研究目的
Investigating the energy harvesting approach for a concentrated photovoltaic (CPV) system based on cell-block-level integrated CMOS converters to enhance solar energy capture.
研究成果
The results demonstrate the potential of the LAMB CPV architecture for enhanced solar energy capture, with the prototype converter achieving high efficiency in a small form factor. This approach offers a promising alternative to traditional tandem-based systems, with potential for higher efficiency and lower cost.
研究不足
The study focuses on a specific CPV system architecture and may not be directly applicable to other types of photovoltaic systems. The prototype converter's performance is evaluated under controlled conditions, and its real-world applicability may vary.
1：Experimental Design and Method Selection:
The methodology involves the development of a miniaturized MISO dc–dc prototype converter operating at 10 MHz in a 130 nm CMOS process. The converter is designed to fit within the available space in a LAMB PV cell block and achieves high efficiency for 45–160-mW power levels.
2：Sample Selection and Data Sources:
The CPV system is built upon the laterally arrayed multibandgap (LAMB) cell structure, with individual cells within a sub-module block connected for approximate voltage matching.
3：List of Experimental Equipment and Materials:
A 130 nm CMOS process is used for the prototype converter.
4：Experimental Procedures and Operational Workflow:
The converter harvests and combines energy while performing maximum power point tracking (MPPT) locally for each cell type.
5：Data Analysis Methods:
The performance of the converter is evaluated based on its efficiency and form factor.
