Perovskite solar cells have evolved through various architectures to optimize efficiency and stability. The primary configurations include:

1. n-i-p (Normal) Structure

  • Structure: Transparent conductive oxide (e.g., FTO) / Electron Transport Layer (e.g., TiO₂) / Perovskite Layer / Hole Transport Layer (e.g., Spiro-OMeTAD) / Metal Electrode (e.g., Au).
  • Characteristics: This conventional structure has been widely studied and has achieved high power conversion efficiencies.

2. p-i-n (Inverted) Structure

  • Structure: Transparent conductive oxide / Hole Transport Layer (e.g., PEDOT:PSS) / Perovskite Layer / Electron Transport Layer (e.g., PCBM) / Metal Electrode.
  • Advantages: Offers simpler fabrication processes and better stability under certain conditions.

3. Mesoporous Structure

  • Structure: Incorporates a mesoporous scaffold (e.g., TiO₂ or Al₂O₃) between the electron transport layer and the perovskite layer.
  • Benefits: Enhances charge separation and transport, leading to improved device performance.

4. Tandem Cells

  • Structure: Combines perovskite cells with other photovoltaic technologies (e.g., silicon) to form multi-junction devices.
  • Outcome: Achieves higher overall efficiencies by utilizing a broader spectrum of sunlight.

  2. Design and Analysis of Lead-Free Perovskite-Based Solar Cell Devices in Standalone and Tandem Configuration
    Author: Khagendra Prasad Phulara, Selinus University of Science and Literature
    Summary: This dissertation explores the design and analysis of lead-free perovskite solar cells, examining both standalone and tandem configurations to address environmental concerns associated with lead-based perovskites

Here’s a structured summary of the main patterns that consistently emerge across dissertations, research papers, and experimental findings:

1. Material Composition Patterns

  • Most perovskite solar cells use the general formula: ABX₃,
    where:
    • A = organic cation (e.g., methylammonium MA⁺, formamidinium FA⁺, or cesium Cs⁺)
    • B = metal cation (commonly Pb²⁺, but alternatives like Sn²⁺ are explored)
    • X = halide anion (I⁻, Br⁻, Cl⁻)

Pattern Observed:

  • Organic-inorganic hybrid materials show superior performance but lower stability.
  • All-inorganic compositions (like CsPbI₃) improve thermal stability but often struggle with phase stability.

2. Device Architecture Patterns

  • Most research focuses on two main architectures:
    • n-i-p (normal) structure, often with TiO₂ as the electron transport layer.
    • p-i-n (inverted) structure, often using PEDOT:PSS or NiOx as the hole transport layer.

Pattern Observed:

  • Inverted architectures tend to offer simpler fabrication and better compatibility with flexible substrates.

3. Efficiency Improvement Patterns

  • Recurrent strategies include:
    • Interface engineering (modifying layers between perovskite and transport materials).
    • Additive engineering (introducing small molecules or ions to improve crystallinity and reduce defects).
    • Tandem configurations (pairing perovskite with silicon or CIGS to capture more of the light spectrum).

Pattern Observed:

  • Most efficiency jumps come from interface and surface passivation improvements rather than the perovskite layer alone.

4. Degradation and Stability Patterns

  • Stability challenges arise mainly from:
    • Moisture sensitivity.
    • UV and thermal instability.
    • Ion migration under electric fields.

Pattern Observed:

  • Encapsulation and compositional engineering (e.g., using mixed cations or halides) consistently improve stability across studies.

5. Scalability and Manufacturing Patterns

  • Research consistently notes:
    • Lab-scale efficiencies (>25%) are not easily translated to large-area modules.
    • Scalability challenges stem from uniform film deposition, defect control, and reproducibility.

Pattern Observed:

  • Scalable techniques like slot-die coating or blade coating show promise, but reproducibility across large areas remains a common bottleneck.

What is quantum teleportation?

Quantum teleportation is a process by which the quantum state of a particle (such as an electron, photon, or qubit) is transmitted from one location to another without physically moving the particle itself.

Formally, it relies on three key components:

  1. Quantum entanglement — two particles share a special, non-classical link where their states are correlated no matter the distance.
  2. Classical communication — information is sent through normal (non-quantum) channels.
  3. Quantum measurement and reconstruction — the sender (often called Alice) performs a measurement on her entangled particle and the unknown state, then sends the result to the receiver (Bob), who uses it to reconstruct the original quantum state on his entangled particle.
