In this video the most efficient solar cells tested in the lab are listed as well as the most efficient panels available in the market.

The list includes all major PV technologies such as crystalline silicon, organic solar cells, Multi-junction solar cells, Cd Te, Ga As and Pervoskite etc.

It should be noted that NREL (National Renewable Energy Laboratory) updates the well known efficiency chart for PV lab efficiencies every 6 months. The values listed here in are referenced from the NREL efficiency chart and from own research. The chart can be referenced from the following link:

Note that efficiency noted in the lab will always be higher than practical efficiency.

  1. Yeah..All those cells when they heat up loosing about 40-60% energy output..So what we really need is water cooled solar panels !!! Utilizing hot water and increased efficiency in one !!!! Try to spray any solar panel with water and measure output, you will be surprised how much power got lost when hot !!! For example 250W polycrystalline cells give at solar noon max 100W in sw Florida without water cooling,when spray with water it gives 230W max…That is the reality and they sell you solar panel per watt.Which will never ever produce it's max 250W.The price should be per watt of that 100W output for 250W panel..Yeah..

  2. We will never see the most effective solar panel since they cost too much. For me if it does not work on a cloudy day it is not worth it. The government is not releasing the technologies we need in this dire times. What happened to the infrared solar they proomissed?

  3. What we really need is:

    Most cost effective solar system for a house providing an average of 1,000 kw-hr a month assuming Latitude 30 , mounted on a 30 deg slope roof with peak running east-west. (no rainy days to make it simple)

    Help us actually find what system to BUY.

    Chart it by areas in the nation (eventually for the whole world)… and let the average % of sunny days for any location determine if its worth putting up the panels.

  4. What does efficiency actually mean. is it the out put of the panel in watts divided the amount of power that the panel absorbs.
    be if Ihave a one square metre panel that will absorb say 1000 was the output was say only 100 w then that is 10% .
    Wa aliekum salaam

  5. Did we Americans assist in making this video! It appears we did as it has shit music and no educational narration and fails to describe the cost along with efficiency! This is a terrible format!

  6. in winter my Sun is the fireplace that burn in cabin.24/24 hours. Wil be nice see some thermoresit cell that make 100 watts electricity to battery from fireplace in cabin. I thing to put were is the glass doors.
