this paper introduces a full comparative evaluation of the advanced PV architectures especially for energy harvest application. The comparative evaluation involves module architecture, sub-module architecture, and cell architecture. The comparison includes the capability of theses PV architectures to mitigate the effect of the mismatch loss that inherently comes from different irradiation on the PV system. Then, the effect of the bypass diodes on the PV performance under these three architectures is also considered.A case study is demonstrated to validate the different features of the mentioned PV architectures using PV module consists of 24 PV cells. Finally, simulation and experimental results for PV cell architectures using buck-boost converter is presented to investigate the features of the PV cell architecture and its challenges in the future.

This study provides review of grid-tied architectures used in photovoltaic power systems, classified by the granularity level at which maximum power point tracking (MPPT) is applied. Grid-tied PV power systems can be divided into two main groups, namely centralized MPPT (CMPPT) and distributed MPPT (DMPPT). The DMPPT systems are further classified according to the levels at which MPPT can be applied, i.e. string, module, submodule, and cell level. Typical topologies for each category are also introduced, explained and analyzed. The classification is intended to help readers understand the latest developments of grid-tied PV power systems and inform research directions.

“…To maximize the performance benefits of DMMPT, a dedicated power converter with MPPT function can be assigned to each cell in a PV solar panel [21][22][23][24]. However, a challenge in this cell level DMPPT architecture is to develop a high efficiency power converter and fast MPPT control circuit with low power consumption and small footprint.…”

An on chip integrated power management circuit with maximum power point tracking (PM-MPPT) control is proposed in this paper in order to achieve high efficiency Photovoltaic (PV) system. The proposed PM-MMPT circuit mitigates partial shading issues which exist in PV systems by utilizing cell-level distributed MPPT architecture, where each cell has its own MPPT circuit, in order for each cell to produce its own maximum power without affecting other cells or being affected by other cells. The proposed PM-MPPT circuit consists of two different parts. The first part is a high-efficiency synchronous power converter stage. The second part is an analog ripple correlation control (RCC) MPPT control circuit which provides faster and efficient MPP tracking, has less circuit complexity and low power consumption. HSPICE simulation model of the proposed PM-MPPT circuit is developed with a solar cell that has 0.5 V open circuit voltage and 6 A short circuit current. Simulation results show that the proposed PM-MPPT circuit rapidly tracks the MPP with a tracking efficiency larger than 99% over a wide range of irradiation levels and 92% system power conversion efficiency at a 2 W power level. The detailed analog design of the power stage and the RCC MPPT circuits are presented and discussed in the paper based on 0.35µm CMOS technology. In addition, the PM-MMPT IC layout is presented and discussed. To validate the proposed technique and design, a comparison between the results of the proposed circuit and other reported techniques from the literature is provided. It is shown that the proposed circuit and system are able to operate with the lowest input voltage and the highest output power compared with other reported techniques. Moreover, the proposed design has the smallest size under 2 W power level.
