採用複合拋物面聚光器 (CPC) 和相變材料 (PCM) 的光伏/熱混合系統已成為高效收集太陽能的前景。將PCM結合到CPC的接收器，可以在高輻射期間將多餘的太陽能作為潛熱存儲在PCM中，並在低輻射期間或夜間根據需要釋放。使用PCM可以在相對較高的溫度下儲存熱能，這有利於特定應用。結合 CPC 和 PCM 是一種有效收集和儲存太陽能的方法。本研究根據能量平衡方程的概念，開發了兩種理論模型，包括光伏和 CPC-PVT/PCM 集水器。使用環境參數，包括太陽輻射、風速和環境溫度，作為建模的輸入，從而產生電能和熱能性能。在這項計畫中，我們研究了光伏集熱器系統將太陽輻射轉化為熱能並將該能量存儲在 PCM 中的能力。 集熱器上安裝了CPC以獲得更高的太陽輻射，並進行實驗以比較集熱器在 9 月和 10 月，陰天與晴天的情況。由於同一單元中PCM存儲結構的簡單性，具有 CPC 的光伏/熱能收集器作為太陽能集熱器，以及連接到 PV 模組的吸收板，其固定用於水流的銅管並從相變材料中帶走熱量，使用 MATLAB 和工程方程求解器 (EES) 計算平面 PV 和集熱器系統的數值模型。此處CPC系統的聚光比是 2.3X。 由於光伏模組結合了風冷系統和PCM，表面溫度小於60℃。空氣和水的輸出溫度分別升高到攝氏 48 和 58度。系統的綜合效率預計高達 83%。動態建模模擬結果誤差小於2.3%，可以正確預測CPC-PV/T系統的理論性能。實驗結果顯示，集熱器的總效率在晴天為 65% 至 83%，陰天為 49% 至 75%。當相同的系統在沒有PCM的情況下運行時，溫度顯著升高。研究顯示，所提出的帶有 PCM 的 CPC 光伏系統是一個穩定的系統，旨在利用全光譜太陽光並提高整體性能。

A photovoltaic/thermal hybrid system adopting the compound parabolic concentrator (CPC) and phase change materials (PCM) has become a promising technology for efficiently harvesting solar energy. By incorporating PCM into the receiver of a CPC, the system can store excess solar energy as latent heat in the PCM during times of high solar radiation and release it as needed during periods of low radiation or at night. Using PCM allows storing heat energy at relatively high temperatures, benefiting specific applications. Integrating CPC and PCM is a promising approach for efficiently collecting and storing solar energy. This study develops two theoretical models, including photovoltaic and CPC-PVT/PCM water collector, according to the concept of the energy balance equation. We use environmental parameters, including solar radiation, wind speed, and ambient temperature, as inputs for our modeling, resulting in electrical and thermal energy performances. In this work, we investigate the photovoltaic thermal collector system's ability to convert solar radiation into thermal energy and store that energy in PCM. A CPC has been put on the collector to obtain higher solar radiation. The experiments were conducted to examine how well the collector performed on sunny days compared to cloudy days throughout September and October. Due to the simplicity of the construction for PCM storage in the same unit, a photovoltaic/thermal solar collector with a CPC that serves as a solar collector and the absorber plate attached to the PV module, which holds the copper pipe for water flow and drives heat from phase change material, The numerical models of flat PV and the collector systems are solved using MATLAB and the engineering equation solver (EES). Here, the CPC system's concentration ratio is considered 2.3X. Since the PV module is integrated with an air cooling system and PCM, the surface temperature is less than 60 °C. The air and water output temperatures were raised to 48 and 58 degrees Celsius, respectively. The combined efficiency of the system is anticipated to be up to 83%. With an estimated error of less than 2.3%, the dynamic modeling simulation result can correctly predict the theoretical performance of the CPC-PV/T system. Based on experimental findings, the collector's overall efficiency ranges from 65% to 83% on sunny days and from 49% to 75% on cloudy days. The temperature increased significantly when the identical system was run without the PCM. This study shows that the proposed CPC photovoltaic with PCM is potentially a stable system targeting the utilization of full-spectrum sunlight and enhancing the overall performance.
