Photovoltaic-Generated Nanoampere Current Source Designed on Silicon LSIs
In this study, we demonstrates a self-powered self-generated nanoampere current source using a semi-open-circuit photovoltaic cell. This cell was designed by connecting a large resistance to a photovoltaic cell that enabled the output of a very small current. By changing load resistances, the output current can be linearly modified. We have conducted the numerical simulations to validate the concept and discussed effects of load resistance, cell area and light source to output current. Our experiment demonstrated that a sufficiently stable current output can be obtained using different light sources, and inversely linear relationship between the output current and the load resistance was obtained. We anticipate that sufficient photocurrent would be required to stabilize the output current.
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.
