You can lower the surface temperature to get better power, or create the solar panels from combined materials (silicon, etc.) into layers to absorb all of the wave length available from the sun.

What are the sutable method to increase efficiency of solar cell?
There are anti-reflective coatings being made. I am not sure about aftermarket use. One using titanium to keep the light heading toward the conversion cell and a method of growing diatoms in a metal enviroment. They use the metal to grow. Their skeletons are used as microreflectors on a PV surface. A cell management system will help. It takes cell output and temp readings and makes the cells run at maximum efficiency.
What does reducing friction increase?
Efficiency Efficiency
How strong is solar power?
That depends on total collection area and the collector efficiency. If you could pave many square miles with high efficiency collectors you would have a very "strong" solar power system. If you only have a single 4 inch diameter solar cell it might not be able to power more than one flashlight bulb.
How does eco homes link with energy efficiency?
IT LINKS WITH ENERGY EFFICIENCY BY USING SOLAR SYSTEM
Why is it difficult to increase the efficiency of a machine?
cheese
Will heating a lithium- polymer cell increase its efficiency?
yes
What is ethylene-vinyl acetate used for?
For Solar Encapsulation. It increases the life of the solar cell. reduces the weight of the solar cell and increases the efficiency of the solar cell. It is also used for the midsole part of your shoe, to create padding, and to add a spring in your step!
How do you increase plating efficiency of a mammalian cell culture?
Use of feeder layer.
How solar power being used today?
The US government is funding research for it to see how to increase solar efficiency and reduce costs. Essentially, as another source of power.
What adaptation would increase the efficiency of active transport of carbohydrates from a plant cell?
large surface areas of the cell surface membrane
When were solar cells invented?
The first solar cell, by Charles Fritts, was invented in 1883, but this was the very first one. This incredibly early solar cell had conversion efficiencies of under 1%. In 1941 and 1954, there were 2 more improvements to the solar cell, the latter being capable of 6% conversion efficiency with direct sunlight.
Would solar panels generate more power at a higher altitude?
When you are at a higher altitude there is less air to dissipate the sunlight, and solar panels increase in efficiency at colder temperatures.

Why is it important for a solar cell to reflect as little light as possible?
Less reflection, more absorbtion. More absorbtion, greater efficiency.

How is the efficiency of a solar panels?
Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight. The energy conversion efficiency (η) of a solar cell is the percentage of the solar energy to which the cell is exposed that is converted into electrical energy.[1] This is calculated by dividing a cell's power output (in watts) at its maximum power point (Pm) by the input light (E, in W/m2) and the surface area of the solar cell (Ac in m2).By convention, solar cell efficiencies are measured under standard test conditions (STC) unless stated otherwise. STC specifies a temperature of 25 °C and an irradiance of 1000 W/m2 with an air mass 1.5 (AM1.5) spectrum. These conditions correspond to a clear day with sunlight incident upon a sun-facing 37°-tilted surface with the sun at an angle of 41.81° above the horizon.[2][3] This represents solar noon near the spring and autumn equinoxes in the continental United States with surface of the cell aimed directly at the sun. Under these test conditions a solar cell of 20% efficiency with a 100 cm2(0.01 m2) surface area would produce 2.0 watts of power.The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m² will produce 200 watts of power at STC, but it can produce more when the sun is high in the sky and will produce less in cloudy conditions and when the sun is low in the sky. In central Colorado, which receives annual insolation of 2200 kWh/m²,[4] such a panel can be expected to produce 440 kWh of energy per year. However, in Michigan, which receives only 1400 kWh/m²/yr,[4] annual energy yield will drop to 280 kWh for the same panel. At more northerly European latitudes, yields are significantly lower: 175kWh annual energy yield in southern England.[5]Several factors affect a cell's conversion efficiency value, including its reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency, and conduction efficiency values.[1]Because these parameters can be difficult to measure directly, other parameters are measured instead, including quantum efficiency, VOC ratio, and fill factor. Reflectance losses are accounted for by the quantum efficiency value, as they affect "external quantum efficiency." Recombination losses are accounted for by the quantum efficiency, VOC ratio, and fill factor values. Resistive losses are predominantly accounted for by the fill factor value, but also contribute to the quantum efficiency and VOC ratio values.In 2013, the highest efficiencies have been achieved by using multiple junction cells at high solar concentrations (43.5% using 418x concentration).
