The efficiency of the solar panels causes loss of large solar generators

Solar panels use sunlight to produce chemical reaction power, how much power and conversion efficiency has important causal relationship, people also study in continuously improve the efficiency of solar panels convert, what are the reason that affect the efficiency of solar panels? 1, low energy photon

solar panel use sunlight to produce chemical reaction to generate electricity. Power generation and conversion efficiency has important causation. People have been research improve the conversion efficiency of solar panels. What are the main reasons that influence the efficiency of the solar panels? 1. Low energy photon energy loss. When the solar panels of the photon energy is less than the band gap of the semiconductor, the photon will directly through semiconductor material, will not be absorbed and won't produce electronic empty hole pair, and the spectral energy loss of about 26%. 2. High-energy light energy loss. When the photon energy dry or equal to the band gap of the semiconductor, photons will be absorbed by the semiconductor material, and dry band gap semiconductor photonic energy will be released in the form of heat, the spectral energy loss of about 40%. 3. Absorption and reflection efficiency loss. Not all of the semiconductor material has the same light absorption ability, and has the highlights in the thickness of the thinner amount of semiconductor material absorption of the photon absorption coefficient and has lower light in the thicker the thickness of the amount of semiconductor material absorption of the photon absorption coefficient is the same. Though the incident photon belong to light effectively, it will be reflection caused by the surface reflection losses. Solar panels is the cause of surface reflection ( 1) Direct reflection of the electrode surface. ( 2) Because of semiconductor materials and the refractive index difference between body of air caused by reflection. 4. Open circuit voltage loss. Light produced by the carrier as the electric field in the PN junction between the hollow charge area and mobile, resulting in polarization charge and voltage is generated. In the PN junction, determined by the impurity concentration diffusion potential release of power can not be removed. The loss factor is called voltage loss, which is about 40%.
