摘要

通过金属有机化学气相沉积法设计和生长了不同面积的 808 nm 十结激光功率转换器（LPC）。比较了芯片在三种不同测试条件下的 I-V 特性，以揭示热积累对 LPC 性能的影响。同时，还研究了芯片尺寸的影响。此外，还根据 LPC 的温度与开路电压（Voc）的线性关系估算了 LPC 的温度。最后，还进行了同步无线信息和功率传输（SWIPT）实验，以研究激光对 SWIPT 性能的限制。实验同时实现了 1.59 W 的功率传输和 200 kbit/s 的数据传输速率。

808 nm Laser Power Converters for Simultaneous Wireless Information and Power Transfer

808 nm ten-junction laser power converters (LPCs) with different areas were designed and grown by metal-organic chemical vapor deposition. The I–V characteristics of the chips under three different testing conditions were compared to reveal the effect of heat accumulation on the performance of the LPCs. At the same time, the chip size effect was studied. In addition, the temperature of the LPCs was estimated based on its linear relationship with open-circuit voltage ( V _oc ). Finally, the experiment of simultaneous wireless information and power transfer (SWIPT) was conducted to study the limitations on the performance of SWIPT based on the laser. A power transmission of 1.59 W and a data transmission rate of 200 kbit/s was achieved simultaneously.

期刊介绍： The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
