Equipped with MTTP functionality (Maximum Power Tracking Function), supporting the efficiency improvement of next-generation solar cell development! A "solar cell evaluation device" actively adopted in research fields.
The "PV Power Analyzer (VK-PA-25/VK-PA-Pico)" is a solar cell evaluation device that incorporates research and development functions for evaluating the current-voltage characteristics of solar power generation elements. Many next-generation solar power generation elements exhibit hysteresis characteristics, which pose challenges such as "difficulty in accurate evaluation with conventional current-voltage characteristic assessments" and "the need for long measurement times." By utilizing the built-in MPPT function of this device, effective evaluation can be performed in a short time. Additionally, it is equipped with a function to measure (plot) the time variation of current at a specified voltage, in addition to the conventional current-voltage characteristic (I-V characteristic) measurement function (amperometry). 【Features】 ■ Equipped with MPPT function, enabling efficient evaluation of next-generation solar cells with hysteresis characteristics. ■ In current-voltage measurements, it measures (plots) the time variation of current at the specified voltage.

Company information
I established this research institute with the aim of commercializing the chemical film formation technology I developed while working at the university. Along with the fabrication of related devices, I aim to develop a new dye-sensitized solar cell system that utilizes various films produced by this technology, contributing to energy supply and environmental conservation. I intend for all products to achieve the highest standards in the world.
