This early solar cell had a conversion efficiency of just 6%. Throughout the 1960s and 1970s, research and development in the semiconductor industry led to higher-quality silicon material with fewer impurities, resulting in …
Solar Cell Efficiency Improvement by New Metallization Techniques
The standard module cell interconnection technique requires printed Ag front side busbars and rear side Ag/Al pads. From the standpoint of cell performance these contacts reduce cell efficiency strongly as a result of large cell shading and reduced surface passivations. Cells without busbars and pads would show a cell current and voltage increase and …
Realistic maximum efficiency of solar energy conversion into work vs exergy efficiency | Energy Efficiency …
A new formalism is used to evaluate the amount of available work transported by the solar energy flux. The formalism is based on the concept of statistically deformed blackbody radiation. It covers cases when the concept of exergy is not fully relevant. An indicator called work content factor $$kappa_{U}^+$$ κ U + is used to …

Solar cells: past, present, future
The efficiency of solar cells can be significantly enhanced by stacking cells with different band gaps on top of each other since this makes better use of the energy contained in the solar spectrum. A complication, however, arises from the fact that each subcell has to generate the same electric current in the case of the conventional two …
