A recent study published in African Scientific Reports presents a simplified carrier transport layer-free perovskite solar cell based on LaโNiMnOโ and evaluated using SCAPS-1D simulation. By allowing the absorber to perform light absorption and both electron and hole transport, the design reduces structural complexity, fabrication cost, and potential interface losses. After optimizing absorber thickness, defect density, capture cross-section, and resistive effects, the gold-contact device achieved 30.58% efficiency, while a lower-cost carbon-contact version reached a comparable 30.34%. The findings position LaโNiMnOโ as a promising lead-free material for efficient, stable, scalable, and economically viable photovoltaic technologies.
