Solar energy and other clean energy techniques are emerging and growing rapidly in the globe nowadays. Solar energy and clean energy with less carbon emission are renewable and clean for our living environment. Solar energy can be converted to electricity in photovoltaic (PV) devices, solar cells, or solar thermal/electric power plants. Besides, solar energy and other clean energy techniques can have widespread applications in many energy saving issues.

We invite authors to submit original research articles and review articles that analyze trends, developments, applications, and predictions in this sector. We are particularly interested in articles describing technology and market trends and developments from industry perspective. Potential topics include, but are not limited to:

• Technology trends, developments, applications, and predictions for solar energy
• Market trends, developments, applications, and predictions for solar energy
• Technology trends, developments, applications, and predictions for clean energy
• Market trends, developments, applications, and predictions for clean energy
• Trends and developments in solar photovoltaic (PV) system
• Trends and developments in solar cell
• Trends and developments in solar thermal/electric power plants
• Trends and developments in light-emitting diode (LED)
• Trends and developments in organic light-emitting diode (OLED)
• Thermal image applications in energy conservation
• Signal processing applications in energy conservation and saving issues

Before submission authors should carefully read over the journal’s Author Guidelines, which are located at http://www.hindawi.com/journals/ijp/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/submit/journals/ijp/sece14/ according to the following timetable:
