Article Abstract
An insulated building-integrated photovoltaic (PV) roof prototype is designed, developed, and experimentally monitored for the composite climatic conditions in the current work. The prototype is monitored based on hourly indoor room temperature, relative humidity, discomfort index, decrement factor time lag, and power generation. To validate the results, a heat conduction equation was developed and simulated considering actual lower income group (LIG) building size and materials. Second-order polynomial equations were derived from simulation results to optimize insulation thickness. Additionally, the economic analysis of the insulated building-integrated Photovoltaic (BIPV) roof was analyzed and compared to the reinforced concrete cement (RCC) roof. The results reveal that insulated BIPV roofs outperform the RCC roof, reducing indoor temperatures by 3.34 ℃ to 1.37 ℃ within an optimum thickness range of 0.0838-0.1056 m. A time lag of 1 h and a significant reduction in decrement factor up to 0.29 are achieved. The average discomfort index of the proposed roof during sunshine hours was found to be between 23 and 26.5. The insulated BIPV roofs with levelized cost of electricity (LCOE) of the 3.38 Rs/kWh gave a payback period of 6.32 years and a higher internal rate of return of 29.4 compared to RCC roof. The current study increases the feasibility of PV modules to be used as building material.

Semitransparent perovskite solar cells (ST-PSCs) are emerging as promising candidates for tandem architectures and building integrated photovoltaics. However, their development is constrained by a large open-circuit voltage () loss suffered from severe interfacial nonradiative recombination. Here, we propose surface molecular engineering employing tyramine hydrochloride (TACl) at the perovskite/C interface to concurrently passivate interfacial defects and optimize the energy-level alignment.

Semitransparent organic photovoltaics (ST-OPVs) have gained significant attention due to their rapid iteration of high-efficiency photoactive materials and potential applications in building-integrated photovoltaics as smart windows. In this work, we establish a parameter (FoM) to evaluate the potential of photoactive materials for ST-OPVs, combining average visual transmittance, bandgap, and current density. PBOF and eC9 exhibit the highest FoM values of 0.

Flexible all-perovskite tandem solar cells (TSCs) feature an outstanding power-to-weight ratio, rendering them perfect for building-integrated photovoltaic, wearable electronics, and aerospace applications, owing to their adaptability to flexible and lightweight substrates. However, the weak mechanical adhesion between the perovskite and adjacent functional layers, combined with tin (Sn) oxidation at the buried interface in tin-lead (Sn-Pb) narrow-bandgap (NBG) perovskites solar cells (PSCs), substantially hampers the durability and performance of device. Herein, a bilateral anchoring strategy is proposed by employing 2-bromoethylamine hydrobromide (2-BH) at the NBG perovskite/ hole transporting layer (PEDOT:PSS) interface.

Luminescent solar concentrators (LSCs) are promising, cost-effective, large-area solar collectors for building-integrated photovoltaics (BIPVs). However, most of the recently reported efficient LSCs contain heavy metal ions, such as Pb or Cd, which limits their potential practical applications. Here we demonstrated eco-friendly ZnCuInSe/ZnSe (ZCISe/ZnSe) core/shell quantum dots (QDs) and integrated them into a poly(methyl methacrylate) (PMMA) polymer matrix to fabricate LSCs (10 × 10 × 0.
