Cell-level reliability testing procedures for CIGS photovoltaics
Abstract The reliability of photovoltaics is commonly studied at the module level. Many reliability problems originate from module attributes, such as metal interconnections to cells, junction boxes. However, significant work in reliability can also be done prior to module design. Testing for reliability earlier in the research cycle increases …

If so, keep an eye out for IEC 62716 – this is a test to determine a module''s resistance to ammonia.
Solar Cell Efficiency
Solar cells intended for space use are measured under AM0 conditions. Recent top efficiency solar cell results are given in the page Solar Cell Efficiency Results. The efficiency of a solar cell is determined as the fraction of incident power which is converted to electricity and is defined as: (P_{max }=V_{OC} I_{SC} F F)
