The performance of silicon solar cells has been significantly improved using an improved PERL (passivated emitter, rear locally diffused) cell structure. This structure overcomes deficiencies in an earlier PERC (passivated emitter and rear cell) cell structure by locally diffusing boron into contact areas at the rear of the cells. Terrestrial energy conversion …
Approaching high efficiency wide range silicon solar cells
Photovoltaic micro energy harvesting for self-sufficient sensor system applications is a promising new market for silicon photovoltaics. Therefore, silicon solar cells need to work under weak light conditions both outdoors, e.g. in the forest, or indoors. Hence, the spectral distribution of the given conditions differs as well with the application. We present a new …

The Mars surface environment and solar array performance
January, 2010, marked the 6th anniversary for MER. This also marked the completion of more than three Martian years of solar array operation on Mars. During the spring of 2010, the MER rovers broke the RTG powered Viking Lander record for robotic operations on the Mars surface. Not only has a wealth of scientific information been obtained from MER but …
Analysis of the potential for a heat island effect in large solar farms
Large-scale solar power plants are being built at a rapid rate, and are setting up to use hundreds of thousands of acres of land surface. The thermal energy flows to the environment related to the operation of such facilities have not, so far, been addressed comprehensively. We are developing rigorous computational fluid dynamics (CFD) …
Stability problems in point contact solar cells
Single-crystal silicon point-contact solar cells show a degradation in their efficiency after being exposed to concentrated sunlight. Two mechanisms appear to be responsible: an increase in surface recombination velocity caused by ultraviolet light, possibly due to electron injection from the silicon into the oxide, and a gradual lowering of the effective …
More than 16% solar cells with a new ''HIT'' (doped a-Si/nondoped …
A HIT (heterojunction with intrinsic thin-layer) structure solar cell has been developed. In this structure, a nondoped a-Si thin layer was inserted between a p-type a-Si layer and an n-layer c-Si substrate. The open-circuit voltage and fill factor (FF) were significantly improved in these HIT structure solar cells compared with conventional p/n …
