“…[ 22,23 ] Although huge experimental successes have been obtained, the poor stability and toxicity of OIHPs have impeded their commercial applications. [ 24,25 ] Lead cations leaked from unencapsulated OIHPs are water‐soluble and can cause non‐negligible harm to water, [ 26,27 ] plants, and the food chain, [ 28 ] which could have an adverse effect on human health. [ 29 ] Furthermore, OIHPs are sensitive to moisture, heat, oxygen, and UV light, [ 9,30,31 ] and halide migration results in severe luminescence shift under intense light or an electric field.…”

Organic–inorganic halide perovskites have attracted extensive attention due to their excellent optoelectronic properties. However, the toxicity of heavy atom Pb2+ and instability overshadow further commercial applications, motivating researchers to explore alternative analogues to overcome these disadvantages. Lead‐free halide double perovskites (HDPs), sharing similar crystal structures with organic–inorganic halide perovskites, are promising candidates for optoelectronic applications. However, HDPs possess unique properties that are uncommon in organic–inorganic halide perovskites deriving from feasible component engineering and strong electron–phonon interaction. Bright luminescence in HDPs originates from self‐trapped excitons (STEs) and sensitized dopants can cover the full visible and near‐infrared ray (NIR) gamut by modulating parity‐forbidden transitions and the energy‐transfer process. The superior optoelectronic characteristics of HDPs further extend applications on self‐assembly, white‐light phosphors, NIR bioimaging, and scintillators, in comparison to organic–inorganic halide perovskites. Herein, the structural diversity, tunable luminescence, photophysical mechanism of STEs, charge‐carrier dynamics, size effect, and stability issues of HDPs are discussed. The challenges and outlook for further investigations are also given, which may help in discovering new analogues and boosting the photoluminescence quantum yield and stability of HDPs.

“…Inevitably, the cell performance limitations are now linked with other parameters such as limiting device lifetime, poor moisture stability of the perovskite, and the toxicity of Pb, which could preclude some application areas for the devices [35,36]. While struggling to invest time on the issues mentioned earlier, optics integration commits an excellent value for efficiency enhancement of the PSC.…”

Integrating Concentrated Optics for Ambient Perovskite Solar Cells

et al. 2021

Metal halide perovskite solar cells (PSCs) are considered an effectual way to enhance photovoltaic (PV) properties, leading to low-cost and high efficiency. PSCs have experienced rapid improvement in the last ten years. The device’s energy production increases extensively in the presence of concentrated light. The use of concentrated optics in solar cells has spurred the PV industry towards tremendous research. Incorporating the concentrated optic into the PV system as a concentrated PV (CPV) means it can capture light effectively and operate at increased efficiencies under concentrated irradiance. This work addresses an initial assessment of the power conversion efficiency (PCE) enhancement of the ambient PSCs by externally integrating concentrated optics. Significantly, the concentrated optics exhibit ~90% of the PCE enhancement under the solar irradiance of 400 W/m2, whereas 16% of the PCE increase was observed when the solar irradiance changed to 1000 W/m2. During optics integration, a considerable elevation of short-circuit current predominately facilitated the overall efficiency enhancement of the PSC. A systematic PV parameters effect on the optic integration on PSCs was further scrutinized. Therefore, this work signifies a possible way to alleviate the PCE of carbon-based PSC using concentrated optics. This work focuses on integrating CPVs into PSCs, preventing PSC stability and scalability issues, with light conditioning techniques.

“…In addition, Su et al (2020) have examined the impact of Pb-leakage on the environment. They have observed that the total organic carbon and chemical oxygen demand analysis signify discarded PSCs could increase the oxygen consumption and may release CO 2 into the environment [116].…”

Perovskite Solar Cells for BIPV Application: A Review

et al. 2020

View full text Add to dashboard Cite

The rapid efficiency enhancement of perovskite solar cells (PSCs) make it a promising photovoltaic (PV) research, which has now drawn attention from industries and government organizations to invest for further development of PSC technology. PSC technology continuously develops into new and improved results. However, stability, toxicity, cost, material production and fabrication become the significant factors, which limits the expansion of PSCs. PSCs integration into a building in the form of building-integrated photovoltaic (BIPV) is one of the most holistic approaches to exploit it as a next-generation PV technology. Integration of high efficiency and semi-transparent PSC in BIPV is still not a well-established area. The purpose of this review is to get an overview of the relative scope of PSCs integration in the BIPV sector. This review demonstrates the benevolence of PSCs by stimulating energy conversion and its perspective and gradual evolution in terms of photovoltaic applications to address the challenge of increasing energy demand and their environmental impacts for BIPV adaptation. Understanding the critical impact regarding the materials and devices established portfolio for PSC integration BIPV are also discussed. In addition to highlighting the apparent advantages of using PSCs in terms of their demand, perspective and the limitations, challenges, new strategies of modification and relative scopes are also addressed in this review.
