As the global effort dedicated to ‘green growth and low-carbon society’ has opened a new era for the renewable energy technology like solar cell, expected solar cell production capacity is expected to exceed 50 GW in 2012. Recent technical break-through in traditional wafer silicon, thin-film solar cells, and new concept of solar cells contributed to lower prices and higher efficiencies for PV energy.

There has been great amount of investment in solar cells and subsequent technical break though. One of the key technologies is based on incident light trapping for better output power gain in various solar cells such as c-Si, mc-Si, a-Si, III-V, II-VI, CdTe, and CIGS. The sharing of new ideas and information in an open forum will allow even greater progress to be made in solar cell research and development. Potential topics include, but are not limited to:

• Silicon surface texture methods and technologies
• TCO light-trapping-related approaches for thin film solar cells
• Plasmon-related light path length modulation
• Substrate (glass, metal, and plastic) surface light trapping structure
• High-efficiency approaches and technologies with solar cell light trapping
• Novel solar-cell-related new process, material, and structure of light trapping
• Low-cost-related material, device, and process
• Other novel solar cell materials and devices
