output voltage is anticipated to decline according to the principle of detail balance. To control the decline, two methods are proposed in this paper. Theoretical energy conversion efficiencies for several cases are calculated with an ideal condition. The calculation result is over 70% as a theoretical value.
期刊介绍:
Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
