ADVANCEMENTS AND CHALLENGES IN ALL- PEROVSKITE TANDEM SOLAR CELLS: A CRITICAL REVIEW
(CRC Press, 2025) Imran Ullah, Ankit Jain, Anita Shukla, Puspraj Singh Chauhan
This comprehensive review article provides an in-depth examination of the recent advancements and limitations of all-perovskite tandem solar cells (AP-TSCs) with diverse configurations. Metal halide perovskites (MHPs) have garnered significant attention as a promising light absorber material in tandem photovoltaic devices, owing to their tunable bandgaps and robust light absorption capabilities across a broad spectral range of approximately 1.2-2.3 eV. Notwithstanding the remarkable progress achieved in this field, the power conversion efficiency (PCE) and stability of reported AP-TSCs remain inadequate for commercial applications, primarily due to the prevalence of defect activities in both the top wide bandgap (WB) and bottom narrow bandgap (NB) metal halide perovskites (MHPs). These defect activities lead to significant energy losses, thereby hindering the attainment of high PCE values. This article presents a critical examination of the distinct instabilities and energy loss channels inherent to WB-MHPs and NB-MHPs, as well as discusses corresponding strategies aimed at mitigating these issues. Furthermore, the impact of the interconnecting layer on the fabrication of high-quality light absorbers via solution-based methods is discussed. A detailed analysis of the unique requirements and methods for device packaging to enhance the stability of AP-TSCs is also provided. Ultimately, this review offers novel perspectives on the primary challenges, favourable circumstances, and heuristic outlooks for future research endeavours in the realm of AP-TSCs. By addressing the existing limitations and challenges, researchers can unlock the full potential of AP-TSCs, paving the way for the development of high-efficiency, stable, and commercially viable tandem solar cells.
REAL-TIME SOLAR PANEL PERFORMANCE MONITORING AND ENERGY FORECASTING
(CRC Press, 2025) Imran Ullah, Ankit Jain, Anita Shukla, Puspraj Singh Chauhan
Solar Energy is established as an alternative source of energy known as renewable energy. In a developing country like India, the perspective of Solar Energy is important, as it supports a limitless source of energy. Monitoring and prediction of photo-voltaic energy generation help to reduce the energy loss and empower to utilize more energy. Solar energy prediction is challenging as it depends on the fluctuating solar radiations and climate conditions. The problem statement is to monitor electrical parameters of solar panels and predict energygeneration for energy management procedure. In this chapter, the Internet of Things (IoT) is used as a powerful tool for developing a smart solar system-based energy meter. This meter iscapable of transferring information efficiently regarding wireless energy consumption, and at the same time, it is capable of detecting the usage of electricity of solar panels using IoT. A sophisticated digital gadget called a smart energy meter was created to take the place of the conventional electricity meter. By enabling us to manage and lower our energy use, installing a smart meter will help us do away with projected costs. It has the ability to acquire data remotely and submit meter readings to energy providers. The aim of the present work is the measurement of electricity produced by solar panel. Proposed system monitors solar panels and predict the future energy generation for energy management in IoT base environments. The circuit in the current work is interfaced with the ESP32 Wi-Fi module to examine all the requirements for an electrical energy meter using the SCT-013 current sensor and ZMPT101B voltage sensor. The system can send the solar panel data to the Blynk server from all over the world. On the Blynk application dashboard, the voltage, current, power, and overall unit utilized are displayed in kWh.
