Research Progress on Different Types of Solar Cells

Abstract

To address global challenges like fossil fuel shortages and climate change, developing clean and renewable solar energy is crucial for the world’s energy transition. Solar cells, which convert sunlight into electricity, are at the forefront of energy technology development. This study uses literature review and comparative analysis to assess the technical features and status of major solar cell types, including crystalline silicon and perovskite cells. Findings show that while crystalline silicon cells are mature and durable, they remain high cost. Perovskite cells, however, have achieved rapid efficiency gains (over 25% in labs), are low-cost, and can be made flexible. Recent progress in improving their stability has further enhanced their application prospects. By comparing efficiency, cost, and stability of different cells, this study helps clarify the current state of solar cell technology and offers guidance for future research and development. With continued efficiency gains and falling costs, solar cells are poised to play a key role in supporting sustainable development goals.
