Technical FAQs 4

What are new solar cell designs?

Everyone wants high-efficiency solar modules that generate more power in less space, and new solar cell designs are making this possible. Some of the most exciting developments include: Tandem Solar Cells: These combine perovskite with silicon to push efficiency beyond 30%.

How do solar panels work in 2025?

This guide will break down how solar panels work, explore cutting-edge solar cell innovations, and highlight 2025’s top trends shaping the industry. 1. Heterojunction (HJT) Solar Cells Combine crystalline silicon with thin-film layers for higher efficiency. Lab record: 26.8% efficiency; commercial average: 23–25%.

What is solar cell technology?

Since its inception and early days of conventional polycrystalline and monocrystalline solar cell panels, solar cell technology has made commendable progress. Lately, the industry, with advanced designs like Passivated Emitter and Rear Cell (PERC), Heterojunction (HJT), and Tandem solar cells, is reaching new horizons of efficiency.

Which solar panels use IBC cells?

Sunpower, Aiko, SPIC and Recom are currently the leading manufacturers using IBC cells. However, the latest REC, Longi, Huasun, Trina, and Canadian Solar panels also utilise more efficient N-type heterojunction (HJT) and TOPCon cells.
